First occurrence of Euneura sopolis (Hymenoptera, Pteromalidae) hyperparasiting Xenostigmus bifasciatus (Hymenoptera, Braconidae) in Brazil: implications for biological control of pine aphids

It is estimated that the planting of pinus in Brazil exceeds 2 million hectares comprising mainly two species Pinus taeda and P. elliottii. Due to the expansion of this culture and the often inappropriate cultural methods, this crop became increasingly susceptible to pest insects (Zaleski et al., 2005). Among these the aphids are outstanding due to their characteristics such as high fertility, presence of both wingless and winged forms, thus facilitating dispersal, parthenogenetic reproduction that coupled to the favorable Brazilian climatic conditions make them one of the most important pests of Pinus spp. plantations (Penteado et al., 2004).(AU)

Perfil da fauna de vespas parasitóides (insecta, hymenoptera) em uma área de mata atlântica do parque estadual de pedra azul, domingos martins, espírito santo, brasil

ABSTRACT A survey was conducted of the parasitic wasps from Parque Estadual de Pedra Azul in Espírito Santo State, Brazil. A total of 1,997 specimens of parasitoid wasps belonging to 28 families were collected with 16 Malaise traps exposed for 14 days. Diapriidae, Platygastridae and Bethylidae presented the highest relative abundance (26.54%, 11.47% and 10.72%, respectively). Fourteen families presented relative abundance lower than 1%. The subfamily Charipinae (Figitidae) was recorded for the first time in Espírito Santo State. A list of genera and species is presented.

RESUMO Este trabalho teve como objetivo conhecer a fauna de vespas parasitóides ocorrentes em área de Mata Atlântica no Parque Estadual de Pedra Azul, Espírito Santo, Brasil. Foram coletadas 1.997 vespas parasitóides pertencentes a 28 famílias através de 16 armadilhas Malaise expostas por 14 dias. As famílias Diapriidae, Platygastridae e Bethylidae apresentaram as maiores abundâncias relativas (26,54%, 11,47% e 10,72%, respectivamente). Quatorze famílias apresentaram abundância relativa inferior a 1%. A subfamília Charipinae (Figitidae) é registrada pela primeira vez para o Estado do Espírito Santo. É apresentada lista de gêneros e espécies de algumas famílias
