Abstract
The objective of this study was to appraise the occurrence of parasitoids of the family Chalcididae in Itumbiara County, State of Goiás, central Brazil. Insect samples were collected in pastures and native forest areas using pan traps, from January to December 1998. The traps consisted of circular yellow plastic containers (30 cm in diameter and 12 cm in height) containing a mixture of 2 L of water, 2 ml of detergent, and 2 ml of formaldehyde. Samplings were performed weekly by placing 10 traps at soil level (5 traps in the pasture and 5 in the woods). During 1998, 121 specimens of Chalcididae were collected. Haltichella sp.4 was the most abundant species collected (15.7%).

Melanosmicra is retricted to the Neotropics where there are about 30 species (Hanson & Gauld, 1995)
The genus Dirhinus consists of about 15 species in the Neotropics region which are parasitoids in puparia of various Diptera (Calliphoridae, Muscidae, Sarcophagidae, and Tephritidae)
Summary
Parasitóides da família Chalcididae coletados em pastagens e mata utilizando-se armadilhas de bacias amarelas, em Itumbiara, Goiás, Brasil. O objetivo do presente estudo foi relatar a primeira ocorrência de parasitóides da família Chalcididae em Itumbiara, GO. O material estudado foi coletado em áreas de pastagem e de mata nativa, usandose bacias amarelas contendo água, no período de janeiro a dezembro de 1998. All Chalcididae are parasitoids of larvae or pupae of other insects, mostly Lepidoptera and Diptera, and Coleoptera, Neuroptera, and Hymenoptera (Clausen, 1940; Burks, 1960; Grissell & Schauff, 1990).
