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 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...
متن کاملBird Mite Infestation
Mites in the genus Dermanyssus are external parasites of birds, rodents and other mammals. The most common member of this group is the Chicken Mite that infests poultry roosts and wild bird nests. The chicken mite feeds primarily at night when the birds return the nest or roast area. They hide during the day in nearby cracks, crevices and other protected sites. These mites are known to infest h...
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 کاملBumblebees (Bombus terrestris) use social information as an indicator of safety in dangerous environments.
Avoiding predation is one of the most important challenges that an animal faces. Several anti-predation behaviours can be employed, yet simply using the presence of conspecifics can be a good signal of safety in an environment with potential predation hazards. Here, we show, for the first time, that past experience of predation causes bumblebees (Bombus terrestris) to aggregate with conspecific...
