Research Project

"Pathogen spill-over between pollinators: directionality and impact on biodiversity"

Bees are very important pollinators for wild plants and crops. Around 80 % of our crops are dependent on the ecosystem service of pollination and therefore bees are essential for the security of food supply. It has been shown that the presence of wild insects increase the crop yield in comparison to pollination only with honey bees (Garibaldi et al. 2013). But there is considerable evidence that wild bees are declining (Bartomeus et al. 2013, Carvalheiro et al. 2013, Biesmeijer et al. 2006). Pathogens that are till now linked with honeybees are talked about as one out of many possible reasons for declines. It was shown by Fürst et al. (2014) that wild bees and honeybees collected in the same regions of Great Britain contained the same strain of Deforming Wing Virus, a major honey bee pathogen. So it is not only that honeybee viruses are present in wild bees, there is evidence of ongoing or recent transmission of viral diseases between managed and wild bee populations. But there is little knowledge about the main direction of spread of pathogens between pollinator genera. The aim of my project is to investigate the directionality of virus transmission between different bee species and gain a better understanding of the virulence of different RNA-viruses in wild bee species.
