Contests mediate access to reproductive opportunities in almost all species of animals. An important aspect of the evolution of contests is the reduction of the costs incurred during intra-specific encounters to a minimum. However, escalated fights are commonly lethal in some species like the honeybee, Apis mellifera. By experimentally reducing honeybee queens' fighting abilities, we demonstrat...

Here, we report the first draft genome sequence of Lactobacillus kunkeei strain MP2, isolated from a Chilean honeybee gut. The sequenced genome has a total size of 1.58 Mb distributed into 44 contigs and 1,356 protein-coding sequences.

The present work aimed to reveal morphological characteristics of worker honeybee (Apis mellifera) wings and demonstrate the function of resilin on camber changes during flapping flight. Detailed morphological investigation of the wings showed that different surface characteristics appear on the dorsal and ventral side of the honeybee wings and the linking structure connecting the forewing and ...

Zbog povećanih gubitaka pčelinjih zajednica, potražnja za njima raste iz godine u godinu. Kako bi nadoknadili izgubljene pčelinje zajednice ili povećali veličinu pčelinjaka, pčelari moraju kupiti nove ih mogu sami proizvesti tijekom sezone. Cilj ovoga rada bio je ispitati tehnološku i ekonomsku učinkovitost triju različitih metoda proizvodnje zajednica: korištenjem jednoga, dvaju četiriju okvir...

Apis mellifera filamentous virus (AmFV) is a large double stranded DNA virus of honey bees, but its relationship with other parasites and prevalence are poorly known. We analyzed individual honey bees from three colonies at different times post emergence in order to monitor the dynamics of the AmFV gut colonization under natural conditions. Prevalence and loads of microsporidia and trypanosomes...
