A scientific note on the reproduction of two bumblebee queens (Bombus hypnorum) infested by the nematode Sphaerularia bombi

In order to investigate the effect of removing a part of the mandible on queen pheromone synthesis, eight of these queens (four of which the left mandible was manipulated and four

Here we deter- mine the spatial distribution and division of labor of workers (Apis mellifera capensis Esch.) fol- lowing a merger of two colonies.. Two unrelated colonies (each

However, several other similar taxa with female colour patterns with broad light yellow bands (Bombus serris- quama Morawitz from Kazakhstan), darker or reduced yellow bands

Abstract – Discontinuous release of CO 2 (bursts) or discontinuous gas exchange cycles (DGC), metabolic rate (MR) and ventilation movements were simultaneously recorded from the

In the present study, we used microsatellite DNA analysis to estimate queen mating frequency and the genetic relatedness among workers of two colonies of the Himalayan giant

Investigators have shown (Stanghellini et al. 2008 ) that commercial bumble bee (Bombus impatiens Cresson, Hymenoptera: Apidae) colonies can serve as potential alternative hosts for

The present research is the first study on the acarofauna associated with the most abundant species of native bumblebees from Argentina, with the purpose to add information about

Here, we report Bombus insularis (Smith) invading the nest of two bumblebee species in the subgenus Pyrobombus, Bombus huntii Greene, and Bombus bifarius Cresson, and
