abstract
Studies on population dynamics revealed that the incidence of girdle beetle O. brevis and Green semilooper, Gessonia gema was high whereas moderate incidence of S. litura and A. modicella, was observed also the incidence of B. tabaci was very low / negligible. The incidence of girdle beetle studied in 31^st MW (1.19%) and riched to peak in 40^th MW (54.22%). The incidence of green semilooper, G. gema was observed throughout the crop season with peak of 25.33 larvae/mrl during 34^th MW.
