Warm or bright – Temperature and light microhabitat use in insect pollinators
We investigated how bumblebee species foraging on a unique flower resource in a heterogeneous habitat might coexist thanks to differential use of light and temperature microhabitats. Our study suggests that temperature acts as a first filter of the local species pool and that, for a given temperature, the present species partition along a light ...

Niche analyses and the potential distribution of four invasive bumblebees worldwide
The introduction of bees for agricultural production in distinct parts of the world and poor management have led to invasion processes that affect biodiversity, significantly impacting native species. Different Bombus species with invasive potential have

Rearing of Native Bumblebee Species Bombus haemorrhoidalis for Greenhouse Pollination in Pakistan
Greenhouse tomato production is a growing business worldwide, and it is strongly promoted by bumblebee pollination. Although there are over 250 bumblebee species worldwide, very few species have been reared successfully for greenhouse tomato pollination.

Insular ecosystems, due to their isolation from the mainland and limited areas, are often endemism hotspots. However, the same factors that drive high endemicity also make islands vulnerable to anthropogenic pressure and thus to biodiversity loss.

Eumelanin and pheomelanin are predominant pigments in bumblebee (Apidae: Bombus) pubescence [PDF]
Background: Bumblebees (Hymenoptera: Apidae: Bombus) are well known for their important inter- and intra-specific variation in hair (or pubescence) color patterns, but the chemical nature of the pigments associated with these patterns is not fully ...

In colonies of Bombus hypnorum reared in captivity all intermediate body sizes between worker and queen are produced, the body size being determined by the amount of food for the larvae. Queens are produced, if the larvae are fed sufficiently. In captivity queens are produced at every time of the colony development, if one worker has to feed only two ...

The combined effects of a monotonous diet and exposure to thiamethoxam on the performance of bumblebee micro-colonies [PDF]
There is a pressing need to better understand the factors contributing to declines of wild pollinators such as bumblebees. Many different contributors have been postulated including: loss of flower-rich habitats and nesting sites; monotonous diets ...
