Resumo(s)
Os Culicóides são insectos geralmente de proporções minúsculas de 1 a 2 M/m, pertencentes à família Ceratopogonidae que se encontram em quase todo o mundo exceptuando-se possivelmente, segundo Edwards, Oldroyd e Smart, a Patagónia e Nova Zelândia. As fêmeas são sugadoras de sangue picando segundo parece quase exclusivamente mamíferos e aves para o que possuem peças bucais suficientemente desenvolvidas, ao contrário dos machos que se alimentam de sucos de plantas. Algumas espécies picam mosquitos com o fim de obterem sangue directamente do estômago daqueles insectos. Assim a espécie Culicoides anophelis Edws. pica sobretudo anófeles aos quais pode ficar fixada durante longo período (até 48 horas) e ser transportado por eles durante o voo.
Culicoides are insects generally of tiny proportions of 1 to 2 M/m, belonging to the Ceratopogonidae family and found almost everywhere in the world, with the possible exception, according to Edwards, Oldroyd and Smart, of Patagonia and New Zealand. The females are bloodsuckers, biting, it seems, almost exclusively mammals and birds, for which they have sufficiently developed mouthparts, unlike the males who feed on plant juices. Some species bite mosquitoes in order to obtain blood directly from their stomachs. The species Culicoides anophelis Edws. bites mainly anopheles, to which it can remain attached for a long time (up to 48 hours) and be transported by them in flight.
