A Case of Gynandromorphism in <I>Amblyomma oblongoguttatum</I> (Acari: Ixodidae)

Abstract: During a survey conducted from August to November 1998 to ticks associated with dogs in the rural area of Uruará, in the state of Para, Eastern Amazon region of Brazil, we collected one gynandromorph specimen out of 18 Amblyomma oblongoguttatum Koch specimens collected from dogs. It is a perfect bipartite gynandromorph, reported in this species for the first time.

“…Ginandromorfos são indivíduos quiméricos constituídos por tecidos geneticamente masculinos e femininos, os quais expressam fenótipos sexuais condizentes com seu sexo genético, levando ao desenvolvimento de um indivíduo com partes de ambos os sexos (LABRUNA et al, 2002). O ginandromorfismo ocorre na natureza em diversas espécies de vertebrados e invertebrados, incluindo os carrapatos (LABRUNA et al, 2000). O exemplar ginandromorfo de A. dubitatum, apresentou na vista dorsal características masculinas do lado esquerdo e femininas do lado direito, sendo o inverso na vista ventral (Figura 1 A-C).…”

“…Dois casos de ginandromorfismo de R. sanguineus s. l. já foram relatados no Brasil (PEREIRA & CASTRO 1945;LABRUNA et al, 2002). Fonseca, 1935e Labruna et al (2002, também publicaram dois casos em A. sculptum (publicados como A. cajennense) e Labruna et al (2000) um caso em Amblyomma oblongoguttatum no território nacional. Desta forma o presente estudo registra pela primeira vez um ginandromorfo de A. dubitatum, ampliando assim os relatos de carrapatos ginandromorfos no território brasileiro.…”
