Honey bee genotypes and the environment [PDF]

open access: yes, 2014
Although knowledge about honey bee geographic and genetic diversity has increased tremendously in recent decades (Meixner et al., 2013), the adaptation of honey bees to their local environment has not been well studied.

Getting more than a fair share: nutrition of worker larvae related to social parasitism in the Cape honey bee Apis mellifera capensis [PDF]

open access: yes, 2002
Besides activation of ovaries and thelytokous reproduction of Cape workers, larval nutrition is an important aspect in parasitism of the African honey bee.

Differentiation of argentine propolis from different species of bees and geographical origins by UV spectroscopy and chemometric analysis [PDF]

open access: yes, 2018
Bees collect vegetal resins that they mix with their wax and mechanical impurities to elaborate propolis, whose chemical composition is complex and variable depending on botanical/geographical origin, type of bee, time of year when it was produced and ...

Introgression in native populations of Apis mellifera mellifera L: implications for conservation [PDF]

open access: yesJournal of Insect Conservation, 2018
Hybridisation and introgression can have negative impacts on regional biodiversity through the potential erosion of locally adapted lineages. The honey bee (Apis mellifera L.) occurs in twenty-seven subspecies across Europe, is an extremely economically important insect, yet threatened by multifarious impacts.

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]

open access: yes, 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 ...

Synthesis of wax in the honeybee (Apis mellifera L.) [PDF]

open access: yesJournal of Insect Physiology, 1964
Newly emerged honeybee workers were fed during 1 or 2 weeks with sucrose containing either heavy water, sodium acetate with deuterium, sodium acetate-1-14C, or uniformly labelled glucose-14C. The various lipid fractions were isolated in order to investigate the origin of the secreted wax components. In feeding acetate with deuterium or 14C the isolated

Haplotypes of the tRNAleu-COII mtDNA Region in Russian Apis mellifera Populations

open access: yesAnimals, 2023
Analysis of the mtDNA tRNAleu-COII locus is a widely used tool to establish belonging to a particular evolutionary lineage of Apis mellifera L. (lineages A, M, C, O, and Y).

The genomes of two key bumblebee species with primitive eusocial organization [PDF]

open access: yes, 2015
Background: The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies.
