From June 1995 to May 1996, 49,010 insects were captured in the municipality of Pedro Leopoldo, MG, Brazil, using the Magoom's trap. Ten orders were identified and 95.73% of them belong to the order Diptera. Three families, Sepsidae, Syrphidae, and Culicidae, represented 24.65%, 18.53%, and 17.64% respectively, of 46,915 diptera trapped. The bush contributed with the highest number of trapped insects (43,99%) when comparsa with stable or pasture. The biological vectors of D. hominis (with adhered, eggs), in order of prevalence, were Fannia spp, Musca domestica, Stomoxys calcitrans, Synthesiomyia nudiseta, Ophira sp. This is the first identification of the genus Ophira sp. as biological vector of D. hominis. The genus Fannia was found to be the most important biological vector of D. hominis in Pedro Leopoldo, MG, Brazil, because of its high frequency and distribution in the three environment conditions searched.
