The worldwide trade in bumblebees can lead to the spread of diseases, which in turn has been claimed as a factor in bumblebee decline. Populations of the introduced Bombus terrestris, which invaded NW Patagonia, Argentina, ...

Bumblebees (Bombus spp.), considered as important angiosperm pollinators, harborseveral mite species associated with their nests. In the present study, 403 bumblebees -B. pauloensis (n=285) and B. bellicosus (n=118) - were ...

Classical olfactory conditioning promotes long term memory and improves odor-cued flight orientation in the South American native bumblebee Bombus pauloensis

A total of 382 bumblebee specimens were examined: Bombus atratus (n=310), Bombus morio (n=42), Bombus bellicosus (n=16), Bombus opifex (n=8), and Bombus tucumanus (n=6). Prevalence, abundance, and intensity of mite infestation ...

Learning about olfactory stimuli is essential in bumblebees' life since it is involved in orientation, recognition of nest sites, foraging efficiency and food yield for the colony as a whole. To evaluate associative learning ...

Bumblebees are economically important insects which perform essential pollination tasks in natural and managed ecosystems. Recent research studying Neotropical bumblebee species in Brazil showed a clear decrease in genetic ...

Understanding how bees use resources at a landscape scale is essential for developing meaningful management plans that sustain populations and the pollination services they provide. Bumblebees are important pollinators for ...

Understanding how bees use the resources provided by crops of massive flowering is essential to develop meaningful agricultural management of plans to maximize the potential of pollination service. We assessed the effect ...

In bumble bee colonies, pollen is the only protein source for larval feeding and its shortage causes a distress in larval development. Adult bumble bees need pollen for the development of glands and the reproductive system. ...
