A study of the arthropod fauna from bovine dung pats in the State of Goiás, Brazil, was carried out from January to December, 1998. Twenty samples of bovine dung were taken at random, each month, from eight day old pats, placed in plastic containers and taken to the laboratory. The arthropods were extracted by flotation in water in order to determine the frequency of Coleoptera, Diptera, Hymenoptera and Macrochelidae (Acarina) considered important in the degradation of cattle dung, and in the control of dung flies. Fifty two arthropod species belonging to 10 families were collected: 20 of Coleoptera (three families), 12 of Diptera (three families), 10 of Hymenoptera (three families) and six of Macrochelidae (Acarina).

The objective of this paper was to report on the occurrence of parasitoids of Tuta absoluta Meyrick (Lepidoptera: Gelechiidae) on tomato plants, under greenhouse conditions, in Lavras County . The rate of parasitism for the three species was 4.2%, 0.2%, and 2.6%, respectively. This is the first reported occurrence of Earinus sp. parasitizing Tuta absoluta in Brazil.
