"The BEE DOC comprises a network of eleven partners from honeybee pathology, chemistry, genetics and apicultural extension aiming to improve colony helath of honeybees. The BEE DOC will empirically and experimentally fill knowledge gaps in honey bee pest and diseases, including the 'colony collapse disorder' and quantify the impact of ineractions between parasites, pathogens and pesticides on honey bee mortality. Specifically BEE DOC will show for two model parasites (Nosema and Varroa mites), three model viruses (Deformed Wing Virus, Black Queen Cell Virus, Israel Acute Paralysis Virus) and two model pestcides (fipronil, τ-fluvalinate) how interactions affect individual bees and colonies in different European areas. The BEE DOC will use transcriptome anayses to explore host-pathogen-pesticide interaction and identify novel genes for disease resistance. The BEE DOC will specifically address sublethal and chronic exposure to pesticides and screen how apicultural practices affect colony health. The BEE DOC will develop novel diagnostic screening methods and develop sustainable concepts for disease prevention using novel treatments and selection tools for resitant stock. The BEE DOC will be linked to various national and international ongoing European, North-, and Latin-American colony health monitoring and research programs, which will not only ensure a pan European but also a global visibility and the transfer of results to a world wide community of beekeepers."
