Análise faunística das subfamílias de Ichneumonidae (Hymenoptera) em um fragmento de Floresta Amazônica brasileira

Abstract

Ichneumonidae is one of the largest families of Hymenoptera, with an estimated 60,000 species, out of these 17,000 occurrences in the Neotropical Region. Despite its diversity, the group's studies are scarce in the Amazon region. Thus, the aim of this work was to carry out a faunal analysis of the subfamilies of Ichneumonidae in an area of the Amazon Forest and to present considerations about some genera. Two Malaise traps were installed in a forest area of Campus II of the Federal University of Amazonas - UFAM, in Itacoatiara, Amazonas. Weekly collections were carried out during the period from 2017 to January 2018. The Hymenoptera sampled were identified at the family and subfamily level, and subsequently referred to a specialist at the gender level. Faunistic Analysis was used to determine the main subfamilies. In all, 541 specimens of Ichneumonidae were chosen, distributed in 16 subfamilies. As subfamilies Cryptinae, Orthocentrinae, Ichneumoninae and Pimplinae predominate. It is worth mentioning the presence of Cremastinae Indicators and Campopleginae, which are important for the balance of natural populations, as well as being from degraded areas.
