Bumble Bees (Hymenoptera: Apidae) of Montana [PDF]
Annals of the Entomological Society of America, 2017 Montana supports a diverse assemblage of bumble bees (Bombus Latreille) due to its size, landscape diversity, and location at the junction of known geographic ranges of North American species. We compiled the first inventory of Bombus species in Montana, using records from 25 natural history collections and labs engaged in bee research, collected over ...

Pollenkitt is associated with the collectability of Malvoideae pollen for corbiculate bees
Journal of Pollination Ecology, 2023 Pollen grains of Malvoideae (Malvaceae) which corbiculate bees cannot collect constitute a floral filter that excludes pollen-collecting bumble bees and honey bees from exploiting pollen resources.

Tragedy of the commons in Melipona bees [PDF]
, 2004 In human society selfish use of common resources can lead to disaster, a situation known as the ‘tragedy of the commons’ (TOC). Although a TOC is usually prevented by coercion, theory predicts that close kinship ties can also favour reduced ...

More than fruity scents: Pollination biology, scent, and spectral reflectance of Annonaceae species
Plant Species Biology, EarlyView.We characterised the floral visual and olfactory cues of numerous Annonaceae species and reported their pollinators. We further assessed the olfactory space of most Annonaceae species available in the literature. Abstract The family Annonaceae possesses a broad array of floral phenotypes and pollination specializations, and are important in the plant ...

Towards integrated control of varroa: effect of variation in hygienic behaviour among honey bee colonies on mite population increase and deformed wing virus incidence [PDF]
, 2014 Hygienic behaviour in the honey bee, Apis mellifera, is the uncapping and removal of dead, diseased or infected brood from sealed cells by worker bees. We determined the effect of hygienic behaviour on varroa population growth and incidence of deformed ...

The transformer gene controls sexual development in Drosophila suzukii
Insect Science, EarlyView.The transformer gene plays a key role in the genetic pathway for sexual development in Drosophila suzukii Abstract The genetic network of sex determination in the model organism Drosophila melanogaster was investigated in great detail. Such knowledge not only advances our understanding of the evolution and regulation of sexual dimorphism in insects ...

Xylocopa valga Gerst. (Hymenoptera: Apidae) in Poland
Forest Research Papers, 2016 Abstract In this article, we review the distribution and new data on the occurrence of Xylocopa valga Gerst. (Hymenoptera: Apidae) in Poland. This is also the first report of X. valga occurring in the Białowieża Forest, where it was captured visiting flowers of Lychnis flos-cuculi L.

Ecological impact and population status of non-native bees in a Brazilian urban environment
Revista Brasileira de EntomologiaThe introduction of species is an important global threat to native ecosystems and yet little is known about invasion risks of non-native bees. Moreover, urbanization is increasing rapidly around the world with impact on the bee fauna.
