The experiment was conducted in Randomized Block Design with three replication to evaluate the integrated management of rice yellow stem borer (Scirpophaga incertulas Walk.) in rice-wheat cropping system under low land condition. All the treatments had the comparable lowest number of dead hearts, white heads,number of productive tillers and filled grain than untreated control. Among tested treatments Fipronil@ 75 gm a. i./ha was found best, because it provide minimum dead hearts, white heads and maximum productive tillers, filled grain and yield,However, Fipronil treated plots have maximum numbers of predators than other insecticides treated plots. Maximum number of different predators was found in Trichogramma japonicum treated plot followed by tobacco and neem extract plots.
