A field experiment was carried out at Rajasthan college of Agriculture, MPUAT, Udaipur during the two consecutive years 2015-16 and 2016-17 in a randomized block design with seven treatments and three replications. Sugarcane variety COH 119 was planted for experiment purpose. Treatments of Acephate 50% + Imidacloprid 1.8% SP, Acephate 75% SP and Imidacloprid 17.5% SL were drenched in open furrow after planting whereas, phorate 10% G was broadcasted in open furrow at planting. The two-consecutive years of experimentation has shown that applications of Acephate 50% + Imidacloprid 1.8% SP @ 3000 and 2500 g per ha found to be most effective treatment to manage sugarcane insect pest complex (Termite, white grub, early shoot borer and pyrilla) and simultaneously significant higher yield was recorded. It was also found that Acephate 50% + Imidacloprid 1.8% SP did not significantly reduce the prevailing natural enemies' populations in sugarcane ecosystem as well as found non-phytotoxic to the sugarcane crop at recommended dose.
