title: Sampling methods for assessing social wasps species diversity in a eucalyptus plantation.
abstract: Social wasps were collected in a eucalyptus (Eucalyptus urograndis, a genetically enhanced eucalyptus) plantation in Juiz de Fora, state of Minas Gerais, southwestern of Brazil, by using a variety of sampling methods, including active capture and baited traps set at two microhabitats. Six new records of social wasps for this region were obtained during the study: Brachygastra lecheguana Latreille, Polybia ignobilis Haliday, Polybia occidentalis Olivier, Polybia platycephala (Richards), Protonectarina sylveirae Saussure, and Protopolybia exigua Saussure (Hymenoptera: Vespidae). The active capture method sampled the greatest number of species. Baited traps installed in the canopy sampled agreater number of individuals of social wasps than those set on the trunks of eucalyptus trees. Fruit based baits captured a greater number of social wasp species than those baited with a protein derivative. Once no method was able to sample all species, we concluded that the efficiency of a survey can be maximized by using traps with a variety of different baits, in combination with active capture methods.
