Resumo
A comparative study of Braconidae (Hymenoptera) was conducted in two reserves in the Atlantic Forest, the Reserva Biológica Augusto Ruschi (RBAR) and Reserva Biológica de Duas Bocas (RBDB). Sampling was performed along a full annual cycle, using Malaise and Moericke traps. A total of 17 subfamilies were investigated, representing 3421 specimens and 403 species. Abundance, richness, diversity, faunistic similarity and, to a lesser degree, seasonality, were comparatively investigated between reserves and types of vegetation (i.e., Primary vs. Secondary forests). Abundance structure was similar between Reserves and between types of vegetation. Species richness was highest for RBAR (321 vs. 287 for RBDB), but the diversity in RBDB was highest if considering both traps pooled together. Faunistic similarity between the reserves was only 39%, with 40-46% of exclusive species in each of them. At nearly all levels of analysis, MP and MS were dissimilar, with MP showing higher values. Most species were collected during spring, but there was significant changes in species composition through the seasons. The results suggest that the observed structure of Braconidae biodiversity may represent a more generalized phenomenon in fragments of Atlantic forest.
