Sorghum midge, Contarinia sorghicola Coq. (Cecidomyiidae: Diptera), is the most important pest of grain sorghum worldwide. The effect of midge-resistant cultivars on economic injury levels (EILs) for sorghum midge was studied on two midge-resistant (ICSV 197 and ICSV 745) and four commercial cultivars (CSH 1, CSH 5, ICSV 1 and ICSV 112). There was a linear relationship between midge density and percentage loss of grain in the midge-susceptible cultivars CSH 1, CSH 5, and ICSV 112. However, there was only a marginal increase in midge damage with an increase in midge density in the midge-resistant cultivars ICSV 197 and ICSV 745 while ICSV 1 showed a moderate increase in midge damage [...].
