Insects, 2022 Bumblebees are key pollinators in agricultural landscapes. However, little is known about how gut microbial communities respond to anthropogenic changes. We used commercially produced colonies of buff-tailed bumblebees (Bombus terrestris) placed in three

Environmental Toxicology, EarlyView.ABSTRACT Brazilian social stingless bees are important pollinators and producers of honey, wax, royal jelly, propolis, and other products. These species are experiencing a population decline, attributed to different factors, such as the excessive use of pesticides.

Methylation and worker reproduction in the bumble-bee (Bombus terrestris) [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2014 Insects are at the dawn of an epigenetics era. Numerous social insect species have been found to possess a functioning methylation system, previously not thought to exist in insects. Methylation, an epigenetic tag, may be vital for the sociality and division of labour for which social insects are renowned.

Review of the methods to determine the hazard and toxicity of pesticides to bumblebees [PDF]
, 2001 Methods to determine the impact of pesticides on bumblebees are described. They are classified into laboratory tests to determine the acute toxicity and the hazard to bumblebees, (semi) field tests, and brood tests.

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem services provide essential benefits to human survival and well‐being. Animal behaviour is central to the delivery of many ecosystem services, yet we know little about how behaviour drives services' provision.

Size variation and foraging rate in bumblebees ( Bombus terrestris ) [PDF]
Insectes Sociaux, 2002 Summary. Size polymorphism is an important life history trait in bumblebees with strong impact on individual behavior and colony organization. Within a colony larger workers tend to serve as foragers, while smaller workers fulfill inhive tasks. It is often assumed that size-dependent division of labor relates to differences in task performance. In this

Warming and community context drive rapid plant evolution
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Abiotic and biotic factors are important drivers of plant evolution, but how these factors interact to influence plant evolution in multispecies communities is still poorly understood. We performed experimental evolution exposing Brassica rapa plants to a combination of

Identification and functional characterisation of a novel N-cyanoamidine neonicotinoid metabolising cytochrome P450, CYP9Q6, from the buff-tailed bumblebee Bombus terrestris [PDF]
, 2019 Recent work has shown that two bumblebee (Bombus terrestris) cytochrome P450s of the CYP9Q subfamily, CYP9Q4 and CYP9Q5, are important biochemical determinants of sensitivity to neonicotinoid insecticides.
