[h=3]Abstract[/h]Explanations for the evolution of multiple mating by social insect (particularly honey bee) queens have been frequently sought. An important hypothesis is that multiple mating is adaptive because it increases intracolonial genetic diversity and thereby reduces the likelihood that parasites or pathogens will catastrophically infect a colony. We tested one assumption of this model: that honey bee worker patrilines should differ in disease resistance. We used American foulbrood (caused by the bacterium Paenibacillus larvae) as a model pathogen. We found that patrilines within colonies do indeed vary in their resistance to this disease.
