Popis:	Studies were conducted on the species composition of parasitoids of sorghum midge, Stenodiplosis sorghicola Coquillett (Diptera: Cecidomyiidae), emergence pattern and level of parasitism. They took place at the International Crops Research Institute for the Semi-Arid Tropics Asia Centre using three midge-resistant (ICSV 745, ICSV 89058 and IS 10712) and three susceptible (Swarna, CSH 9 and ICSV 112) genotypes during the 1992-93 post-rainy and 1993 rainy seasons. The species of parasitoids collected were Aprostocetus gala Walker, A. coimbatorensis Rohwer (Hymenoptera: Eulophidae) and Eupelmus spp. (Hymenoptera: Eupelmidae). The species composition varied with the season, but was unaffected by varietal resistance and susceptibility to the midge. Although both species of Aprostocetus were present in rainy and post-rainy seasons, A. gala was predominant during the rainy season whereas A. coimbatorensis was predominant in the post-rainy season. There was no significant difference in the pattern of parasitoid e...
