Glyphosate impairs collective thermoregulation in bumblebees

Anja Weidenmueller et al.

Summary: This study investigated the impact of glyphosate on bumblebees and found that long-term exposure to glyphosate results in a decreased thermoregulation ability in bumblebee colonies, which is important for pollinators in ecosystems.

Thermoregulation dynamics in commercially reared colonies of the bumblebee Bombus terrestris

Enya Wynants et al.

Summary: This study found that the thermoregulation investment of bumblebees was lowest when the brood surface temperature was between 33 and 34 degrees Celsius and the ambient temperature was between 28 and 32 degrees Celsius. Additionally, younger nests showed higher thermoregulation investment, especially at lower ambient temperatures. Furthermore, queens initiated colonies sooner and colonies developed faster when kept at 29 degrees Celsius compared to 24 degrees Celsius.

Higher developmental temperature increases queen production and decreases worker body size in the bumblebee Bombus terrestris

Marie Guiraud et al.

Summary: This study found that when exposed to temperatures above optimal levels, Bumblebee colonies had increased queen production and reproductive investment, but worker bees were significantly smaller, which could impact resource collection and pollination, ultimately leading to a negative impact on colony fitness.
