Resumo
To survey and to characterize entomopathogenic fungi as natural
enemies of mosquitoes in Central Brazil.
Methods and Results: Tolypocladium cylindrosporum (Hypocreales, Ophio cordycipitaceae) was isolated for the first time in South America by using Aedes
aegypti (Diptera, Culicidae) as sentinel larvae in a stagnant mosquito breeding
site in a secondary tropical forest. Two isolates were morphologically and
molecularly identified, and their activity tested against A. aegypti eggs, larvae and
adults.
Conclusions: Findings emphasize the importance of T. cylindrosporum as a
natural fungal antagonist of mosquitoes.
Significance and Impact of the Study: Both isolates affected larvae and adults
but were less effective against eggs; both have potential for development as a
mycoinsecticide especially against larvae of A. aegypti the main vector of
dengue, chikungunya, Zika and urban yellow fever.
