Homing ability of the bumblebee Bombus terrestris (Hymenoptera: Apidae)
The ability of bumblebees to locate their nest site following artificial displacement was investigated. Bombus terrestris (Hymenoptera: Apidae) workers were marked with numbered tags and displaced up to 15 km from their nest. Bees returned from distances of up to 9.8 km, with the proportion of bees returning declining with distance of the release site from the nest. Bees were slow to return to ...
متن کاملNatural variation in the genetic architecture of a host-parasite interaction in the bumblebee Bombus terrestris.
The genetic architecture of fitness-relevant traits in natural populations is a topic that has remained almost untouched by quantitative genetics. Given the importance of parasitism for the host's fitness, we used QTL mapping to study the genetic architecture of traits relevant for host-parasite interactions in the trypanosome parasite, Crithidia bombi and its host, Bombus terrestris. The three...
متن کاملAllele specific expression and methylation in the bumblebee, Bombus terrestris
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. There is contradictory evidence for the role of methylation on allele specific expression in social insects. The aim of this paper is to investigate allele specific expressio...
متن کاملNest wax triggers worker reproduction in the bumblebee Bombus terrestris.
Social insects are well known for their high level of cooperation. Workers of the primitively eusocial bumblebee Bombus terrestris are able to produce male offspring in the presence of a queen. Nonetheless, they only compete for reproduction, in the so-called competition phase, when the workforce is large enough to support the rearing of reproductives. So far, little is known about the proximat...
متن کاملIsolation and characterization of chitin from bumblebee (Bombus terrestris).
Insect chitin possessing shell-like structure was prepared from the bumblebee corpses by a consequent treatment with 1M HCl and 1M NaOH. The bumblebee chitin was compared with crustacean (shrimp) chitin by using elemental analysis, Fourier-transform infrared (FT-IR) and solid-state (13)C cross-polarization magic angle spinning nuclear magnetic resonance (CP/MAS)-NMR spectroscopy and confocal mi...
