Sorghum as sole crop recorded higher shoot fly and stem borer incidence than sorghum intcrcropped with poplar tree. Among the two poplar tree systems, shoot fly incidence was found less in 15 × 2.5 m spacing than 10 × 2.5 m spacing but the reverse was true for stem borer. Within poplar systems the differences were not significant. HC 260 variety recorded higher number of egg and deadhearts due to shoot fly, and dead hearts, leaf injury and stem tunneling due to stem borer as compared to HC 171.
