Intracolonial genetic variability in honeybee larval resistance to the chalkbrood and American foulbrood parasites

摘要: The origin of multiple mating queens in social Hymenoptera is a widely debated topic evolutionary biology. One the hypotheses that genetic variability would benefit colony by increasing its resistance to parasites through various mechanisms. among predictions this hypothesis different patrilines within species should be independent, as result independent gene-for-gene interactions with each parasite. To test aspect hypothesis, two honeybee colonies (Apis mellifera) were infected fungus Ascosphaera apis and both A. American foulbrood bacterium Paenibacillus larvae. Patrilines found vary larvae all four colonies, but similar variation was not P. Common pathogens detected. This study supports polyandry insects could have originated an adaptation decrease impact diseases.
