Detection and quantification of Melissococcus plutonius in honey bee workers exposed to European foulbrood in Czechia through conventional PCR, qPCR, and barcode sequencing

Melissococcus plutonius is the causative agent of European foulbrood (EFB), an important bacterial disease of honey bee larvae, and various methods have been developed for the detection of this disease. Adult bees are not affected but spread M. plutonius among beehives and serve as a diagnostic tool to detect EFB. Melissococcus plutonius detection based on…

Exposure of honey bee larvae to thiamethoxam and its interaction with Nosema ceranae infection in adult honey bees

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” – INRA Avignon (France)

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…
