    Dictionary entry overview: What does Bombus mean? • BOMBUS (noun) The noun BOMBUS has 1 sense. 1. bumblebees Familiarity information: BOMBUS used as a noun is very rare. Comprising nearly 20% of all bumble bees, the subgenus Pyrobombus is distributed across diverse habitats in the Northern Hemisphere and exhibits considerable morphological and behavioural variation relative to other subgenera. Its size and variation have led to questions concerning its monophyly and intrasubgeneric relationships, but too few known morphological synapomorphies and insufficient Cited by:

A bumblebee (or bumble bee, bumble-bee, or humble-bee) is any of over species in the genus Bombus, part of Apidae, one of the bee families.

This genus is the only extant group in the tribe Bombini, though a few extinct related genera (e.g., Calyptapis) are known from are found primarily in higher altitudes or latitudes in the Northern Hemisphere, although they are also found Class: Insecta.

Until recently, the 29 species of Psithyrus were considered to constitute a separate genus. They are a specialized lineage which has lost the ability to collect pollen and to rear their brood. They have lost the worker caste and produce only sexuals, male and Class: Insecta. The most important epigenetic factors which are able to influence sexual differentiation in the animal kingdom are hormones, temperature and parasites.

Whereas in the first of these factors we are Cited by: Bombus occidentalis is most easily distinguished from other Bombus species based on hair coloration.

Note, however, that coloration in this species can be highly variable (Thorp et al. ), and a total of twelve female and twelve male color forms have been described (Franklin ).

The tree bumblebee or new garden bumblebee (Bombus hypnorum) is a species of bumblebee common in the European continent and parts of the start of the twenty-first century, it has spread to the United Kingdom and bumblebees prefer habitats that others do not, allowing them to pollinate flowers in areas that many other species do not get : Apidae.

Caste differentiation in bumblebees (Bombus Latr.:Hym.) I. — The determination of female sizeCited by: 1. Background. In colonies of eusocial insects, one or a small number of females (queens) dominate the reproduction of the group, whereas the other females (workers) remain (mostly) sterile [].Proximate mechanisms that regulate this reproductive dominance include aggression and pheromones [2–4].It has been hypothesized that aggression originally mediated this conflict in the ancestral state Cited by: Bombus are primarily found in temperate climates and are particularly important pollinators in alpine and arctic environments.

There is a subgenus of Bombus called Psithyrus that are social parasites on other Bombus species. A Psithyrus queen enters the nest of a non-parasitic Bombus and kills the queen.

To determine whether ecdysteroids are associated with reproductive division of labor in Bombus terrestris, we measured their levels in hemolymph and ovaries of queens and heading colonies had large active ovaries with high ecdysteroid content, whereas virgin gynes and mated queens before and after diapause had undeveloped ovaries with low ecdysteroid by:   Many species of bumble bees (Hymenoptera: Apidae: Bombus Latreille) are declining throughout their ranges in North America, yet detecting population trends can be difficult when historical survey data are lacking.

In the present study, contemporary data is compared to a survey to detect changes in bumble bee distributions throughout Arkansas. Introduction. Marking pheromones of bumblebee and cuckoo bumblebee males are produced by the cephalic part of the male’s labial gland (Kullenberg et al., ).During the premating behaviour, males scent-mark their territories to attract conspecific females for mating (Bergman, ).Although three different premating strategies are known in the genus Bombus (bumblebees, Lloyd, Cited by:.
