none The survey carried out during the years 1979-1980, 1980-1981 and 1981-1982 indicate that among pupal parasites Opius turcicus (Fischer), Opius exiguus (Wesm.) (Braconidae) and Sphegigaster sp. (Pteromalidae) are major parasites of Chromatomyia horticola (Gour.) (Diptera: Agromyzidae) on Pisum sativum and Brassica campestris. The parasitism by the pupal parasites O. turcicus and O. exiguus, shows that in the beginning O. turcicus remains the dominant component till January. Thereafter, O. exiguus outnumbers the former and remains numerically superior till the crop is harvested. The pupal parasite Sphegigaster sp. plays relatively minor role in controlling the pest population.
