Two strains, Penicillium corylophilum and Aspergillus giganteus , of the most frequent species found in a survey of triatomines, were used for bioassays in the second and fourth nymphs stage of Triatoma infestans and Panstrongylus megistus . Two procedures, bite and pulverization, were used and compared. A. giganteus was most effective, causing mortality in at least 50% of the nymphs of the two species tested with exception of the nymphs of the fourth stage of P. megistus . Variation in entomopathogenic capacity of the fungal species were observed in the experiments. The two procedures used proved effective.
