SASA conducts a wide range of activities monitoring wildlife and the environment in support of a raft of legislation.
Its work on aphid monitoring and phenology are vital in the management of aphid-borne viral disease in Scottish seed potatoes.
It serves as the GM Inspectorate for Scotland.
It provides analytical and forensic support for the investigation of wildlife crime incidents and it provides advice on wildlife management to the Scottish Government and a wide range of stakeholder bodies.
The role of aphids as vectors of potato viruses is of concern to the Scottish seed potato industry. SASA operates a national network of suction traps collecting information about aphid abundance and movement, and providing advice on the risk of virus transmission and the need for aphid control.
The suction trap data contribute to a UK network of traps operated by Rothamsted Research. Weekly aphid bulletins are published by the Rothamsted Insect Survey. The data also contribute to EXAMINE - an EU funded project within the Concerted Action Programme, comprising scientists involved in the collection of national data on aphid distribution, phenology and abundance throughout Europe.
The Entomology laboratory provides technical support to the Aphid Monitoring Programme, introduced into the Seed Potato Classification Scheme in 1992. This programme ensures that seed stocks on which aphids have been poorly controlled can be identified, and that subsequent classification of these stocks is dependent upon a post-harvest tuber test for the presence of viruses.
A development programme to improve our understanding of potato virus epidemiology is underway and has improved the accuracy with which virus levels in seed crops can be forecast.
See the Scottish Aphid Bulletins page for more information.
The Potato Council (PCL) funds 100 in-crop water traps in the major seed growing areas of Great Britain. The trap contents are analysed weekly at the Food and Environment Research Agency in York, with results posted on the PCL website. Users of the service can also sign up to receive e-mail and SMS alerts when Peach-potato aphids (Myzus persicae) are found in their region or when aphid catches in any trap in their region exceed a weekly threshold. Comparative information with previous seasons is also available. NB The PCL site is only available to PCL levy payers and corporate members.
The 'Scottish Aphid Bulletin' consists of a table of 21 species, mostly species of major economic significance, and a second table listing all the other 'non-bulletin' aphids caught during the week.
SASA currently operates three suction traps located at Elgin, Dundee and at SASA's new headquarters at Gogarbank on the west side of Edinburgh. Data from each of these traps are presented as totals for the duration of each report.
Three additional columns of data are also presented under the title of 'Cumulative Totals'. The first presents the total catch from the three traps for the current year, up to and including the period covered by the report. The second column provides the yearly catch of aphids for the equivalent period during the previous year, i.e. 2011. The final column provides the mean cumulative catch of aphids over the same period during the previous 10 years, i.e. 2002-2011. Presenting the data in this way enables the current year's catch of any species to be viewed in the context of data from both the previous year and an average year. As the last column presents an arithmetic mean, this figure is strongly influenced by those years when the total for that particular species of aphid has been high.
In November 2000, the old Elgin trap stopped operating due to the sale of the site. A new Elgin trap was erected approximately 4 kilometres from the old Elgin site. This trap started collecting aphids on 16 May 2002. The 10-year averages for Elgin now consist entirely of data from the new trap. At the end of 2005, the Edinburgh trap ceased operation at the East Craigs site. It was replaced by the Gogarbank trap located 3 kilometres to the south-west of East Craigs. Therefore, the Edinburgh data since 2006 come from Gogarbank and data for all previous years come from East Craigs.
Due to time restraints, data from the Ayr trap will not be included in the Scottish aphid bulletin during 2012. The trap continues to run and we hope to be able to identify catches from it in the future if circumstances improve.
SASA is extremely grateful to the organisations where the traps are sited and to the staff who collect the samples. If you require any further information, or wish to use the contents of the Scottish Aphid Bulletins in any way, please contact Jon Pickup.
The SPCS Aphid Monitoring Programme is suspended for 2013. SASA recommends that growers take advice from their agronomists over their virus management programmes for this season.
The levels of virus present in the 2012 seed crops, which provides the inoculum for virus infection in 2013, were relatively low. The incidence of crops containing leafroll fell to the lowest level on record in 2012 and the incidence of mosaics was the lowest since 2006. As the aphid vectors that transmit the viruses causing mosaics symptoms were very scarce last year, mosaics are expected to fall again in 2013. Although leafroll is expected to be a little more frequently observed this year, levels should not be much above those observed in 2012. Following a moderately cold winter, aphid vectors of leafroll are not expected to be numerous during the early season so the risk of further transmission is low. It is not possible to make long range forecasts of the abundance of the aphid vectors of mosaics. SASA therefore advises growers to consult the aphid monitoring pages where information on the abundance of aphid vectors based on the catches from a network of suction traps and
Prolonged exposure to low winter temperatures are known to have lethal and sub-lethal effects on populations of aphids that sucoverwinter in the larval stage, such as Scottish populations of M. persicae. Poor over-winter survival delays the build up of populations of this species in the forthcoming growing season. Prior to 2011, SASA used the mean temperatures for January and February to predict when M. persicae will become active in the summer. In recent years, following an extremely cold December 2010, SASA predictions of early season aphid activity have been based on the mean temperatures during the three-month period of December-February.
During winter 2012-13, the mean temperatures were close to the average over the past 45 or so years (although a little cooler than most recent winters): 3.7°C at SASA (Edinburgh; mean = 3.8°C) and 3.4°C at JHI (Dundee; mean = 3.5°C). The winter temperatures for 2012-13 rank the 17th coldest over the past 45 years at Edinburgh and 18th coldest over the past 47 years at Dundee.
|2013 Prediction||75% Confidence Limits||2012 Obs'n||
|Myzus persicae||17 June||26 May - 6 July||25 June|
|Macrosiphum euphorbiae||25 May||4 May - 14 June||22 May|
|Metopolophium dirhodum||N/A||24 May|
|Myzus periscae||17 June||23 May - 13 July||27 June|
|Macrosiphum euphorbiae||4 June||12 May - 27 June||23 May|
The 2012-13 winter temperatures suggest that the first flights of M. persicae should be slightly later than average. In 2012, this species was much later than predicted, probably due to the poor spring and early summer weather. Environmental conditions in the months following those used for the predictions are likely to have some influence on aphid activity during the summer. As Metopolophium dirhodum overwinters as an egg, winter temperatures have minimal effect on when this species starts to fly; environmental factors during the weeks prior to flight commencing have a much greater effect.
The prediction for the total of M. persicae caught by 31 July is 14 at Dundee and 10 at Edinburgh. The 75% confidence intervals for these predictions are 3 at the lower end and 49 at the upper for Dundee and 2 at the lower end and 39 at the upper for Edinburgh. Therefore populations of M. persicae are not expected to build up to significant levels during 2013 and seed crops of potato varieties susceptible to leafroll are unlikely to require protection against this aphid during the early part of the 2013 growing season.
From midsummer onwards, the catches of cereal aphids in the suction traps usually dominate the Scottish aphid bulletin and significantly affect the index that is used to estimate the vector pressure for aphid-transmitted potato viruses. Two species, the Rose-Grain aphid (Metopolophium dirhodum) and the Bird Cherry-Oat aphid (Rhopalosiphum padi), are known to be vectors of non-persistently transmitted potato viruses (e.g. PVY) and because they can occur in high numbers in the suction traps, each individual species can make a relatively high contribution to the overall aphid vector pressure index. SASA is currently conducting field trials that support the role of cereal aphids, particularly the Rose-Grain aphid, in virus transmission.
As would be expected, cereal aphids are also important pests of cereal crops, causing direct damage by feeding on crops and through the transmission of viruses such as barley yellow dwarf virus (BYDV).
The four dominant species of cereal aphids were not particularly abundant in the aphid traps in 2011, the population of the Rose-Grain aphid, the species most strongly associated with the transmission of Potato Virus Y (PVY) in Scotland, was slightly greater than in an average year when compared to the previous 28 years. Therefore, it is anticipated that the incidence of plants showing mosaic symptoms will be similar in 2012 to that observed in the 2011 potato crop. However, it is recommended that crops are thoroughly rogued at the earliest opportunity to remove as much virus inoculum and to protect the 2012 seed potato crop from infection.
Potato varieties that have been revealed by virus testing of leaf samples collected during classification inspections as particularly prone to the acquisition of PVY include King Edward, Harmony, Shepody, Maris Peer, Nicola.
Please note that the graphs below represent actual numbers of aphids caught in Scottish suction traps using a log scale. Viewing population data on a log scale makes it easier to spot subtle changes in numbers when comparing 2012 data to the large number of aphids caught in previous seasons.
The total catch of 159 Rose-Grain aphids (Metopolophium dirhodum) in Scottish traps to 26 August ranks 28th from the last 29 years.
As of 26 August, 403 Grain aphids (Sitobion avenae) have been caught in Scottish suction traps in 2012. This total ranks 28th from the last 29 years.
Bird-Cherry Oat aphid
The total catch of 4179 Bird-Cherry Oat aphids (Rhopalosiphum padi) to 26 August 2012 ranks 16th out of the last 29 seasons.
The total catch of 323 Apple-Grass aphids (Rhopalosiphum insertum) to 26 August ranks 25th out of the last 29 seasons. The Apple-Grass aphid is not considered to be a significant vector of potato viruses.
Recent evidence collected at SASA indicates that cereal aphids may have an important role in transmitting PVY, the prevalent cause of mosaics. Metopolophium dirhodum, the species of cereal aphids most closely linked with PVY transmission in Scotland, was exceptionally abundant during 2009 and 2010, suggesting that the incidence of potato plants showing mosaic symptoms in 2011 could be relatively high.
We monitor and report on activity of the Rose-Grain aphid frequently over the period from June to July to ensure that growers have up to date information of the risk of virus transmission. Data are presented on a logarithmic scale to ensure that small but significant early season changes are noticeable.
The first Rose-Grain aphid was caught in the Edinburgh suction trap on 2 June. By 14 August, a total of 2014 had been caught at Edinburgh, which ranks fourth out of the last 28 years.
1779 Rose-Grain aphids had been caught in the Dundee trap prior to 14 August, ranking 15th out of the previous 28 years.
As of 14 August, 668 Rose-Grain aphids had been caught in the Elgin suction trap. This total ranks 7th out of the last 27 years.
The Peach-Potato aphid Myzus persicae has traditionally been considered as the most important aphid vector of potato viruses. However in Scotland, Peach-Potato aphids generally fly later and in far lower numbers than in warmer countries and their relative scarcity generally makes this species less of a concern to potato growers. In some years, usually following a particularly mild winter, Peach-Potato aphids can present a very high risk of virus transmission, particularly Leaf Roll, within the Scottish seed potato crop.
Prolonged exposure to low winter temperatures are known to have lethal and sub-lethal effects on populations of M. persicae which, in Scotland, overwinter in the larval stage. Poor over-winter survival delays the build up of populations of this species in the forthcoming growing season. Prior to 2011, SASA has used the mean temperatures for January and February to predict when M. persicae will become active in the summer. Since 2011, following an extremely cold December 2010, SASA has predicted activity of this aphid using the mean temperatures during the three-month period of December-February.
During winter 2012-13, the mean temperatures were slightly cooler than the long-term average: 3.7°C at SASA (Edinburgh; mean = 3.8°C) and 3.4°C at JHI (Dundee; mean = 3.5°C). These winter temperatures for 2012-13 rank the 17th coldest over the past 45 years at Edinburgh and 18th coldest over the past 47 years at Dundee.
Based on these winter temperatures, predictions indicate that the first flights of M. persicae should occur in mid-June and the total numbers of M. persicae caught by 31 July should be relatively low (see table below).
|First catch in 2013|
|1st catch prediction 2013||N/A||17 June||17 June|
|Mean date of first Catch||4 July||15 June||10 June|
|Catch to 31 July 2013|
|Predicted catch to 31 July 2013||N/A||14||10|
|Mean catch to 31 July||13||42||36|
The 75% confidence intervals for the predictions for the total number of M. persicae caught by 31 July are are 3 at the lower end and 49 at the upper for Dundee and 2 at the lower end and 39 at the upper for Edinburgh. Therefore populations of M. persicae are unlikely to build up to significant levels during the early summer of 2013 and seed crops of potato varieties susceptible to leafroll should not require early season protection against this aphid.
The Potato aphid Macrosiphum euphorbiae is often the most numerous of the five or six species of aphids that regularly colonize potato crops in Scotland. It is also a potential aphid vector of non-persistent potato viruses (e.g. PVY, PVA).
As with Peach-Potato aphids Myzus persicae, predictions made following the 2012-2013 winter indicate that Potato aphid flights ahould be slightly later than in an average year. Therefore, the number of aphids expected tis likely to be slightly lower than normal and the risk of virus transmission to potato crops is not expected to be high. However, environmental conditions over the early summer will influence population development and monitoring of these webpages on a regular basis is recommended.

Inspection of the 2012 Scottish seed potato crop revealed an overall decrease in the area of crops entered for classification that failed to meet the entered grade due to the presence of plants affected with all symptoms of virus. This total decreased from 2.1% in 2011 to 1.1% in 2012. This overall change was as a result of a marked decrease in downgrades due to mild mosaic from 1.2% in 2011 to 0.6% in 2012; a decrease from 0.7% to 0.4% in crops failing to hold grade due to severe mosaic symptoms; and a decrease in leafroll from 0.3% to 0.1%.
Evidence collected at SASA over recent years using field trials to monitor the timing of virus transmission throughout the growing season and correlating changes in virus incidence recorded at crop inspection with aphid activity indicates that cereal aphids have an important role in transmitting PVY, the prevalent cause of mosaics. The evidence revealed a strong relationship between PVY transmission in Scotland and two aphid species: the Rose-Grain aphid Metopolophium dirhodum and the Grain aphid Sitobion avenae. Given the extremely low levels of both of these species during 2012, the prediction for the area of the seed crop failing to hold grade due to mosaic symptoms caused by PVY is expected to decrease further in 2013.
Following the relatively mild winter of 2011-2012, SASA forecast that the first suction trap catches of the Peach-Potato aphid Myzus persicae would be relatively early in 2012 and there was also potential for populations to reach significant levels during the period of crop growth. Probably as a result of the poor summer weather, these populations did not develop in 2012. Consequently, the incidence of leafroll is expected to show only a slight increase from the current very low level.
Following a slightly cooler than average winter in 2012-2013, SASA is forecasting that the first suction trap catches of the Peach-Potato aphid Myzus persicae will occur relatively late, in mid June 2012. The potential for populations to reach significant levels during the period of crop growth is therefore not high. Consequently, the Aphid Monitoring Programme will not be included within the 2013 SPCS requirements. We do however advise growers to check these webpages to see how aphid populations are developing as the season progresses.
An estimate of the likelihood that aphids will transmit non-persistent potato viruses (e.g. PVY) in the field can be made using the data collected by the aphid suction traps. This estimate, the aphid vector pressure, is calculated by summing the total catch of each aphid species, after multiplication by a factor estimating the efficiency of that species as a vector of PVY. Details of the vector efficiencies used in these calculations are available via the Potato Council Aphid Monitoring webpages. The vector pressure is a very coarse measure of the likelihood of virus transmission. Numerous factors will influence virus transmission, including complex interactions between aphid species and the strain of virus they transmit.
The wettest April - June period on record (and further spells of poor weather during July) prevented the build-up of most species of aphid so far this summer. As a result, most species of aphid have been caught at levels well below average for this time of year.
The cumulative aphid vector pressure at Edinburgh on 26 August now stands at 1088, ranking fourteenth out of the previous twenty-nine years. The Bird Cherry-Oat aphid (Rhopalosiphum padi) is responsible for 84% of this figure, the Willow-Carrot aphid (Cavariella aegopodii) for 8% of this figure and the Leaf-curling Plum aphid (Brachycaudus helichrysi) accounts for another 4%.
The cumulative aphid vector pressure for Dundee as of 26 August stands at 527, ranking twenty-fifth out of the previous twenty-nine years. 75% of this value is due to the Bird-Cherry Oat aphid (R. padi), 5% from the Rose-Grain aphid (Metopolophum dirhodum) and 7% due to the Peach-Potato aphid (Myzus persicae).
The cumulative aphid vector pressure for Elgin was 475 on 26 August 2012, ranking eighteenth out of the previous twenty-nine years. 76% of this value is due to the Bird Cherry-Oat aphid (Rhopalosiphum padi), 11% of this value is due to the Willow-Carrot aphid (Cavariella aegopodii) and 5% due to the Leaf-curling Plum aphid (Brachycaudus helichrysi).
SASA are monitoring aphids collected in yellow water traps at two sites:
These traps are changed weekly on Wednesdays and for 2011 we are making the data available on the website as soon as they become available. The traps used are similar to the in-crop traps used in the Potato Council (PCL) funded programme that are analysed at the Food and Environment Research Agency in York, with results posted on the PCL website. We are grateful to Scottish Agronomy for operating the field site in Fife.
The figure compares the aphid vector pressures calculated from the yellow water traps at the two field sites and the aphid suction trap at Gogarbank. The Edinburgh field and suction trap datasets continue to follow the same pattern. The Fife field traps showed a peak in virus pressure during the week beginning 6 July, which was mainly due to a large amount of Rose-Grain aphids caught in traps at that site.
The composition of aphid species differs between the sites and trapping method. For the week beginning 20 July, the Rose-Grain aphid continues to dominate the vector pressures calculated for each trap: with 66% of the at the Gogarbank field site, 61% at the Fife field site and 46% using the Edinburgh suction trap. The Bird Cherry-Oat aphid has less impact: comparable figures are 8% for the Gogarbank field site, 30% at the Fife field site and 34% using the Edinburgh suction trap. Only one Peach-Potato aphid was caught in our field traps this week, at the Fife site. Potato aphids were present in very low numbers at both field sites.
|Black Bean aphid||1%||0%||0%|
|Leaf-curling Plum aphid||3%||4%||2%|
|Bird Cherry-Oat aphid||8%||30%||34%|
SASA provides laboratory based diagnostic support for Scottish bee inspectors in the identification and control of the statutory bee diseases American Foul Brood, European Foul Brood, Tropilaelaps mites and Small Hive beetle. Suspect samples submitted by Scottish bee inspectors are examined for the presence of these statutory bee diseases, and if found SASA provides support in the implementation of legislation and control of these diseases. View more information about bee health in Scotland and the role of the Scottish bee inspectors.
If you think you need to contact a bee inspector, please email Bees Mailbox with your details.
The Scottish Government published a Honey Bee Health Strategy in July 2010. The aim of this Strategy is to achieve a sustainable and healthy population of honey bees for pollination and honey production in Scotland by working with stakeholders with an interest in honey bees. SASA is closely involved in the development and implementation of this ten year action plan.
As part of this action plan, Scottish beekeepers can now sign up to Beebase. This allows beekeepers to register their details free of charge on a secure database and allows them access to an extensive range of information on bee health, including up to date information on the distribution of bee diseases. Knowing the location of Scottish beekeepers will allow us to manage bee diseases more successfully, and improve the health and long term future of the Scottish honey bee.
SASA also provides a diagnostic service on behalf of the Scottish Government to Scottish beekeepers for the presence of Varroa destructor. Samples of hive debris or hive inserts may be sent for diagnosis to "Bee Diseases" at the address in the contact us box on the right of the screen.
The Scottish Government opposes the cultivation of GM crops which could damage Scotland's rich environment and would threaten our reputation for producing high quality and natural foods. It would diminish Scotland's image as a land of food and drink.
Taking account of this policy, SASA provides advice on plant health issues related to the contained use of GMOs and, through the GM Inspectorate, advice and inspection services on the release of GM crop plants into the environment.
Key services provided by the GM Inspectorate are:
SASA also provides a diagnostic testing service for the GM Inspectorate.
Advances in molecular biology in the mid 1970s enable the genetic material of an organism (either DNA or RNA) to be altered using methods that do not occur in nature and these alterations can be replicated and/or transferred to other cells or organisms. These alterations are known as genetic modification (GM) and plants, animals or microbes resulting from such modifications are known as genetically modified organisms (GMOs). GM covers a variety of gene insertion techniques which have been applied worldwide in human and veterinary medicine, horticulture, agriculture and as whole products, or ingredients, in food and feed production.
GM raises important safety issues for human health and protection of the environment. Scottish and UK GM legislation requires that these are addressed at every stage of a GMOs or its product’s development, starting in the laboratory through to commercial production (see UK GM Regulatory Framework).
GMOs are regulated through EU, UK and Scottish legislation each of which requires risk assessments to be carried out at every phase of their development.
The GMO (CU) Regulations cover all aspects of contained use involving genetically modified micro-organims (GMMs) and the human health aspects of contained use involving genetically modified (GM) animals and plants.. The principal legislation is the Genetically Modified Organisms (Contained Use) Regulations 2000 (GMO(CU) and its amendment the Genetically Modified Organisms (Contained Use) (Amendment) Regulations 2002 and the Genetically Modified Organisms (Contained Use) (Amendment) Regulations 2005.
The Scottish Government and the Health and Safety Executive (HSE) are joint Competent Authorities for Contained Use legislation in Scotland. The Scottish Government has lead responsibility in Scotland for the effects from contained use of GMOs (GMMs, GM plants and GM animals) have on the environment. The HSE has lead responsibility for human health and safety throughout Great Britain. The HSE administers the permissions process and enforces the legislation on behalf of the Scottish Government. Further Guidance can be obtained from the HSE website.
In Scotland the EU Directive 2001/18/EC is implemented via the Environmental Protection Act (1990) and the Genetically Modified Organisms (Deliberate Release) (Scotland) Regulations 2002. These provide a statutory safety procedure, involving risk assessment, and the need for prior approval before any GMO can be released or marketed.
Scottish Ministers consent to the release of GM crops for research and development purposes. NIEWS acts as a clearing house for applications for deliberate release; provides the secretariat for the Advisory Committee on Releases to the Environment (ACRE) (see below); and co-ordinates the international presentation of UK policy.
The EU Directive recognises two classes of release depending upon their purpose: Part B releases for research and development and Part C releases for placing on the market. In the UK, Part B consents are granted, on a case-by-case basis, after a detailed risk assessment has been submitted to the Northern Ireland, England, Wales and Scotland GM Unit (NIEWS) in Defra and considered by, a statutory Advisory Committee, consisting of independent scientific experts who advise on the risks to human health and the environment from the release of GMOs. The committee advises Scottish Ministers on whether an application for a release in Scotland should be allowed. Scottish Ministers also take advice from the Health and Safety Executive, the Food Standards Agency and Scottish Natural Heritage as appropriate. Consents set out the conditions and limitations governing releases. Part C releases are granted at the EU level and are effective throughout the EU.
Compliance with the above legislation regulations is established by official inspection. Non-compliance with consent conditions can lead to enforcement action including, where necessary, forwarding cases to the Procurator Fiscal Service. SASA took responsibility for the inspection and enforcement of the deliberate release and marketing of GMOs (principally crops plants) in Scotland in May 2000. At that time, the Central Science Laboratory (CSL) was contracted by Defra to carry out the equivalent inspection and enforcement service for England and Wales. CSL was merged along with a number of Defra’s delivery divisions and Inspectorates to form the Food and Environment Research Agency (Fera).
In April 2004, EU Regulation EC/1829/2003 on GM food and feed came into force throughout the European Union. The regulation provides a single community procedure for the authorisation of any GMO whose produce, or derived products, that are intended for food or feed, including the cultivation of crop plants that are intended for these uses. The majority of marketing applications are now processed through this regulation. This single unified approval for food and feed uses will not then require approval under Part C of Directive 2001/18/EC. The European Food Safety Authority (EFSA) manages the application and authorisation procedure centrally. For applications including cultivation an environmental risk assessment in keeping with the requirements of 2001/18/EC is required, and EFSA is obliged to consult the 2001/18 competent authorities concerning environmental risk assessments. The Foods Standards Agency leads on these applications in the UK, while the role of ACRE is to advise on the environmental risk assessments provided with applications for cultivation. Allied to this regulation are new traceability and labelling rules, EC/1830/2003, which include a threshold of 0.9%, above which the adventitious presence of material from an EU authorised GMO in a non-GM product triggers traceability and labelling of the product. Enforcement of these regulations (1829/2003 and 1830/2003) in Scotland is the responsibility of Local Authority Environmental Health (food) or Trading Standards (feed) Departments.
EU legislation on seeds (notably Directive 2002/53/EC on the Common Catalogue of varieties of agricultural plant species and 2002/55/EC on the marketing of vegetable seed) requires national authorities that have agreed to the marketing of seed of a certain variety on their territory to notify the acceptance of the variety to the European Commission. Seed legislation also requires that genetically modified varieties must be authorised in accordance with EU Directive 2001/18/EC before they are included in the Common Catalogue and marketed in the EU.
Scottish Government GM inspectors are appointed under Part VI of the Environmental Protection Act 1990. The work is in support of the CAP Reform and Crop Policy Branch of the Rural and Environment Directorate who are Scotland’s Competent Authority for the regulation of the deliberate release of GMO’s under EC Directive 2001/18.
For details of the GM legislation that inspectors work to see UK GM Regulatory Framework.
The Food and Environment Research Agency (Fera), is authorised by Defra to carry out equivalent inspection and enforcement services in England. SASA liaises closely with the Scottish Government GM Inspectorate at Fera, particularly in sharing information about seed material that crosses borders for production or marketing, and incidents that are common to both England and Scotland. Northern Ireland and Wales make their own arrangements.
Genetically modified crops are steadily being grown more widely throughout the world since they were first commercialised in 1996. Where GMO crops are grown in seed producing areas, there is a risk of cross-pollination or GM seed inadvertently becoming mixed amongst conventional (non-GM) seedlots. This is known as adventitious GM presence (AGMP).
To assist Scottish merchants, processors and packers (MPP) minimise the risk of marketing seed that may contain AGMP, the GM Inspectorate runs a voluntary scheme to determine whether seed of high risk species has been imported directly into Scotland. Questionnaires are sent out to all MPPs biannually.
To assist seed producers or importers who wish to market agricultural seed for the purposes of tests and trials see Guidance to market seed for tests and trials.
It is important to note that participation in the monitoring programme should not be seen as an assurance that the GM Inspectorate will not exercise its powers in appropriate cases under Part VI of the Environmental Protection Act 1990.
Questionnaires can be returned by email or post. The address for email returns is: GMInspectorate@sasa.gsi.gov.uk. Postal returns should be sent to Scottish Government GM Inspectorate, SASA, Roddinglaw Road, Edinburgh, EH12 9FJ.
A summary of the biannual surveys and any resulting follow-up action is published in the Scottish Government GM Inspectorate’s Annual Report or Reviews.
In seed producing areas where GM crops co-exist with seed crops of conventionally bred varieties, there is a risk that seed from conventionally bred seed may inadvertently contain GM seed (AGMP) through cross-pollination or physical mixing of seed during processing. The legislative EU framework requires the labelling of conventional seed lots that contain any detectable traces of authorised GM seeds. If unauthorised GM seed is found in conventional crop seed, there is zero tolerance and the affected seedlot cannot be marketed.
Risk analyses undertaken on conventionally breed crops suggest that some species are at a higher risk, relative to other crops, from incorporation of adventitious GM material during seed production. Crops that are important to Scottish Agriculture that fall into this high risk category are:
The risk status of all crop species listed above is regularly reviewed.
Importers, producers, processors and merchants of non-GM (conventionally bred) agricultural and vegetable seed are recommended to take all reasonable steps to ensure, before obtaining or marketing high risk category seed it is free of AGMP (see relevant Guidance pages).
Anyone considering marketing, species of certified, conventionally-bred crop varieties in Scotland that are of a high risk category of containing adventitious GM presence are advised to:
In Scotland, high risk category species are winter and spring oilseed rape & related species fodder maize & sweet corn.
This information will assist your company meet your legal duties to ensure that you have taken steps to minimise the risk of adventitious GM presence in conventional seed. It will also help you in answering customers questions relating to adventitious GM presence.
Should you have any queries over these measures contact the Scottish Government GM Inspectorate.
Seed importers that have made a seed declaration on the Scottish Government GM Inspectorate’s Seed Monitoring form are advised to:
These measures should follow the Fera GM Inspectorate Guidance for importers and producers on the prevention of adventitious GM presence in conventional varieties of the relevant crops.
It is the role of the Scottish Government GM Inspectorate to audit seed importers to ensure appropriate steps (due diligence) have been taken and that appropriate documentation is available. We will contact import companies and will request access to the following information:
Should you have any queries over these measures contact the GM Inspectorate.
It is a requirement under the Seed (Scotland) (Amendments for Tests and Trials etc.) Regulations 2007 (2007 No. 224) and Regulation 9 of the Beet Seed No.2. (Scotland) 2010 (2010 No. 148) that authorisation is given by either by the Scottish Government or another European Authority for seed to be marketed for the purposes of conducting tests or trials, including tests for scientific purposes and selection work.
Breeders or Merchants, Processors or Packers based in Scotland should apply for the authorisation to use seed for these purposes by contacting SASA either in writing to Cereals Branch or by telephone (0131 244 8856).
For those species that have a high risk category of containing adventitious GM presence, the SG GM Inspectorate also recommends that you obtain a letter of assurance from the breeder of the variety giving assurances that the seed is free from adventitious GM presence or obtain details of analytical tests on individual seed batches or seedlots, that follow the Fera GM Inspectorate Guidance for importers and producers on the prevention of adventitious GM presence in conventional varieties of the relevant crops.
Should you have any queries over these measures contact the GM Inspectorate.
The GM Inspectorate investigates incidents that arise by through their routine duties or through enquiries that have been brought to the attention the Scottish Government’s CAP Reform and Crop Policy Branch.
Recent incidents have involved the trialling of conventional varieties which contained adventitious GM seed that were not authorised for cultivation.
Investigations are reported to the Scottish Government and are summarised in the GM Inspectorate’s Annual Reports or Reviews.
The Scottish Government GM Inspectorate has agreed to directly monitor or oversee monitoring of sites where inadvertent sowings of GM crop seed took place on three sites in September 2008. Monitoring will continue until the autumn of 2011.
Although all Scottish consents for GM crop research trials have expired, landowners of former GM research trial sites, particularly those for oilseed rape, still have an obligation to ensure the produce of following conventional crops complies with the traceability and labelling requirements for food and feed products of GMOs (EU Regulation 1830/2003). This is because GM oilseed rape volunteers can persist at levels that may require a following non-GM oilseed rape crop to be labelled as ‘GM’.
SASA’s Diagnostic and Molecular Biology Branch provides analytical testing support for the GM Inspectorate by detecting genetically modified material using multi-element profiling and event-specific tests.
SASA is a full member of the European Network of GMO laboratories (ENGL) and is one of three UK National Reference Laboratories who assist the EU Community Reference Laboratory in testing and validating methods for detecting and identifying GMOs. Competence in GMO testing is also maintained by regular participation in ISTA GMO Proficiency Ring Tests.

Many aphid species are specialist herbivores and major pests of agriculture, forestry and horticulture. They have short generation times and rapid growth rates making them one of the invertebrate groups that are most sensitive to climate change.
SASA monitors aphids caught in four 12.2m suction traps operated continuously at Dundee (since 1967), Edinburgh (1969), Elgin (1970) and Ayr (1974). Daily records of abundance of aphid species are available from the main aphid flight season and weekly records from other times.
Within the EU-funded EXAMINE project a consortium of scientists involved in collecting national data on aphid distribution has developed one of the most comprehensive databases for any terrestrial invertebrate group anywhere in the world. EXAMINE covers a network of standard suction traps established in 22 countries, providing a unique resource for studies on the impacts of global change on phenology and abundance(http://www.rothamsted.ac.uk/examine/).
Negative trends were found when the dates of first capture in the Scottish suction traps were examined for 43 out of 46 aphid species over the period 1971–2004. Twenty of these 43 trends were statistically significant and the mean trend indicates that over this 34-year period the date of first capture in 2004 was earlier by 0.47 days/annum or 16 days in total. The average response to temperature was 12.5 days/°C. The green spruce aphid (Elatobium abietinum) has advanced by 4.3 days/decade and 8.1 days/°C and has been proposed as an indicator species for looking at terrestrial phenology (Sparks et al., 2006).
Suction trap catches can be used to study changes in the biodiversity of a wide range of insect groups. Only aphids are currently identified, but historic catches are retained at SASA.

Wildlife crime manifests itself in many ways from the illegal international trade in wildlife to the deliberate persecution of animals. Investigating wildlife crime often requires an unusual set of forensic tools, and here at SASA we have expertise relating to chemical analysis of suspected animal poisoning, and also wildlife DNA forensics.
The illegal poisoning of animals is a particular crime that has persisted in Scotland for decades. It is no surprise that pesticides have emerged as the poisons of choice. Many pest control products (pesticides or biocides) are designed to kill or control invertebrate (insect) or vertebrate (rodent) pests. However, if these chemicals are used incorrectly they can be extremely toxic to animals and humans.
SASA specialises in the detection, identification and quantitation of a wide range of chemicals involved in illegal poisoning. A variety of specimens such as suspected victims and baits, suspicious substances and poisoning paraphernalia are submitted for chemical residue analysis. Analytical results obtained are used as evidence in criminal proceedings or for enforcement of Scottish Government policies. SASA chemists can also be cited to appear as expert witnesses.
At SASA, we carry out wildlife DNA forensic analysis for the police and other organisations involved in wildlife crime investigation. Investigators can find a wide range of evidence that can be subjected to forensic DNA analysis: from trace samples such as blood, fur or feathers, to powdered medicines or ornamental carvings.
At its broadest level, this evidence can be used to identify the species present. From trace evidence or processed products it is often not possible to identify the species present without using DNA based species identification.
Following species identification, it can be necessary to carry out more detailed DNA profiling to tie a suspect to a specific crime. For example paternity testing of captive birds of prey can determine whether the breeding records are correct, or whether birds may have been illegally collected from the wild. It is also possible to use DNA profiling to match a trace sample, such as blood on a suspect’s clothing, to a specific animal carcass – tying the suspect to a specific crime.
In addition to analysing evidence in ongoing wildlife crime investigations, we also carry out research to improve the variety of DNA tests available for the forensic analysis of non-human samples.
SASA is setting up a DNA database to provide a unique identifier for individual rhinoceros horn in UK museums and also zoo animals. This is in response to an increase in rhino horn theft from museums in recent years and an initiative by UK enforcement to crack down on this illegal activity perpetrated by criminal gangs. Unique DNA profiles will be generated from small samples of horn, which will help trace the origin of any stolen rhino horn intercepted by the police or customs.
Museums interested in getting involved with this project should email firstname.lastname@example.org for more information.

Incidents of suspected poisoning of animals by pesticides in Scotland are investigated. The aim of the scheme is to identify any adverse effects on non-target animals that might arise from the approved use of pesticides. If the data gathered by the scheme, and sister schemes throughout the UK, indicate a particular problem, then the registration status of the pesticide concerned is subject to review by the UK regulatory body. The data are also used in the validation and improvement of risk assessments for existing and new compounds.
In cases where there is evidence to indicate either the misuse or the deliberate abuse of pesticides, the results of investigations may also be used in the enforcement of legislation affording protection to animals.
Annual reports on animal poisoning in Scotland from 1999 to date can be downloaded from the Animal Poisoning Reports page.
There is an on-going requirement to develop and refine high quality analytical methodologies to meet demands associated with the introduction of new pesticides, to deal effectively with any concerns relating to existing pesticides, and to make analytical efficiency gains.
Find out more about the analytical techniques currently available.
Information on how to go about reporting pesticide incidents
Incidents of suspected poisoning of animals in Scotland involving;
should be notified to the WIIS scheme operated at SASA on behalf of the Scottish Government.
Samples may be submitted to the scheme by;
Scottish Government Agriculture and Rural Delivery Division - Area Office
In the case of pets, ask your veterinary practice to refer the carcase, or relevant samples, to the local Veterinary Investigation Centre of the Scottish Agricultural College. (Other animals may also be submitted via this route).
Campaign Against Illegal Poisoning of Wildlife - A government led campaign aimed at protecting some of the rarest birds of prey and wildlife, and safeguarding domestic animals established in 1991. Members of the public can report suspicions of illegal poisoning (abuse of pesticides) on a free phone number (0800 321 600). In Scotland this number is linked to the SASA laboratory during working hours, and out of hours messages can be recorded.
The Chemicals Regulations Directorate provide information on pesticides, animal poisoning, and the Campaign Against Illegal Poisoning of Wildlife (CAIP).
General information on reporting other types of pesticide incidents is available from the Health & Safety Executive (HSE).
Environmental contamination incidents in Scotland should be reported to the Scottish Environment Protection Agency (SEPA) Pollution Hotline 0800 80 70 60.
Covering post mortem examinations and pesticide analysis
Post mortem examination is an essential element of the investigation. Other causes of death that may be unrelated to possible exposure to a pesticide can be identified, eliminating the requirement for analysis. Alternatively evidence consistent with poisoning being the cause of death may be gained, and appropriate tissue samples taken for analysis
Field information is used together with the findings of the post mortem examination to determine the extent of any analytical investigation. Analytical techniques and equipment capable of identifying low levels of pesticides considered to present possible hazards to vertebrates or beneficial insects are employed. Multi-residue methods are used for carbamate, organochlorine, organophosphorus, and pyrethroid compounds, and for anticoagulant rodenticides. These are supplemented by compound specific analytical methods for chloralose, metaldehyde, paraquat, strychnine and other compounds. Residues identified are subject to rigorous confirmation criteria for acceptance. The laboratory operates to an internal quality system accredited to the ISO 17025 standard for testing laboratories by UKAS, with some of the above methods included in the scope of accreditation.
Field investigations are often only triggered following the identification of a specific pesticide as the likely cause of poisoning. However field investigations may be initiated following either notification, or after post-mortem examination, if sufficient evidence of pesticide involvement is available.
Field investigations are carried out by Scottish Government Agriculture and Rural Delivery Division Staff, located in Area Offices throughout Scotland. On occasions, these officials may work in joint operations with Police Wildlife Crime Officers.
Further animal samples or other relevant materials obtained during the field investigation are submitted to SASA for analysis.
Field information and residue data are assessed, and where possible incidents of poisoning attributed to one of the following categories of use:
Product used properly in compliance with the label instructions
Accidental or wilful non-compliance with label instructions
Deliberate attempts to poison non-target animals
Residues of pesticides found but levels are probably not indicative of lethal poisoning
Any incident involving a veterinary medicine formulation
Where the cause of death or illness could not be attributed to one of the above categories
At the conclusion of each investigation, an individual incident report is issued to the person who initiated the incident and to partner organisations which participated in the investigation.
A database of incident information (1980 onwards) is maintained, and can be interrogated to provide information required by the Scottish Government and to service requests from other parties.
Details of incidents where pesticides poisoning has been shown to be the cause are forwarded to the UK regulatory body, Chemicals Regulation Directorate (CRD). The data are included in annual reports on the poisoning of animals by pesticides, published by the Environmental Panel of the Advisory Committee on Pesticides. In addition CRD selectively request information from the WIIS database (1972 onwards) to support the ongoing approvals review process.
Where sufficient evidence of the misuse of a pesticide formulation is accrued, then reports by SASA and by Scottish Government Agriculture and Rural Delivery Division Staff may be made to the Procurator Fiscal Service with a view to prosecution. Depending on the circumstances, the Scottish Government may place a legal order on an individual requiring them to take appropriate remedial action to prevent further danger to animals.
Incidents involving the suspected deliberate abuse of pesticides are actively pursued, usually on a multi-agency basis by Scottish Government Agriculture, Food and Rural Communities Directorate Staff, the Police and other partner organisations, with a view to eventual prosecution.
Information on pesticide legislation can be found on the Health & Safety Executive (HSE) website through the link in the Related Links box on the right of the screen.
Scientific advice and technical expertise are provided to Scottish Government (Agriculture, Food and Rural Communities Directorate; and Environment and Forestry Directorate) where conflict arises between mammalian and avian wildlife, agriculture and the environment.
