Survival rate and changes in foraging performances of solitary bees exposed to a novel insecticide
Solitary bees are among the most important pollinators worldwide however population declines especially in croplands has been noticed. The novel pesticide sulfoxaflor is a competitive modulator of nicotinic acetylcholine receptors (nAChR) in insects ...

Desynchronizations in bee–plant interactions cause severe fitness losses in solitary bees [PDF]
Abstract Global warming can disrupt mutualistic interactions between solitary bees and plants when increasing temperature differentially changes the timing of interacting partners. One possible scenario is for insect phenology to advance more rapidly than plant phenology.

Foraging ranges of solitary bees
Summary Habitat requirements of solitary bees include nesting sites, food resources and nesting material. We used translocation experiments to establish foraging distances and measured foraging trip duration to analyse how solitary bees cope with the distance between nesting sites and suitable food plants in different habitat types.

Wild bee toxicity data for pesticide risk assessments [PDF]
Pollination services are vital for agriculture, food security and biodiversity. Although many insect species provide pollination services, honeybees are thought to be the major provider of this service to agriculture. However, the importance of wild bees

Effects of heat shocks, heat waves, and sustained warming on solitary bees
Along with higher average temperatures, global climate change is expected to lead to more frequent and intense extreme heat events, and these different types of warming are likely to differ in their effects on bees. Although solitary bees comprise >75%

For most people the beehive and the intricate social organization of the honeybees that populate it are the hallmark of bee life. In reality more than 85 percent of the some 20,000 bee species are not social but solitary. Each female independently mates, makes her own nest of about 10 brood cells, stocks the cells with food for the young, lays an egg ...
