Metarhizium anisopliae blastospores are highly virulent to adult Aedes aegypti, an important arbovirus vector.

Background: The use of entomopathogenic fungi (EPF) for the control of adult mosquitoes is a promising alternative to synthetic insecticides. Previous studies have only evaluated conidiospores against adult mosquitoes. However, blastospores, which are highly virulent against mosquito larvae and pupae, could also be effective against adults.
