Rapid transformation of traditional beekeeping and colony marketing erode genetic differentiation in Apis mellifera simensis, Ethiopia

Apidologie, 2022
Subsistent beekeeping has been an established tradition in Tigray, northern Ethiopia. In the last two decades, extension efforts tried to transform it into improved apiculture, which led to development of colony marketing.

An RNA interference biopesticide reduces reproduction of the honey bee parasite Varroa destructor by down‐regulating embryo development pathways

Pest Management Science, EarlyView.
Varroa destructor mites exposed to dsRNA specific in sequence to a V. destructor calmodulin gene significantly effected gene expression of adult female mites sampled 5 days after entering a honey bee brood cell to reproduce. Significantly down‐regulated genes included Calmodulin and were associated with calcium ion binding and embryo developmental ...

Knockout of a single Pax6 gene (toy but not ey) leads to compound eye deficiency and small head in honeybees

Communications Biology
The compound eyes are crucial to honeybees, playing pivotal roles in color recognition, orientation, localization, and navigation processes. The development of compound eyes is primarily mastered by an evolutionarily conserved transcription factor Pax6 ...

The Standardization of the Honeybee Colonies Evaluation Methodology, with Application in Honeybee Breeding Programs, in Romanian Conditions

Scientific Papers Animal Science and Biotechnologies, 2023
It is well known that breeding is based on phenotypic and behavioural performance assessed at the level of each honeybee colony. By selection, the genes responsible for the desired characters have to be favoured, by evaluation and classification of all ...

Field size as a determinant of common vole population density

Pest Management Science, EarlyView.
Population densities of the common vole, an agricultural pest, increase nonlinearly with forage field size, especially in fields below 20 ha. Reducing the field size may help limit crop damage in farmland. Abstract BACKGROUND Environmental heterogeneity in agricultural landscapes is a key driver of biodiversity and ecological processes, yet its role in
