Testing microbial pest control products in bees, a comparative study on different bee species and their interaction with two representative microorganisms

Background: The evaluation of the impact of pesticides on non-target species, like bees, is a crucial factor in registration procedures. Therefore, standardized test procedures have been developed on OECD level assessing the effects of chemicals on honey bees or bumble bees. Unfortunately, these protocols cannot directly be adapted for testing products that contain microorganisms. Interest…

Standard methods for European foulbrood research 2.0

European foulbrood (EFB) is a severe bacterial honey bee brood disease caused by the Grampositive bacterium Melissocccus plutonius. The disease is widely distributed worldwide, and is an increasing problem in some areas. Although the causative agent of EFB was described almost a century ago, many basic aspects of its pathogenesis are still unknown. Earlier studies…

The effect of major abiotic stressors on honey bee (Apis mellifera L.) queens and potential impact on their progeny

Queen health and quality play a significant role in the survival, expansion, and productivity of honey bee colonies. Nevertheless, modern beekeeping practices, intensified agriculture, and climate change can leave queens vulnerable to diverse stressors. These stressors can exert a negative impact on queens, resulting in a range of morphological and physiological abnormalities. The repercussions of…
