Microrheology of haemolymph plasma of the bumblebee Bombus terrestris
ABSTRACT Viscosity, which impacts the rate of haemolymph circulation and heat transfer, is one of the transport properties that affects the performance of an insect. Measuring the viscosity of insect fluids is challenging because of the small amount available per specimen.

Infection and transmission of Nosema bombi in Bombus terrestris colonies and its effect on hibernation, mating and colony founding [PDF]
The impact of the microsporidium Nosema bombi on Bombus terrestris was studied by recording mating, hibernation success, protein titre in haemolymph, weight change during hibernation, and colony founding of queens that were inoculated with N.

Winter Active Bumblebees (Bombus terrestris) Achieve High Foraging Rates in Urban Britain [PDF]
BackgroundForaging bumblebees are normally associated with spring and summer in northern Europe. However, there have been sightings of the bumblebee Bombus terrestris during the warmer winters in recent years in southern England.

The adaptive significance of sensory bias in a foraging context: floral colour preferences in the bumblebee Bombus terrestris [PDF]
Innate sensory biases could play an important role in helping naïve animals to find food. As inexperienced bees are known to have strong innate colour biases we investigated whether bumblebee (Bombus terrestris) colonies with stronger biases for the most

Potential application of the bumblebee foraging recruitment pheromone for commercial greenhouse pollination [PDF]
Commercial bumblebee colonies are important crop pollinators. Here we assess whether application of artificial foraging recruitment pheromone can increase foraging activity in Bombus terrestris colonies on a relevant timescale for commercial pollination.

A failed invasion? Commercially introduced pollinators in Southern France [PDF]
The natural diversity of Bombus terrestris subspecies could be under threat from the commercialisation of bumblebees. Therefore, to determine whether commercially imported bumblebees are able to establish and spread, we carried out

Photoreceptor processing speed and input resistance changes during light adaptation correlate with spectral class in the bumblebee, Bombus impatiens. [PDF]
Colour vision depends on comparison of signals from photoreceptors with different spectral sensitivities. However, response properties of photoreceptor cells may differ in ways other than spectral tuning. In insects, for example, broadband photoreceptors,

Sex ratio variation in the bumblebee Bombus terrestris [PDF]
Patterns of sex allocation in bumblebees have been enigmatic and difficult to interpret in either a Fisherian context or in a kinselection perspective. We gathered data on several hundred laboratory-reared colonies of the bumblebee Bombus terrestris and analyzed sex allocation as a function of diapause duration and a series of variables describing ...
