Tesovnik Tanja, Zorc Minja, Ristanić Marko, Glavinić Uroš, Stevanović Jevrosima, Narat Mojca, Stanimirović Zoran (2019) Exposure of honey bee larvae to thiamethoxam and its interaction with Nosema ceranae infection in adult honey bees, Environmental Pollution, DOI: 10.1016/j.envpol.2019.113443 Abstract During their lifetime honey bees (Apis mellifera) rarely experience optimal conditions. Sometimes, a simultaneous action of multiple…

PhD position “Conservation physiology in wild bees” –...

Most of studies on wild bee decline have focused on species richness and distribution patterns through large (national to continental) scales. However, those patterns (species range contractions and diversity erosion) depict the outcome of extinction processes. Conservation biologists urgently need to identify alternative ecological parameters and measurements that are liable to reveal population trends before…

The effect of diet types on some quality...

Slobodan Dolasevic, Jevrosima Stevanovic, Nevenka Aleksic, Uros Glavinic, Nebojsa Deletic, Mica Mladenovic & Zoran Stanimirovic The influence of various diets on the quality of Apis mellifera queens was assessed. Colonies intended for queen cell production were assigned to four groups fed on (1) sugar-only, (2) mix of sugar, honey and fresh pollen, (3) sugar and pollen substitute…

The Effect of Diet on the Composition and...

Honey proteins are essential bee nutrients and antimicrobials that protect honey from microbial spoilage. The majority of the honey proteome includes bee-secreted peptides and proteins, produced in specialised glands; however, bees need to forage actively for nitrogen sources and other basic elements of protein synthesis. Nectar and pollen of dierent origins can vary significantly in…

The rise and fall of major royal jelly...

The genome of the western honeybee (Apis mellifera) harbors nine transcribed major royal jelly protein genes (mrjp1‐9) which originate from a single‐copy precursor via gene duplication. The first MRJP was identified in royal jelly, a secretion of the bees’ hypopharyngeal glands that is used by young worker bees, called nurses, to feed developing larvae. Thus,…
