Alien parasite hitchhikes to Patagonia on invasive bumblebee
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, ...
Phoretic mites associated to Bombus pauloensis and Bombus bellicosus (Hymenoptera: Apidae) from Uruguay
(International Bee Research Association, 2019-04)
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
(Oxford University Press, 2020-11)
Classical olfactory conditioning promotes long term memory and improves odor-cued flight orientation in the South American native bumblebee Bombus pauloensis
Study of the acarofauna of native bumblebee species (Bombus) from Argentina
(EDP Sciences, 2011-05)
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 ...
Odor Learning and Its Experience-Dependent Modulation in the South American Native Bumblebee Bombus atratus (Hymenoptera: Apidae)
(Frontiers Media SA, 2018-04)
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 ...
Temporal drop of genetic diversity in Bombus pauloensis
(EDP Sciences, 2019-08)
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 ...
Spatio-temporal dynamics of landscape use by the bumblebee Bombus pauloensis (Hymenoptera: Apidae) and its relationship with pollen provisioning
(Plos One, 2020-07)
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 ...
Pollination Efficiency of Managed Bee Species (Apis mellifera and Bombus pauloensis) in Highbush Blueberry (Vaccinium corymbosum) Productivity
(De Gruyter, 2020-06)
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 ...
Comparison of different pollen substitutes for the feeding of laboratory reared bumble bee (bombus terrestris) colonies
(Research Inst Pomology Floriculture, 2020-06)
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. ...
