  • The Dermatobia hominis larvae (Linnaeus Jr., 1781) (Diptera: Cuterebridae) causes a subcutaneous nodular miyasis and brings about irreversible perforation on skin, which damages the leather and therefore lowers its price for commercialization. The main purpose of the present work is to establish the larva distribution in cattle corporal area and also to define the infestation according to sex, age and color of skin. This survey was elaborated covering 8124 cattle slaughted in a slaughterhouse in Nilópolis city, Rio de Janeiro state, Brazil, with the intention of to identify larvae localization and distribution. The leather surface was divided into four regions: I (left anterior quadrant), II (right anterior quadrant), III (left posterior quadrant), IV (right posterior quadrant); the skin color was also registered. 84,8% leather skin examined were totally free from parasite. The incidence of parasited on region I was significantly larger: 33.4% (3029), on region II 30.9% (2796), on region III 20% (1813), on region IV 15.7% (1423). As to sex frequency the females presented more parasites 16.7% (342) than the males 14.7% (894). The adults were more vulnerable (15.4%) than the younger ones (12.1%). The parasite appeared more in black skins (18.1%), black and red (15.2%), black and white (15.3%), red (15.2%), spotted (13.2%), gray (11.8%).
