The mitochondrial genome of a worker Apis mellifera jemenitica was 16,623 bp. It consisted of 13 protein-coding genes, 22 transfer RNAs, two ribosomal RNAs and a control region. Phylogenetic analyses suggest a close relationship between A. m. jemenitica,

Modelling honey bee colonies in winter using a Keller-Segel model with a sign-changing chemotactic coefficient [PDF]
Thermoregulation in honey bee colonies during winter is thought to be self-organised. We added mortality of individual honey bees to an existing model of thermoregulation to account for elevated losses of bees that are reported worldwide. The aim of analysis is to obtain a better fundamental understanding of the consequences of individual mortality ...

The mitochondrial genome of Apis mellifera simensis (Hymenoptera: Apidae), an Ethiopian honey bee
The complete mitochondrial genome of Apis mellifera simensis was 16,523 bp long. The 13 protein-coding genes, two rRNAs, and 22 tRNAs resembled other Apis mitogenomes. The location of this Apis subspecies in our phylogenetic tree supported the hypothesis

An epidemiological model of viral infections in a Varroa-infested bee colony: the case of a bee-dependent mite population size [PDF]
In recent years the spread of the ectoparasitic mite Varroa destructor has become the most serious threat to worldwide apiculture. In the model presented here we extend the bee population dynamics with mite viral epidemiology examined in an earlier paper by allowing a bee-dependent mite population size.

MSPB: a longitudinal multi-sensor dataset with phenotypic trait measurements from honey bees [PDF]
We present a longitudinal multi-sensor dataset collected from honey bee colonies (Apis mellifera) with rich phenotypic measurements. Data were continuously collected between May-2020 and April-2021 from 53 hives located at two apiaries in Qu\'ebec, Canada. The sensor data included audio features, temperature, and relative humidity.

Melittin promotes dexamethasone in the treatment of adjuvant rheumatoid arthritis in rats
Background: Rheumatoid arthritis (RA) is an erosive-destructive inflammation of the joints, and the chronic, long-term stiffness and deformation induced by RA are some of the symptoms of arthritis that are difficult to treat.

Endophytic fungi are extensive in plant tissues and involved in the defense against stress from harmful microbes. The interaction between pedicel endophytic fungi and nectar yeasts is critical for maintaining nectar homeostasis.

Viral epidemiology of the adult Apis Mellifera infested by the Varroa destructor mite [PDF]
The ectoparasitic mite Varroa destructor has become one of the major worldwide threats for apiculture. Varroa destructor attacks the honey bee Apis mellifera weakening its host by sucking hemolymph. However, the damage to bee colonies is not strictly related to the parasitic action of the mite but it derives, above all, from its action as vector ...
