Sheep production used to be a predominantly family activity in the state of Sao Paulo (Brazil), but it began to become a commercial activity in the past decade. Thus, information about the ectoparasites existing in sheep flocks has become necessary. The present data were obtained by means of questionnaires sent to all sheep breeders belonging to the 'Associacao Paulista de Criadores de Ovinos' (ASPACO; Sao Paulo State Association of Sheep Breeders). Response reliability was tested by means of random visits paid to 10.6% of the respondents. Most of the properties (89.5%) reported the presence of one or more ectoparasites. Screw-worm (Cochliomyia hominivorax) was the most frequent ectoparasite (72.5%), followed by bot fly larvae (Dermatobia hominis, 45.0%), ticks (Amblyomma cajennense) and Boophilus microplus, 31.3%) and finally lice (Damalinia ovis, 13.8%). Combined infestations also occurred, the most common one being screw-worm with bot fly larvae (36.0%) followed by bot fly larvae with ticks (13.9%), screw-worm with ticks (9.3%), bot fly larvae with lice (6.9%), and ticks with lice (5.0%). The most common triple combination was screw-worm, bot fly larvae and ticks (12.8%). Breeds raised for meat or wool were attacked by bot fly larvae and ticks more often than other breeds. Lice were only absent from animals of indigenous breeds. The relationships among these ectoparasites are discussed in terms of sheep breeds, flock size, seasonality and the ectoparasitic combinations on the host.10aAnimal Husbandry10aanimals10aBrazil10aDiptera10aectoparasite10alice10aLice Infestations/economics/epidemiology/veterinary10aQuestionnaires10aScrew Worm10aSeasons10asheep10aSheep Diseases/economics/epidemiology/parasitology10aTick Infestations/economics/epidemiology/veterinary10aticks1 aMadeira, N., G.1 aAmarante, A., F.1 aPadovani, Carlos, Roberto uhttp://www.phthiraptera.info/sites/phthiraptera.info/files/44992.pdf02990nas a2200169 4500008004100000245007100041210006900112260000900181300001400190490000700204520247900211100002202690700001402712700001702726700002002743856005702763 1992 eng d00aLouse and mite infestation in domestic animals in northern Nigeria0 aLouse and mite infestation in domestic animals in northern Niger c1992 a121 - 1240 v243 a

Records of domestic animals brought to the Veterinary Entomology Laboratory for diagnosis of suspected lice and mite infestation over a 10 year period were analysed. From a total of 794 suspected cases, 137 (17.3%) and 247 (31.1%) were positive for lice and mange mites respectively. The most common lice species recorded were Linognathus vituli (66.7%) on cattle, L. ovillus (83.3%) on sheep, Haematopinus suis (100%) on pigs and Menacanthus stramineus (54.5%) on poultry. Other lice species recorded included Haematopinus bovis and Solenopotes capillatus on cattle, Damalinia ovis on sheep, Linognathus stenopsis and Menacanthus stramineus on goats, Goniocotes sp. on a horse, Linognathus setosus and Menacanthus stramineus on dogs, Goniodes gigas, Lipeurus caponis, Menopon gallinae and Chelopistes meleagrides on poultry. The most common mite species were Demodex folliculorum on cattle (96.9%) and on dogs (80.8%), Sarcoptes scabiei on pigs (100%) and Notoedres cati (80.3%) on rabbits. Other mite species included Psoroptes communis, Cheyletiella parasitivorax, Ornithonyssus gallinae and Dermanyssus gallinae.

Resumen

Se analizaron los registros de animales domésticos llevados al Laboratorio de Entomologís Veterinaria, para diagnóstico de posible infestación con piojos y ácaros, durante un período de 10 años. De un total de 794 casos sospechosos, 137 (17·3%) y 247 (31·1%) fueron positivos para piojos y ácaros, respectivamente. Las especies más comunes de piojos encontradas fueronLinognathus vituli (66·7%) en ganado,L. ovillus (83·3%) en ovejas,Haematopinus suis (100%) en cerdos yMenacanthus stramineus (54·5%) en aves. Otras especies de piojos encontradas incluyeron,Haematopinus bovis ySolenopotes capillatus en ganado;Damalinia ovis en ovejas;Linognathus stenopsis yMenacanthus stramineus en cabras;Ganiocotes sp. en caballos;Linognathus setosus yMenacanthus stramineus en perros;Goniodes gigas, Lipeurus caponis, Menopon gallinae yChelopistes meleagrides en aves.

Las especies más comúnes de ácaros fueron,Demodex folliculorum en ganado (96·9%) y en perros (80·8%);Sarcoptes scabiei en cerdos (100%) yNotoedres cati (80·3%) en conejos. Otras especies detectadas incluyeron,Psoroptes comunis, Cheyletiella parasitivorax, Ornithonyssus gallinae yDermanyssus gallinae.
