When African and European Lineages Meet: The Genetic Landscape of Honey Bees in Argentina
Using a 272‐SNP panel, we explored how Africanized (AHB) and European (EHB) honeybee populations interact across Argentina's diverse landscapes. A clear latitudinal pattern in Africanization, with an interesting inverse relationship between African (A) and European (C) ancestry.

Performance of two honey bee subspecies during harsh weather and Acacia gerrardii nectar-rich flow
Both climatic factors and bee forage characteristics affect the population size and productivity of honey bee colonies. To our knowledge, no scientific investigation has as yet considered the potential effect of nectar-rich bee forage exposed to drastic ...

In Vitro and In Vivo Effect of Amitraz on Honey Bee Drone Sperm Quality
ABSTRACT Honey bee hive infestation by the ectoparasitic mite, Varroa destructor, has been a major cause of declining populations. Treating such infestations is important for sustainability. Knowledge about the sub‐lethal effects of commonly used acaricides on drone reproductive health, particularly sperm quality, is limited. The effect of in vitro and

Heritability of grooming behaviour in grey honey bees (Apis mellifera Carnica) [PDF]
Grooming behaviour is considered an important defensive mechanism of honey bees against Varroa mites. The aim of this study was to reveal whether grooming behaviour is a useful criterion in breeding of Varroa-tolerant bees. To obtain a reliable evaluation the environmental influences were excluded.

Biosynthesis of the fatty acid components of the Apis mellifera mandibular gland pheromones takes place in a stepwise manner. Differential gene expression in the mandibular gland tissue of workers from two subspecies of African honey bees with differing reproductive potentials and at two age groups was investigated.

In 2019, a joint eight-variant model was published in which eight single nucleotide polymorphisms (SNPs) in seven Apis mellifera genes were associated with Varroa destructor drone brood resistance (DBR, i.e. mite non-reproduction in drone brood). As this

Land Use and Season Interactively Affect Honeybee (Apis mellifera) Body Size and Fat Stores
Habitat fragmentation and loss due to anthropogenic activities have impacted the foraging success of many animals, including pollinators. In this study, we found that summer honeybees in urban and mixed habitats were smaller and had greater wing wear but had larger fat stores compared to those in agricultural areas, where fat stores dropped during the ...
