Resumo: | The stomach contents of females from the genus Culicoides were studied to determine their blood food sources and the degree of relations established between these insects and their hosts. The specimens were captured by using CDC light traps within the period from March 2009 to February 2010, in two rural towns in the island of São Luís, Maranhão, Brazil. A total of 930 engorged females were captured, belonging to 12 Culicoides species. Precipitin reaction examination was used, which revealed the blood from 7 different vertebrate types that had been sucked, and the most frequent were: bird (41.9%), rodent (21.2%), dog (15.4%), and human being (7.3%). In double reactions there was a predominance of bird/dog (20%) and dog/cat, dog/opossum, bird/rodent, opossum/rodent, and cat/human being (13.3% each). Among the Culicoides species found, C. paucienfuscatus Barbosa, 1947 stood out, because it only sucked blood from birds. The 11 remaining species have sucked blood both from domestic and synanthropic animals, and 4 out of them also sucked human blood. The results allowed us to conclude that C. paucienfuscatus showed specific relations, it was considered as ornithophilous and the other species were generalist. The presence of these animals in a peridomestic environment is a factor that favors the maintenance of Culicoides in rural villages and the presence of human being among the most sucked vertebrates indicates that besides being included in the diet of female Culicoides, it may participate in occasional epidemiological cycles of parasites, due to the eclectic habit of these insects. |

O conteúdo estomacal de fêmeas do gênero Culicoides foi estudado para determinar suas fontes alimentares sanguíneas e o grau de relações estabelecidas entre esses insetos e seus hospedeiros. Os espécimes foram capturados em armadilhas luminosas tipo CDC no período entre março de 2009 e fevereiro de 2010, em duas localidades rurais da ilha de São Luís-MA. Foram capturadas 930 fêmeas ingurgitadas, pertencentes a 12 espécies de Culicoides. Foi utilizado o exame da reação da precipitina, que revelou o sangue de sete tipos diferentes de vertebrados que haviam sido sugados, sendo os mais frequentes: ave (41,9%), roedor (21,2%), cão (15,4%) e ser humano (7,3%). Nas reações duplas predominaram ave/cão (20%) e cão/gato, cão/gambá, ave/roedor, gambá/roedor e gato/humano (13,3% cada). Dentre as espécies de Culicoides encontradas, C. paucienfuscatus Barbosa, 1947 destacou-se, por ter sugado apenas sangue de aves. As 11 espécies restantes sugaram sangue tanto de animais domésticos como de sinantrópicos, sendo que, destas, quatro também sugaram o sangue humano. Os resultados permitiram concluir que C. paucienfuscatus apresentou relações específicas, foi considerada ornitófila e as outras espécies foram generalistas. A presença desses animais em ambiente peridoméstico é um fator que favorece a manutenção dos Culicoides nos povoados rurais e a presença do ser humano como um dos vertebrados mais sugados indica que além de fazer parte da dieta das fêmeas de Culicoides, pode participar de eventuais ciclos epidemiológicos de parasitas, devido ao hábito eclético desses insetos.Universidade Federal de Santa Catarina2014-12-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2015v28n1p5110.5007/2175-7925.2015v28n1p51Biotemas; v. 28 n. 1 (2015); 51-582175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2015v28n1p51/28661Copyright (c) 2015 Gaudino Marco Cantanhede Gusmão, Elias Seixas Lorosa, Gustavo Almeida Brito, Leandro Santos Moraes, Vagner de Jesus Carneiro Bastos, José Manuel Macário Rebêloinfo:eu-repo/semantics/openAccessGusmão, Gaudino Marco CantanhedeLorosa, Elias SeixasBrito, Gustavo AlmeidaMoraes, Leandro SantosBastos, Vagner de Jesus CarneiroRebêlo, José Manuel Macário2017-10-19T17:00:38Zoai:periodicos.ufsc.br:article/32591Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2017-10-19T17:00:38Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
