Cuckoo bumblebees (subgenus Psithyrus) are social parasites in colonies of their host bumblebee species (Bombus). In spring, parasitic females awaken from hibernation and start searching for established host nests. Some Psithyrus species are specialized on one host species, whereas generalists parasitize several species. In previous investigations, nest-marking signals of the bumblebee hosts have been shown to play a role in host recognition and discrimination between host and nonhost. We… Expand
A method for year-round rearing of cuckoo bumblebees (Hymenoptera: Apoidea: Bombus subgenus Psithyrus)
TLDR
A simple method for rearing cuckoo bumblebees (Bombus subgenus Psithyrus) in the laboratory enables a year-round and mass breeding of Psith Cyrus species to facilitate studies of these rare species. Expand
Specific recognition of reproductive parasite workers by nest-entrance guards in the bumble bee Bombus terrestris
TLDR
Chemical analysis revealed that the cuticular chemical profiles of workers encode information about both their colony membership and their current fertility, therefore providing potential recognition cues for a suitable adjustment of the guards’ defensive decisions, and provides a first piece of empirical evidence supporting the hypothesis that an adapted defensive strategy against worker reproductive parasitism exists in B. terrestris colonies. Expand
Nest wax triggers worker reproduction in the bumblebee Bombus terrestris
TLDR
It is suggested that wax scent enables workers to time their reproduction by providing essential information concerning the social condition of the colony by changing the patterns and amounts of cuticular lipids change considerably during colony development. Expand
The chemical basis of host nest detection and chemical integration in a cuckoo paper wasp
TLDR
It is demonstrated that CHCs are fundamental in both steps of the host exploitation process, thus confirming their primary role in social insect life and consequently in social parasite–host interactions. Expand
Ecology and Evolution of Cuckoo Bumble Bees
Abstract Most social insect lineages contain socially parasitic cheater species that, rather than produce their own workers, infiltrate the nests of closely related social species and force the hostsExpand
Bumblebee-mediated pollination of English populations of the Military Orchid (Orchis militaris): its possible relevance to functional morphology, life history and climate change
TLDR
It is suggested that bumblebees (Bombus spp.) may have become the primary pollinators of the orchid at the site and models of pollination ecology should consider the caste and life history of the relevant insect. Expand
Wax Lipids Signal Nest Identity in Bumblebee Colonies
TLDR
The findings suggest that wax emits characteristic olfactory profiles that are used by workers to recognize their colony, and that bumblebees were able to discriminate between wax scents from their own and a foreign colony. Expand
Chemical ecology of bumble bees.
TLDR
The development of new and more sensitive analytical tools and improvements in sociogenetic methods significantly enhanced knowledge about chemical compounds that mediate the regulation of reproduction in the social phase of colony development, about the interactions between host bumble bees and their social parasites, about pheromones involved in mating behavior, as well as about the importance of signals, cues and context-dependent learning in foraging behavior. Expand
Reproductive Dominance Strategies in Insect Social Parasites
TLDR
This review compares socially parasitic insect lineages to find general trends and build a hypothetical framework for the means by which social parasites achieve reproductive dominance, and highlights how host social organization and social parasite life history traits may impact the way they achieve reproductive supremacy. Expand
Drifting behaviour as an alternative reproductive strategy for social insect workers
TLDR
It is shown in the bumblebee Bombus terrestris that drifting is a distinct strategy by which fertile workers circumvent competition in their nest and reproduce in foreign colonies, and shows that the drifting of fertile workers reflects complex decision-making processes associated with in-nest reproductive competition.

The role of trail pheromones in host nest recognition of the social parasitic bumblebees Bombus bohemicus and Bombus rupestris (Hymenoptera: Apidae)
TLDR
The results show that volatile signals enable parasite females to discriminate between potential host species, and intercolonial differences within the single species are found. Expand
Do social parasitic bumblebees use chemical weapons? (Hymenoptera, Apidae)
TLDR
Dodecyl acetate is the first repellent allomone identified in bumblebees, used to repel attacking B. hypnorum workers during nest usurpation and subsequently during colony development. Expand
Chemical ecology involved in invasion success of the cuckoo bumblebee Psithyrus vestalis and in survival of workers of its host Bombus terrestris
TLDR
In bumblebees all species of the subgenus Psithyrus are social parasites in the nests of their Bombus hosts, and the Psith Cyrus female clearly maintains reproductive dominance utilizing differences in the odour bouquets as criteria for killing workers that compete for reproduction. Expand
Host-parasite relationships in six species ofSphecodes bees and their halictid hosts: Nest intrusion, intranidal behavior, and Dufour's gland volatiles (Hymenoptera: Halictidae)
TLDR
Comparisons of whole patterns and quantitative comparisons considering the predominant hydrocarbons common to both host and parasite contradict the hypothesis of chemical mimetism, a mechanism supposed to permit parasite intrusion by qualitatively similar odor bouquets in host and parasites females. Expand
Fertility signals in the bumblebee Bombus terrestris (Hymenoptera: Apidae)
TLDR
Egg-laying females contained higher total amounts of chemical compounds and of relative proportions of wax-type esters and aldehydes than nest-searching queens and workers before the competition point, suggesting that these compounds may have a function as a fertility signal present in queens and Workers. Expand
Host recognition and the study of a chemical basis for attraction by cuckoo bumble bees (Hymenoptera: Apidae)
TLDR
Parasites of both species were capable of distinguishing host bees from other bumble bee species using chemical cues contained within extracts, and among extracts of several body parts presented to parasites, the abdomen produced the greatest behavioral response. Expand
Caste- and colony-specific chemical signals on eggs of the bumble bee, Bombus terrestris L. (Hymenoptera: Apidae)
TLDR
In the bumble bee, females very likely mark eggs with excretions of Dufour’s gland, however, other glands may also be involved and the volatile patterns were found to be colony-specific. Expand
Suppression of ovarian development of Bombus terrestris workers by B. terrestris queens, Psithyrus vestalis and Psithyrus bohemicus females
TLDR
Ovarian development inhibition by P. bohemicus was not statistically different both from the positive and the negative control, indicating that this non-specific parasite is able to affect the ovarian development of workers, but not to the same extent as the queens of the same species or the females of the specific parasite. Expand
Profiles of cuticular hydrocarbons mediate male mate choice and sexual isolation between hybridising Chrysochus (Coleoptera: Chrysomelidae)
TLDR
It is established that CHCs influence sexual isolation in this system, and the evolutionary lability of these cues can be assessed, which will inform both the understanding of speciation, and of the conditions under which the chemical signaling systems that influence mate choice in insects can evolve.

TLDR
In seven parasitic Sphecodes species, the specificity of Dufour's gland morphology and volatile secretions was studied, resulting in an arrangement of the species corresponding to the classification according to the gland morphology. Expand
