Behavioural effects of pesticides in bees--their potential for use in risk assessmentHelen M Thompson
National Bee Unit, Central Science Laboratory, Sand Hutton, York, YO41 1LZ, UK
Ecotoxicology 12:317-30. 2003..Such an approach will require a larger base set of data to predict the longer-term consequences on colonies of short-term effects on individuals, e.g. through population modelling...
Exposure of small mammals, in particular the wood mouse Apodemus sylvaticus, to pesticide seed treatmentsIan Barber
Bayer CropScience, 2 TW Alexander Drive, Research Triangle Park, North Carolina 27709, USA
Environ Toxicol Chem 22:1134-9. 2003..The relevance of these findings when assessing exposure (and risk) posed by seed treatments to wild mammals is discussed...
Modelling long-term effects of IGRs on honey bee coloniesHelen M Thompson
Central Science Laboratory, Sand Hutton, York, UK
Pest Manag Sci 63:1081-4. 2007..Sublethal effects such as precocious foraging can have worse effects than massive brood mortality, as it severely reduces the ability to rear the next generation of nurse bees...
Effects of European foulbrood treatment regime on oxytetracycline levels in honey extracted from treated honeybee (Apis mellifera) colonies and toxicity to broodHelen M Thompson
National Bee Unit, Central Science Laboratory, Sand Hutton, York, UK
Food Addit Contam 22:573-8. 2005..7 mg/kg eight weeks after application. Further work is required to determine whether the levels can be further reduced by changes in the method of application whilst ensuring efficacy and minimizing the effects on brood...
The effects of four insect growth-regulating (IGR) insecticides on honeybee (Apis mellifera L.) colony development, queen rearing and drone sperm productionHelen M Thompson
Central Science Laboratory, Sand Hutton, York, UK
Ecotoxicology 14:757-69. 2005....
Possible chemical causes of skeletal deformities in grey heron nestlings (Ardea cinerea) in North Nottinghamshire, UKHelen M Thompson
Central Science Laboratory, Sand Hutton, York, North Yorkshire YO41 1LZ, UK
Chemosphere 65:400-9. 2006..Further work is underway to identify where the parent birds of the affected nestlings are feeding and identify the possible source of the pollution...
The relevance of sublethal effects in honey bee testing for pesticide risk assessmentHelen M Thompson
Central Science Laboratory, Sand Hutton, York, UK
Pest Manag Sci 63:1058-61. 2007..However, available higher-tier data (semi-field, field tests) should make any additional sublethal testing unnecessary, and higher-tier data should always override data of lower-tier trials on sublethal effects...
Improved approaches to assessing long-term risks to birds and mammalsAndy D M Hart
Central Science Laboratory, YO41 1LZ, Sand Hutton, York, UK
Ecotoxicology 14:771-3. 2005
Risk assessment for honey bees and pesticides--recent developments and 'new issues'Helen M Thompson
The Food and Environment Research Agency, Sand Hutton, York, UK
Pest Manag Sci 66:1157-62. 2010..The occurrence of guttation and the presence of pesticide residues in the fluid are discussed, together with remaining questions that will need to be addressed in answering whether such a route of exposure may pose a risk to honey bees...
