Dispersion of Bumblebee Bombus Semenoviellus Skorikov (Hymenoptera, Apidae) in Poland

open access: yesJournal of Apicultural Science, 2020
The aim of the study is to present all distribution sites of Bombus semenoviellus in Poland reported between 1988 and 2019. The increase of species dispersion was concluded, especially in the central part of the country, as well as the occurrence in the ...

The native bee fauna of the Palouse Prairie (Hymenoptera: Apoidea) [PDF]

open access: yes, 2017
While synoptic collections provide data on the range and general composition of the North American bee fauna, bee communities associated with specific habitats are largely uncharacterized.

Assessing pathogen risk for wild bumblebees (Bombus spp., Apidae) in Canada

open access: yesConservation Science and Practice, EarlyView.
Pathogen spillover poses a significant threat to wild bumble bees (Bombus spp.) in Canada. Our study maps areas of overlap between high conservation priority regions for bumble bees and regions of pathogen spillover risk from managed bees, incorporating uncertainty in pathogen prevalence.

Fluorescent colors in orchid bees (Hymenoptera: Apidae) [PDF]

open access: yesNeotropical Entomology, 2005
The presence of UV-fluorescent pigments is described for the first time in insects. The clear hairs on terga I, III and IV of Eulaema niveofasciata (Friese) are the only ones among several Euglossina species which fluoresce, supporting recent taxonomic studies which suggested that this endemic species of the Atlantic Forest domain and Eulaema ...

The draft genome sequence of the Japanese honey bee, Apis cerana japonica (Hymenoptera: Apidae)

open access: yesEuropean Journal of Entomology, 2018
Honey bees are not only important for honey production but also as pollinators of wild and cultivated plants. The Eastern honeybee (Apis cerana) is more resistant to several pathogens than the Western honeybee (Apis mellifera), and the genomes of two ...

Combined stress from parasites, pesticides and lack of flowers drives bee declines [PDF]

open access: yes, 2015
Bees are subject to numerous pressures in the modern world. The abundance and diversity of flowers has declined, bees are chronically exposed to cocktails of agrochemicals, and they are simultaneously exposed to novel parasites accidentally spread by ...

Are honey bees altering wild plant–bee interactions in reconstructed native habitats? An investigation of summer season effects in row‐crop agroecosystems with prairie strips

open access: yesEcological Entomology, EarlyView.
We investigated the compatibility of beekeeping with pollinator conservation in ‘prairie strips’ a conservation practice integrating native prairie habitat into agricultural environments. At prairie strip sites with and without a honey bee apiary, we analysed plant–bee interactions and bumble bee body conditions to determine the effect of apiaries on ...

Male territorial behaviour of the endemic large carpenter bee, Xylocopa (Koptortosoma) ogasawarensis (Hymenoptera: Apidae), on the oceanic Ogasawara Islands

open access: yesEuropean Journal of Entomology, 2008
The endemic large carpenter bee, Xylocopa (Koptortosoma) ogasawarensis Matsumura (Hymenoptera: Apidae), on the oceanic Ogasawara (Bonin) Islands, located in the northwestern Pacific Ocean, approximately 1000 km south of the Japanese mainland, is a ...

Annual variation across functional traits: The effects of precipitation and land use on four wild bee species

open access: yesEcological Entomology, EarlyView.
We found that a dry active season increased abundance for large bees (Bombus impatiens and Xenoglossa pruinosa), whereas Agapostemon virescens and Ceratina calcarata were more abundant in wet active seasons. A dry year resulted in larger individuals with reduced foraging effort for most bees and communities were relatively more female‐biased.
