Regular periods of abdominal contractions recorded from larvae of the bumblebee, Bombus terrestris (Hymenoptera: Apidae)

European Journal of Entomology, 2006
Using an opto-cardiograph combined with an infrared gas analyzer regular bouts of abdominal contractions were recorded from last instar larva of Bombus terrestris. The rate of CO2 release was about 0.7 ml g-1 h-1.

Rearing of Native Bumblebee Species Bombus haemorrhoidalis for Greenhouse Pollination in Pakistan

Agriculture
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.

Allele specific expression and methylation in the bumblebee, Bombus terrestris

PeerJ, 2015
ABSTRACT The social hymenoptera are emerging as models for epigenetics. DNA methylation, the addition of a methyl group, is a common epigenetic marker. In mammals and flowering plants methylation affects allele specific expression.

How landscape, pollen intake and pollen quality affect colony growth in Bombus terrestris

, 2016
Context: Abundance and diversity of bumblebees have been declining over the past decades. To successfully conserve bumblebee populations, we need to understand how landscape characteristics affect the quantity and quality of floral resources collected by

Colour pattern and DNA-barcoding reveal a wide distribution of the insular endemic bumble bee Bombus xanthopus in the Tuscan Archipelago

The European Zoological Journal
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.
