Composição faunística de vespas (Hymenoptera: Apocrita) do Parque Nacional da Serra da Bodoquena

Abstract

This work aims at performing the inventory of predator and parasitic wasps’ fauna in different forest formations of Bodoquena Range Mountain National Park (PNSB). The collections were made in the municipalities of Bodoquena, Bonito, Jardim and Porto Murtinho, covering the two parts (North and South) of PNSB, within a discontinuous period of 35 days of collecting, between february/2007 to december/2008. Seven expeditions were undertaken in the field, seven days each, in areas with predominance of deciduous and semideciduous seasonal forest. The data collection techniques employed in faunal inventory were active collection with entomological net, Malaise traps, yellow pads and mini-Winkler extractors. Three-hundred fifty one specimens Aculeata group, represented by 105 species in 57 genera, distributed in the following families: Vespidae, Pompilidae, Mutillidae; Tiphiidae; Scoliidae. The total number of individuals of the Hymenoptera Parasitica series’ in Bodoquena Mountain Range was 1243, following the percentage: Ichneumonoidea: Ichneumonidae (16%); Braconidae (9%); Platygastroidea: Scelionidae (18%), Platygastridae (1%); Proctotrupoidea: Diapriidae (11%), Chrysidoidea: Bethylidae (14%), Dryinidae (2%), Chrysididae (1%); Ceraphronoidea: Ceraphronidae (4%), Megaspilidae (1%); Evanioidea: Evaniidae (2%); Trigonalioidea: Trigonalidae (1%); and the superfamilies Chalcidoidea (19%) and Cynipoidea (1%). It was not possible to identify the families yet, for these two superfamilies, and all families of Parasitica were not possible to identify at the genera level. Some groups were sampled by one of the techniques employed, showing that the use of various techniques is essential to surveying wasps. The results of this study contribute to the knowledge of the richness of the wasps’ fauna and their geographical distribution and provide subsidies for insects’ fauna conservation in these forests.
