18.104.22.168. Biological diagnosis
Identification of the vegetative stages of the fungus can be done by a mating test with two reference strains (AFSEF 7405 and ARSEF 7406). Production of spore cysts with one of the reference strains would prove the identify of A. apis mating. The mating test is described under paragraph 22.214.171.124. Production and quality of inoculums.
