... habitual movements (‘movement memories’) around objects (e.g. a bent trajectory around an object) to reach its destination. 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...

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...

... immunity has been observed in mammals, e.g. primates ( Huffman et al., 2010 ). However, in invertebrates this has never been studied. The bumblebee Bombus terrestris (Linnaeus 1758) is a model species for investigating foraging mechanisms ( Hodges, 1985 ). Bumblebees use both innate and learning...
