Abstract

The effect of azadirachtin was investigated using three different fresh isolates of Trypanosoma cruzi and five different triatomine species which were infected as third-instar larvae. The two T. cruzi strains which originated from sylvatic Triatoma vitticeps showed a high prevalence after the molt to the fifth instar in Panstrongylus megistus and Rhodnius neglectus and a low prevalence in Triatoma infestans and Rhodnius robustus. The third T. cruzi strain originating from a patient in Piauí showed a high prevalence in P. megistus, R. neglectus and T. infestans and a low prevalence in Triatoma sordida. Feeding the infected fifth instars with azadirachtin-supplemented blood (1 μg/ml) resulted 20 days later in some parasite/vector combinations in an increase, in others a decrease or an unchanged number of T. cruzi in comparison to bugs fed with unsupplemented blood.
