The Complex Demographic History and Evolutionary Origin of the Western Honey Bee, Apis Mellifera. [PDF]

open access: yes, 2017
The western honey bee, Apis mellifera, provides critical pollination services to agricultural crops worldwide. However, despite substantial interest and prior investigation, the early evolution and subsequent diversification of this important pollinator ...

Positive selection in cytochrome P450 genes is associated with gonad phenotype and mating strategy in social bees

open access: yesScientific Reports, 2023
The honey bee, Apis mellifera differs from all other social bees in its gonad phenotype and mating strategy. Honey bee queens and drones have tremendously enlarged gonads, and virgin queens mate with several males. In contrast, in all the other bees, the

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.

A SNP assay for assessing diversity in immune genes in the honey bee (Apis mellifera L.)

open access: yesScientific Reports, 2021
With a growing number of parasites and pathogens experiencing large-scale range expansions, monitoring diversity in immune genes of host populations has never been so important because it can inform on the adaptive potential to resist the invaders ...

Specificity Between Lactobacilli And Hymenopteran Hosts Is The Exception Rather Than The Rule [PDF]

open access: yes, 2013
Lactobacilli (Lactobacillales: Lactobacillaceae) are well known for their roles in food fermentation, as probiotics, and in human health, but they can also be dominant members of the microbiota of some species of Hymenoptera (ants, bees, and wasps ...

Rapid evolution of chemosensory receptor genes in a pair of sibling species of orchid bees (Apidae: Euglossini). [PDF]

open access: yes, 2015
BackgroundInsects rely more on chemical signals (semiochemicals) than on any other sensory modality to find, identify, and choose mates. In most insects, pheromone production is typically regulated through biosynthetic pathways, whereas pheromone sensory

Seasonal variation in defense behavior in European and scutellata-hybrid honey bees (Apis mellifera) in Southern California

open access: yesScientific Reports, 2023
Nest defense in the honey bee (Apis mellifera) is a complex collective behavior modulated by various interacting social, environmental, and genetic factors. Scutellata-hybrid (“Africanized”) honey bees are usually considered to be far more defensive than

Identification of africanized honey bee (Hymenoptera: apidae) mitochondrial DNA: validation of a rapid polymerase chain reaction-based assay [PDF]

open access: yes, 2003
Polymerase chain reaction (PCR)-ampliÞed mitochondrialDNA(mtDNA)assays have been used in studies of the Africanization process in neotropical feral and managed honey bee populations.

SNPs selected by information content outperform randomly selected microsatellite loci for delineating genetic identification and introgression in the endangered dark European honeybee (Apis mellifera mellifera) [PDF]

open access: yes, 2016
The honeybee (Apis mellifera) has been threatened by multiple factors including pests and pathogens, pesticidesand loss of locally adapted gene complexes due to replacement and introgression. In western Europe, the geneticintegrity of the native A.
