INFESTAÇÃO ARTIFICIAL E DESENVOLVIMENTO LARVAL DE Dermatobia hominis (L. Jr., 1781) (Diptera: Cuterebridae) EM SUÍNOS E EQUINOS / ARTIFICIAL INFESTATION AND LARVAL DEVELOPMENT OF Dermatobia hominis (L. Jr., 1781) (DIPTERA: CUTEREBRIDAE) IN SWINES AND HORS

Abstract

Dermatobia hominis is a fly whose vvonns cause myiasis cutaneous furuncular in domestic and wild animals, besides sponging humans. It is an endemic species of the Neotropical area, causing damages mainly to cattle and economy losses, due to hide price devaluation and panisitosis treatment costs. Third instar larvae of D. hominis were collected from slaughtered cattle skins and taken to the laboratoiy. After emergence the adult larvae were transferred to wooden fie: with a screen, were the flies used as vectors were also placed. The removal of the vectors carriers of masses of worm fly eggs was performed daily. The firms instar larvae were them removed with a brush and infested on 4 swine (14 larvae) and 16 horses (2(} larvae). The development of the artificially - infested larvae on the swine lasted for 44 days, on the average, while the larvae that deft the swine remained in the form of pupae for 55 days, on the average. No D. hominis larvae development occurred on any of the infected horses.
