Vectors of Dermatobia hominis, Linnaeus Jr., 1781 (Diptera: Cuterebridae ) in the Uberaba Area, Minas Gerais, Brazil

Abstract

Several flies in the literature were described as carriers of eggs of Dermatobia hominis. With the purpose of identifying these flies in the Uberaba area, Minas Gerais, from July, 1325 to August, 1985 trapping of flies was carried out with "McGoon" traps, using calves about six months of age as live baits. Three traps were set in different places: close to the stables, in the open field and inside the bushwood. Day trapping was made fortnigntly, and night trapping bimonthly. A total of 48,252 specimens belonging to 23 families of flies were trapped, among which predominated Sarccphagidae and Muscidae, respectively 24,252 and 21,607 ipsects. Fourteen of these were carriers of Dermatobia hominis eggs, respectively 50% Musca domestica, 28,56% Sarcophagula (Sarcophagidae), 14.30 Stomoxys calcitrans (Muscidae) and 7.14% Fannia sp (Fanniidae). Except for one oviposition, all the others were found on one side of the carrier's abdomen, under its wing. The number of eggs carried by each vector ranged from 10 to 52.
