Behavioural effects of pesticides in bees--their potential for use in risk assessment.
TL;DR: A wide variety of behavioural effects that have been reported in bees following exposure to pesticides, primarily insecticides are reviewed, which range from effects on odour discrimination in the individual to the loss of foraging bees due to disruption of their homing behaviour.
Journal ArticleDOI
Esterases as Markers of Exposure to Organophosphates and Carbamates
Journal ArticleDOI
Potential impacts of synergism in honeybees (Apis mellifera) of exposure to neonicotinoids and sprayed fungicides in crops
TL;DR: Assessment of the toxicity of individual pesticides to honeybees showed that the scale of increase in toxicity was fungicide dose dependent with greater synergy of oral toxicity of thiamethoxam following contact dosing with propiconazole, underlines the need for the use of realistic exposure levels and routes in studies.
Journal ArticleDOI
Interactions between pesticides; a review of reported effects and their implications for wildlife risk assessment
TL;DR: There is a need to develop and validate a standard in vivo test in order to confirm the interaction in those cases where additive or synergistic toxicity results in a high-risk classification.

TL;DR: It is concluded that an integration of diverse approaches is required to predict ‘unexpected’ risks; specifically, ecologically relevant, often long-term and non-lethal, consequences of pharmaceuticals in the environment for wildlife and ecosystems.
