Abstract

Apis mellifera

genetic variation

Apis cerana chalkbrood

Ascosphaera apis

chalkbrood

Chalkbrood infection caused by the fungus Ascosphaera apis currently has a significant impact on Australia’s apicultural industry. We investigated the genetic variation of A. apis and colony and apiary level conditions to determine if an emerging, more virulent strain or specific conditions were responsible for the prevalence of the disease. We identified six genetically distinct strains of A. apis, four have been reported elsewhere and two are unique to Australia. Colonies and individual larvae were found to be infected with multiple strains of A. apis, neither individual strains, combinations of strains, or obvious colony or apiary characteristics were found to be predictive of hive infection levels. These results suggest that host genotype plays an important role in colony level resistance to chalkbrood infection in Australia.
