Parasitoids of dipterans and hemipterans collected in to cultivate on maize in Brazil

Abstract

This paper has the objective of relating the occurrence of parasitoids to cultivate on maize in Itumbiara, Goiás during the crop 2001. Four groups of parasitoids were collected: two Brasema sp. (Hyemnoptera: Eupelmidae), two of Conura sp. (Hymenoptera: Chalcididae), eleven Gryon gallardoi (Bréthes, 1913) (Hymenoptera: Scelionidae) and nine of Pteromalidae sp. (Hymenoptera: Pteromalidae). The most important obtained parasitoids were found in Leptoglossus zonatus (Dallas, 1852) (Hemiptera: Coreidae) with Brasema sp. and G. gallardoi, prevailing the parasitism of 26,8% and 4,8%, respectively. Hymenoptera is one of the largest orders of insects. The lesser known Hymenoptera are parasitoids that develop in immature stages of other arthropods. They are considered important in the biological control of insect pests.
