Breakthrough could aid development of bee-friendly pesticides. Efforts to create pesticides that are not toxic to bees have been boosted by a scientific breakthrough. A joint study by the University of Exeter, Rothamsted Research and Bayer AG has discovered the enzymes in honeybees and bumblebees that determine how sensitive they are to different neonicotinoid pesticides. The … More Breakthrough could aid development of bee-friendly pesticides.
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.
Bees living in suburban habitats are still being exposed to significant levels of pesticides despite the EU ban on the use of neonicotinoid pesticides on flowering crops, new research from University of Sussex scientists shows. While the introduction of new EU restrictions on the use of neonicotinoid chemicals five years ago has reduced exposure of … More Study shows EU pesticide ban failing to protect suburban bees.
Pesticide regulations designed to protect honeybees fail to account for potential health threats posed by agrochemicals to the full diversity of bee species that are even more important pollinators of food crops and other plants, say three new international papers co-authored by University of Guelph biologists. As the global human population grows, and as pollinators … More Stronger pesticide regulations likely needed to protect all bee species, say studies.
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 … More Pesticide exposure causes bumblebee flight to fall short.
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.
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.
