          Abstract

          Este estudo foi conduzido para verificar a ocorrência de forídeos parasitóides da saúva Atta laevigata (Smith) na região de Porto Nacional, TO, e para avaliar algumas características biológicas dessas moscas. Para tanto, entre outubro/2002 e setembro/2003, em intervalos de aproximadamente 15 dias, foram realizadas 22 coletas, cada uma contendo em média 149,5 ± 82,9 operárias, totalizando 3.704 formigas. No laboratório, as formigas eram distribuídas em grupos de cinco indivíduos por placa de Petri e mantidas a 25 ± 1ºC e 80 ± 5% UR, sendo alimentadas diariamente, até sua morte, com solução de mel a 50%. Foram coletadas 106 operárias (2,8%), com ou sem carga (fragmento vegetal), parasitadas por forídeos: 72 operárias (68%) estavam parasitadas por Apocephalus vicosae Disney; 28 (26,4%) por Neodohrniphora erthali Brown; e seis (5,6%) por Apocephalus attophilus Borgmeier. As maiores taxas de parasitismo por A. vicosae (3,9-5,4%) foram registradas nos meses secos de junho a agosto, enquanto que o parasitismo por N. erthali manteve-se abaixo de 2,3% ao longo do ano. As operárias maiores estavam parasitadas pela espécie de maior tamanho N. erthali ou pela espécie que produz o maior número de larvas A. attophilus. O registro das três espécies de forídeos no Cerrado do Tocantins amplia a distribuição desses parasitóides no Brasil. Ao mesmo tempo, o desenvolvimento da larva de A. vicosae no tórax do hospedeiro e a ruptura entre o pronoto e a propleura da formiga para a emergência desta mosca são características inéditas do parasitismo de saúvas por forídeos.

          The purpose of this study was to verify the occurrence of parasitism in Atta laevigata (Smith) by phorids in Porto Nacional, Tocantins, Brazil and to evaluate some biological characteristics of those flies. From October/2002 to September/2003, at 15-day intervals, 22 samplings were carried out (149.5 ± 82.9 workers each) comprising 3,704 ants. In the laboratory, the ants were distributed in groups of five individuals per petri dish and maintained at temperature of 25 ± 1ºC and 80 ± 5% of RH. They were fed daily with a 50% honey solution until death. The total of 106 workers (2.8%), collected with or without load (plant fragment), were parasitized by phorids: 72 workers (68%) were parasitized by Apocephalus vicosae Disney, 28 individuals (26.4%) by Neodohrniphora erthali Brown, and six (5.6%) by Apocephalus attophilus Borgmeier. The higher parasitism rates by A. vicosae (3.9-5.4%) were observed during the dry season (June-August), while the parasitism by N. erthali was lower than 2.3% throughout the year. The bigger workers were parasitized by bigger parasitoid N. erthali or by parasitoid with larger number of larvae A. attophilus. The occurrence of three phorid species in Tocantins broadens the distribution of these flies in Brazil. The development of A. vicosae larva within the thorax of the host as well as the rupture between the ant pronotum and propleuron so that the emergence of the fly can take place are characteristics not yet described on parasitism of leaf-cutting ants by phorids.
