1. #AnimBehav2021 Pesticides can alter animal #behaviour. While Risk Assessments aim at protecting animals from unacceptable #pesticide risks, behavioural impacts are often marginally considered. Thread: variety of pesticide sublethal effects on our model species, the #honeybee

2. Flight. Pesticides can alter honey bee flight ability (speed, distance) in the short & long term (acute & chronic exposure). We used specifically built flight mills to test this behaviour w/ @jnieh

3. Motor functions, activity level, orientation to light. Pesticides alter bee phototaxis and their locomotion (ability to climb and walk) in the short and long term. We built an arena to test this behaviour

4. #thermoregulation. Honey bees thermoregulate to fly efficiently, to maintain their nest at 35°C (necessary for healthy development), etc. Pesticides can alter such vital ability

Bee health and behaviour research

Simple: videos about research on bee health and their behaviour.

5. Bees (& most animals, including humans) are exposed to multiple pesticides simultaneously. Pesticide combinations can synergistically amplify the behavioural effects caused on bees:

6. Behavioural effects can harm health & survival in bees, but pesticides are often approved without proper sublethal testing. Suggestions:
*more research & discussions to refine behavioural assessments
*implement new knowledge in Risk Assessment & Protection Goals
