Goat and sheep folks from Alto Mearim and Grajau microregion, State of Maranhao, were examined by inspection and by feeling to collected ectoparasites. The specimens were kept in individual bottles for each host sampled with alcohol 70 degrees GL as preserver liquid. The identification was carried out at Universidade Estadual do Maranhao at the laboratory of parasitology. The ticks were examined in stereomicroscope and identified through Aragao and Fonseca (1961) dicotomic key; the lice were mounted in slides according to Pinto (1938) technique, examined in optic microscope and identified through Tuff (1977) and Furmam and Catts (1977) keys; the fly larvae were examined in stereomicroscope and identified by the morphology of the peritreme, and spiracular slits. In 380 animals sampled, 143 (37,64%) were infested with ectoparasites. The following parasites were identified: Bovicola caprae, Boophilus microplus, larvae of Cochliomya hominivorax (screw-worm) and larvae of Dermatobia hominis (bot fly). Parasitary association was observed only in goats in Grajau and Sitio Novo (louse+tick; louse+bot fly; screw-worm+louse and ticks+louse+screw-worm). The statistic analyses demonstrated that the prevalence of ectoparasites was high in the rainy season (P<0.02).
