Chalkbrood (Ascosphaera apis) and some other fungi associated with Africanized honey bees (Apis mellifera) in Costa Rica



Chalkbrood (Ascosphaera apis) and some other fungi associated with Africanized honey bees (Apis mellifera) in Costa Rica



Journal of Apicultural Research 43(4): 187-188



The presence of Ascosphaera apis and other fungi in Africanized honey bee (AHB) colonies in San Jose, Costa Rica, was evaluated in October Isolates obtained from larvae and pupae were cultured in petri dishes containing agar-peptone media. It was shown that Ascosphaera apis was the most commonly isolated fungi, followed by Penicillium spp., while Beauveria and Cladosporium spp. were less frequently isolated. The mycelia, spores and growth of the fungal colonies are described.
