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
Scientists from the University of Würzburg have investigated the impact of a new pesticide on the honeybee. In high doses, it has a negative impact on the insects’ taste and cognition ability. In February 2018, the European Food Safety Authority (EFSA) confirmed that the pesticide group of neonicotinoids is harmful to bees. A novel pesticide … More Pesticides give bees a hard time
Study explores 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 … More Pesticides influence ground-nesting bee development and longevity
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
Patagonia may lose its only native bumblebee species due to invasions by alien bee species sanctioned by government policy. In a paper published today in Journal of Applied Ecology, Marcelo Aizen from the Universidad Nacional del Comahue, Argentina, and colleagues from four countries draw attention to the severe conservation, economic and political consequences of intentional species … More Uncoordinated trade policies aid alien bee invasions
First US wild bee map reveals 139 ‘trouble zone’ counties The first-ever study to map U.S. wild bees suggests they are disappearing in the country’s most important farmlands — from California’s Central Valley to the Midwest’s corn belt and the Mississippi River valley. A new study of wild bees identifies 139 counties in key agricultural … More Bee decline threatens US crop production
The tiny pollinators are useful sentinels of what’s going on in an ecosystem, and might just be environmentalists’ best asset. An apiarist tends to beehives at Hastings Urban Farm in Vancouver’s Downtown Eastside. (Courtesy M. Amini) By Rachel Kaufman It’s a sunny day, and Vancouver’s Downtown Eastside neighborhood is buzzing. Commuters are commuting, delivery trucks are delivering, … More Can Honeybees Monitor Pollution?
