2017Bombus terrestris (Linnaeus, 1758) Species almost cosmopolitan, with a distribution that extends from northern Europe to north Africa and from central Asia to the Macaronesia, naturally distributed from 0 to 3000 m (Ornosa & Ortiz-Sánchez 2004). It has become increasingly important commercially for its pollination services to agriculture.

Thermoregulation dynamics in commercially reared colonies of the bumblebee Bombus terrestris
, 2021Thermoregulation, that is, the active control of temperature, is key to ensure proper brood development in both wild and captive bumblebee nests. In this study, thermoregulation dynamics were assessed relative to colony age and ambient temperature using ...

The final moments of landing in bumblebees, Bombus terrestris
Journal of Comparative Physiology A, 2016In comparison to other insects, like honeybees, bumblebees are very effective pollinators. Even though landing is a crucial part of pollination, little is known about how bumblebees orchestrate the final, critical moments of landing. Here, we use high-speed recordings to capture the fine details of the landing behaviour of free-flying bumblebees ...

Learning of geometry and features in bumblebees (Bombus terrestris).
Journal of Comparative Psychology, 2013Bumblebees (Bombus terrestris) were trained to find one of the four exit holes located in the corners of an enclosed environment with a distinctive geometry (a rectangular cage). Panels located at the corners provided nongeometric, featural cues. Between trials bumblebees were passively disoriented to disable dead reckoning.
