Abstract

                                The susceptibility of 19 varieties and nine hybrids of sorghum to shoot fly. Atheri- gona varia soccate (Rond.) was studied. Among the varieties N.J. 1953 recorded the minimum of 1.4 per cent and 302 recorded the maximum of 8.4 per cent under protected conditions, and N J. 1953 registered the lowest incidence of 9.9 per cent under unprotected conditions. In case of hybrids SPH 4 showed the maximum of 34.7 per cent damage under unprotected conditions. The yield loss due to shoot fly damage was also found to be significant.
