Pesticides deliver a one-two punch to honey bees.

Adjuvants not as benign as previously thought A new article reveals that adjuvants, chemicals commonly added to pesticides, amplify toxicity affecting mortality rates, flight intensity, colony intensity, and pupae development in honey bees. Adjuvants are chemicals that are commonly added to plant protection products, such as pesticides, to help them spread, adhere to targets, disperse … More Pesticides deliver a one-two punch to honey bees.

Pesticides influence ground-nesting bee development and longevity.

A study explores the little-understood effects of soil exposure on subterranean colonies. Results from a new study suggest that bees might be exposed to pesticides in more ways than we thought, and it could impact their development significantly. The study, published in Nature’s Scientific Reports, looks at the non-target effects of pesticides on ground-nesting bees, a group that actually makes … More Pesticides influence ground-nesting bee development and longevity.

Pesticide exposure causes bumblebee flight to fall short. Bees exposed to a neonicotinoid pesticide fly only a third of the distance that unexposed bees are able to achieve.

Flight behaviour is crucial for determining how bees forage, so reduced flight performance from pesticide exposure could lead to colonies going hungry and pollination services being impacted. Foraging bees are essential pollinators for the crops we eat and the wildflowers in our countryside, gardens and parks. Any factor compromising bee flight performance could therefore impact … More Pesticide exposure causes bumblebee flight to fall short. Bees exposed to a neonicotinoid pesticide fly only a third of the distance that unexposed bees are able to achieve.

Common pesticide damages honey bees’ ability to fly

A honey bee (Apis mellifera) is harnessed for study on a flight mill in biology professor James Nieh’s laboratory, UC San Diego. Credit: Simone Tosi, UC San Diego Biologists at the University of California San Diego have demonstrated for the first time that a widely used pesticide can significantly impair the ability of otherwise healthy … More Common pesticide damages honey bees’ ability to fly
