Implication

Laboratory experiments reveal that chronic pesticide exposure alters bumble bee locomotion, indicating ecological risks.

Key Points

  • This research investigates how chronic exposure to pesticides affects the foraging behavior and locomotor activity of bumble bees.
  • Conducted laboratory experiments with bumble bees (Bombus terrestris) exposed to various pesticides and a biopesticide.
  • Tested foraging avoidance for contaminated honey syrup using neonicotinoids, herbicides, and fungicides.
  • Assessed individual and colony-level behavior and effects on locomotion after exposure.
  • Bumble bees showed no avoidance of contaminated food across pesticide categories at both individual and colony levels.
  • Exposure to the biopesticide resulted in reduced food consumption and lower survival rates of individual bees.
  • Pesticide exposure increased resting time, meandering, and decreased speed and movement of bumble bees.
