New occurrence of Gryon gallardoi (Brèthes, 1914) (Hymenoptera, Scelionidae) Hemiptera parasitoid in Brazil

The objective of this study was to investigate the occurrence of Gryon gallardoi (Brèthes, 1914) (Hymenoptera, Scelionidae) in the municipality of Itumbiara, Goias Brazil. The collections were weekly, with 10 traps, placed at ground level and randomly distributed, in a total of five basins in the pastures and five in the forest. These traps consisted of spherical yellow plastic basins, approximately 30 cm in diameter and 12 cm high where a mixture of 2 liters of water, 2 ml of detergent and 2 ml of formaldehyde were deposited. During 1998, 1013 specimens of Scelionidae were collected, and 109 specimens of G. gallardoi were identified, constituting 10.7% of the Scelionidae. A total of 480 samples were collected and 63 specimens were collected from pastures (57.8%) and 46 from the forest (42.2%).The results found in this work allow to extend the geographic distribution of G. gallardoi in Brazil.
