Resumo
Field tests were carried out during the rainy season of 2001/2002 in São Luís de Montes Belos, Goiás, Brazil, to
evaluate the potential of the entomopathogenic fungus, Beauveria bassiana, against peridomestic Triatoma sordida.
An oil-water formulation of the isolate CG 14 (Embrapa) was applied in triatomine infested hen houses of four farms
at a final concentration of 10 6 conidia/cm 2 . Numbers of T. sordida decreased over the next 25 days, after applica-
tion of the fungus, and B. bassiana developed on dead insects in one hen house. A high number of B. bassiana
colonies was detected in substrates collected in treated hen houses 24 h after application of CG 14. In the following
three months the presence of B. bassiana declined to values found before treatment.
