RESUMO
A survey was conducted to verifY the rei ative and sazonal aboodance of Musca domestica L. 1758 and its parasitoids, in microhabitats of a dairy cattle farm. The experiment was conducted for one year, collecting weeldy samples, ftom march/1994 until february/1995, at the farm ofSão Paulo University, in Pirassununga, SP. Puparium ofM. domestica and other synanthropic dipterous were coll~ in certain places oftwo microhabitats. In the laboratory, these puparium were placed in gela tine capsules waiting for the adult emergence and, after 40 days, the puparium which presented no emergence, were dissected to analyse the causes of death. These causes were quantified and statistically analised. The following species of Diptera were collected: Musca domestica L., Stomoxys calcitrans (L.), Physiphora aenea (Fabr.) and Sarcophagula sp. Associated to them, the parasitoids collected were: Aleochara puberula (K1ug), Aleochara bipustulata (L.) (Coleoptera: Staphylinidae: Aleocharinae); Spalangia cameroni Perkins, Spalangia endius Walker, Spalangia nigroaenea Curtis, Spalangia gemina Boucek, and two especies of Muscidifurax ( Hymenoptera: Pteromalidae). The species A. puberula, S. comeroni and S. endius were the most important species parasitizing M. domestica, althougb they have showed different sazonality. The population of M. domestica was influenced by temperature and precipitation, but parasitoid species were influenced by the flies density, showing the possibility that could be a density-dependence relationship
