Resumo: This work is part of a wider project than it seeks to make risings, revise, describe, publish the taxonomy and help on the systematic, with publication of the illustrations of species morphology of parasitoids species acurring the Rio Grande do Sul. The data of the parasitoids associated were related with Brassolis astyra Godart, 1824 and Opsiphanes invirae amplificatus Stichel (1904) bionomy, from observations and capture in four places of the state of Rio Grande do Sul: São Martinho da Serra (SMS), Tupanciretã (TP), Santa Maria (SM) and Camobi-Berleze (BE). The parameters analyzed to Brassolis astyra were: postures biometry, pupae longevity average, adults' average emergency rates, adult s body wight and volume, pupae and wings morfometrics from anatomic landmarks. Eggs collected in Tupanciretã (TP), urban area, hatched 46%, and were parasited 43% and 11% failure. However, eggs of the São Martinho da Serra (SMS), natural area, 4% hatched, 95% were parasited and 1% failure. With base in the adults emergency from pupae 77% of males and females presented a normal morphology (viable) and 23% were malformed. Xanthozona melanopyga was registered (Wiedmann, 1830) (Diptera: Tachinidae) as parasite of Brassolis astyra pupae. In Opsiphanes invirae amplificatus the parasitoids observed were: Conura maculata (Fabricius, 1787) and Cotesia alius (Muesebeck, 1958) (Hymenoptera: Braconidae: Microgastrinae). Conura maculata, pupae parasitoid, is the first record to the Rio Grande do Sul. Are presented too data about the emergency time, the adults' longevity and sexual rate. It is presented, also, an ilustrated description of the main external morphologic characteristics of the species. Cotesia alius, caterpillar parasitoid, is the first record for Rio Grande do Sul state, also. The study present data about the cocoons and average cocoons number, by posture, and the emergency time elapsed, the adults' longevity and sexual rate. Four Eulophidae family species were observed hyperparasiting C. alius cocoons: Horismenus opsiphanis Schrottky, 1909 and Horismenus sp. (Entedoninae), a new specie according to Dr. Christer Hansson (Lund University, Sweden); and the Oomyzus Sokolowskii Kurdjumov, 1912 and Aprostocetus sp., (Tetrastichinae), new specie also, according to Dr. John La Salle (Commonwealth Scientific Industrial and Research Organisation, Australia), can be considered a new specie too. Diagnoses of all parasitoids are presented, including the new species.
