ABSTRACT
This study was conducted in a caged-layer installation located on Echaporã, state of São Paulo, Brazil. The objective was to survey parasitoids of immature Musca domestica, Stomoxys calcitrans and Muscina stabulans (Diptera: Muscidae). Fly pupae were collected biweekly from manure, from May, 1988, to May, 1989. Most of them were hidden in manure portions where moisture rates ranged from 45 to 63%. The following species were recorded: Spalangia cameroni, Spalangia endius, Spalangia gemina, Pachycrepoideus vindemmiae (Pteromalidae), Eurytoma sp. (Eurytomidae) and Tachinaephagus zealandicus (Encyrtidae). Spalangia drosophilae and Spalangia nigroaenea were only found parasitizing S. calcitrans. T. zealandicus was responsible for the highest degree of parasitism and it was thus considered the main parasitoid species observed.
