Mechanosensory hairs in bumblebees (Bombus terrestris) detect weak electric fields.
Bumblebees (Bombus terrestris) use information from surrounding electric fields to make foraging decisions. Electroreception in air, a nonconductive medium, is a recently discovered sensory capacity of insects, yet the sensory mechanisms remain elusive. Here, we investigate two putative electric field sensors: antennae and mechanosensory hairs. Examining their mechanical and neural response, we...
متن کاملSpatial Vision in Bombus terrestris
Bombus terrestris is one of the most commonly used insect models to investigate visually guided behavior and spatial vision in particular. Two fundamental measures of spatial vision are spatial resolution and contrast sensitivity. In this study, we report the threshold of spatial resolution in B. terrestris and characterize the contrast sensitivity function of the bumblebee visual system for a ...
متن کاملMolecular heterochrony and the evolution of sociality in bumblebees (Bombus terrestris).
Sibling care is a hallmark of social insects, but its evolution remains challenging to explain at the molecular level. The hypothesis that sibling care evolved from ancestral maternal care in primitively eusocial insects has been elaborated to involve heterochronic changes in gene expression. This elaboration leads to the prediction that workers in these species will show patterns of gene expre...
متن کاملThe genetic architecture of immune defense and reproduction in male Bombus terrestris bumblebees.
Understanding the architecture of genetic variation, that is the number, effect, location, and interaction, of genes responsible for phenotypic variability in nature is important for the understanding of microevolutionary processes. In this study, we have used a quantitative trait loci (QTL) approach to uncover the genetic architecture of fitness-relevant traits associated with reproduction and...
متن کاملDaily changes in ultraviolet light levels can synchronize the circadian clock of bumblebees (Bombus terrestris).
Endogenous circadian clocks are synchronized to the 24-h day by external zeitgebers such as daily light and temperature cycles. Bumblebee foragers show diurnal rhythms under daily light:dark cycles and short-period free-running circadian rhythms in constant light conditions in the laboratory. In contrast, during the continuous light conditions of the arctic summer, they show robust 24-h rhythms...
