The bumblebees were capable of compensating for the detrimental effects of flower movement on landing performance for flower...

... and sensorimotor control of foraging bumblebees ( Bombus terrestris ). We trained bumblebees to forage in a wind tunnel, and used high-speed stereoscopic videography to record 19,421 landing maneuvers in six sidewind speeds (0 to 3.4 m s −1 ), which correspond to winds encountered in nature. Bumblebees landed less...

... body size and the scaling of morphological traits in bees. To address this knowledge gap, we exposed both males and workers of Bombus terrestris to elevated temperature during development and assessed the effects on (i) the size of morphological traits and (ii) the allometry between these traits...

We investigated whether bumblebees, Bombus terrestris , learn and use movement memories en route to their home. Using a novel experimental paradigm, we habituated bumblebees...

Therapeutic treatment of larvae with biochanin A did not reduce the infection intensity of N. bombi in adults. In contrast, therapeutic treatment of adults did reduce the infection intensity...

... becomes more challenging. Here, we investigated the effect of light intensity on flight control by filming the trajectories of free-flying bumblebees ( Bombus terrestris , Linnaeus 1758) in an experimental tunnel at different light levels. As light levels fell, flight speed decreased and the flight...

...; that is, when it becomes asymmetric. Are bumblebees also able to detect and respond to these unilateral changes in the proximity of the environment at low viewing angles? If so, how and when do they react to these changes? Here, we aimed to answer these questions by presenting bumblebees ( Bombus terrestris L...

We measured thorax temperature, rates of oxygen consumption and carbon dioxide production, and abdominal pumping rates of bees randomly exposed to oxygen levels of 20, 15, 10 and 5 kPa at 26°C. Under normoxia, bumblebees maintained an elevated mean...

The functional significance of these nectar toxins is not fully understood, but they may have a negative impact on pollinator behaviour and health, and, ultimately, plant pollination. This study investigates whether a generalist bumblebee, Bombus terrestris , can...

...Shai Yerushalmi; Shalev Bodenhaimer; Guy Bloch SUMMARY We investigated labor-related plasticity in the circadian clock of the bumblebee Bombus terrestris . Bumblebee workers vary enormously in body size, and we found that size, division of labor, and diurnal rhythms in activity are correlated in B...
