Inbreeding depression and family variation in a social insect, Bombus terrestris (Hymenoptera: Apidae)

Article Abstract:

The fitness of 33 Bombus terrestris colonies resulting from 188 brother-sister matings is compared to that of 43 outbreed colonies. As a population, B. terrestris is likely to cope with inbreeding episodes, however, among-family variation in the effects of inbreeding intensifies the differential representation of families in the population.

Effects of selective episodes in the field on life history traits in the bumblebee Bombus terrestris

Article Abstract:

Bumblebee colonies demonstrated the ability to compensate for environmental costs by delaying reproduction, suggesting improved resistance to parasitism and challenges to the colony's immune system. Early produced workers' generalized immune response appear to indicate a colony's ability to withstand parasitism.

Use of genetic markers to quantify bumblebee foraging range and nest density

Article Abstract:

Genetic markers were used to quantify bumblebee foraging range and nest density. Bumblebee species differ greatly in fundamental aspects of their ecology.
