Chemical Ecology of Bumble Bees
Annual Review of Entomology, 2014Bumble bees are of major importance, ecologically and economically as pollinators in cool and temperate biomes and as model organisms for scientific research. Chemical signals and cues have been shown to play an outstanding role in intraspecific and interspecific communication systems within and outside of a bumble bee colony.

May-month — month of swarming, singing, mating birds — the bumble-bee month — month of the flowering lilac — (and then my own birth-month.) As I jot this paragraph, I am out just after sunrise, and down towards the creek.

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.

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.

Global Trends in Bumble Bee Health
Annual Review of Entomology, 2020Bumble 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, 1993SummaryThe 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, 2002Bumble 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.

Immune defence in bumble-bee offspring
Nature, 2001Immune-challenged vertebrate females transfer specific antibodies to their offspring, but this gratuitous immunity cannot operate in invertebrates. Here we show that constitutive immune defence is enhanced in sexual offspring of the bumble-bee Bombus terrestris L. when the parental colony is immune-challenged.

ALIEN BUMBLE BEE AFFECTS NATIVE PLANT REPRODUCTION THROUGH INTERACTIONS WITH NATIVE BUMBLE BEES
Ecology, 2008The invasive alien bumble bee Bombus terrestris may hinder the reproduction of native plants that have established specialized pollination systems with native bumble bees. To test this hypothesis, we examined the visitation frequency and behavior of native and alien bumble bee species and resultant seed production in Corydalis ambigua, a native plant ...
