Resumo

The Atlantic Forest is one of the most important areas of biodiversity in the world, but it has been largely replaced with agropastoral areas and at the present only 12.5 % of the original cover remains. Despite the ecological importance of insects, few studies have been used in conservation approaches for the Atlantic Forest, mainly due to a great taxonomic impediment. A group quite ecologically important but deeply neglected includes parasitoid wasps that control a great number of invertebrates, like tiphiid wasps that are parasitoids of underground coleopteran larvae. The present study aimed to estimate Tiphiidae species richness and diversity in 15 patches of a highly fragmented Atlantic Forest region, using factors that drive the diversity pool from a metacommunity, such as immigration and speciation probabilities. The parameters were estimated using the Neutral Biodiversity Theory, which is based on the total ecological equivalence of species at the same trophic level. Diversity values were molded to the area size, the immigration probabilities, and/or the speciation probability. Eight genera and 460 individuals of Thynninae, Myzininae and Tiphiinae were collected. Variation in species richness, estimated by both rarefaction and first-order jackknife methods, was explained by patch size and by immigration and speciation probabilities. These variables also explained the variation in Shannon diversity and species evenness. Variations in species richness and diversity of Tiphiidae are strongly associated with neutral processes, but they are also influenced by forest fragmentation and intensive agricultural activities.
