The poor health status of the Western honey bee, Apis mellifera, compared to its Eastern counterpart, Apis cerana, is remarkable. This has been attributed to lower pathogen prevalence in A. cerana colonies and to their ability to survive infestations with the ectoparasitic mite, Varroa destructor. These properties have been linked to an enhanced removal of dead or unhealthy immature bees by adu...

The mineral, total amino acid, and sterol compositions of pollen collected by Apis mellifera L. were compared with the pollen of a plant consumed by Bombus terrestris (L.): Arbutus unedo L. This plant provides the predominant food resource for the main autumn generation of B. terrestris in southern France. Honey bees also forage on this plant, although only for nectar. The mineral composition o...

A number of image recognition systems have been specifically formulated for the individual recognition of large animals. These programs are versatile and can easily be adapted for the identification of smaller individuals such as insects. The Interactive Individual Identification System, I3S Classic, initially produced for the identification of individual whale sharks was employed to distinguis...

Meiotic recombination is required for proper chromosome assortment, and accordingly, 1-2 chiasmata per chromosome are found in most species. However, observed recombination rates deviate in some cases from neutral expectations between and within genomes and may play an important role in adaptive evolution. One potentially important argument for an adaptive evolution of recombination rates is th...

When vespine wasps, Vespa velutina Lepeletier (Hymenoptera: Vespidae), hawk (capture) bees at their nest entrances alerted and poised guards of Apis cerana cerana F. and Apis mellifera ligustica Spinola (Hymenoptera: Apidae) have average thoracic temperatures slightly above 24° C. Many additional worker bees of A. cerana, but not A. mellifera, are recruited to augment the guard bee cohort and b...

In swarming season, honeybee queens emit two kinds of queen piping signals: tooting and quacking. These signals are considered to be important for swarming, honeybees distinguish between the through differences in their temporal structures. this study, we revealed that species, Apis cerana mellifera, had different The A. consisted almost one long syllable, while mellifera was constructed from s...

Apis mellifera intermissa is the native honeybee subspecies of Algeria. A. m. intermissa occurs in Tunisia, Algeria and Morocco, between the Atlas and the Mediterranean and Atlantic coasts. This bee is very important due to its high ability to adapt to great variations in climatic conditions and due to its preferable cleaning behavior. Here we report the draft genome sequence of this honey bee,...
