Juvenile hormone regulates brain-reproduction tradeoff in bumble bees but not in honey bees.

Hormones and Behavior, 2020
Gonadotropic hormones coordinate processes in diverse tissues regulating animal reproductive physiology and behavior. Juvenile hormone (JH) is the ancient and most common gonadotropin in insects, but not in advanced eusocial honey bees and some ants.

Agricultural field margins provide food and nesting resources to bumble bees (Bombus spp., Hymenoptera: Apidae) in Southwestern Ontario, Canada

Insect Conservation and Diversity, 2020
Bumble bees are declining globally, largely due to habitat loss driven by agricultural intensification. Within agriculturally dominated landscapes, semi‐natural habitats (e.g.

Bumble bee gardeners

Science, 2020
Pollinators Bumble bees rely heavily on pollen resources for essential nutrients as they build their summer colonies. Therefore, we might expect that annual differences in the availability of these resources must simply be tolerated, but Pashalidou et al.

Bumble Bee Culture

Bee World, 2017
Observing the behaviour of others is a quick, low risk way to learn useful information and skills. It should come as no surprise that many animals rely on social learning to help them survive.

Parasites and pathogens associated with native bumble bees (Hymenoptera: Apidae: Bombus spp.) from highlands in Bolivia and Peru

, 2020
Bumble bees of the genus Bombus spp. play a key role as effective pollinators in the biodiversity rich Central Andean region; however, parasites and pathogens may negatively influence their abundance and population numbers.

Global Trends in Bumble Bee Health

Annual Review of Entomology, 2020
Bumble bees ( Bombus) are unusually important pollinators, with approximately 260 wild species native to all biogeographic regions except sub-Saharan Africa, Australia, and New Zealand. As they are vitally important in natural ecosystems and to agricultural food production globally, the increase in reports of declining distribution and abundance over ...

Occupational allergy to bumble bee venom

Clinical & Experimental Allergy, 1993
SummaryThe clinical profile of anaphylactic reactions to bumble bees is described and successful immunotherapy with honey bee venom in seven bumble bee allergic patients is reported. The cause of the high frequency of sensitization to pollen in these patients is discussed.

Recognition of incomplete patterns by bumble bees

Behavioural Processes, 2002
Bumble bees were trained to discriminate between two visual patterns, one of which was rewarding (S+) and one of which was unrewarding (S-). Subsequently, they were tested for discrimination between two non-rewarding patterns: the top halves of the training patterns, the bottom halves or the side halves.
