Field experiments were conducted at Experimental Field of Entomology, Department of Life Sciences, Manipur University for two consecutive crop seasons (2001 & 2002) to study the comparative performance of three biopesticides viz. Achook (2 ml/lit.), Neemall (5 ml/lit.) and B.I. (2 gm/lit.) with two insecticides viz. Cypermethrin (0.02%) and Dimethoate (0.05%) against pod borer complex of pigeonpea. The treatment with Achook showed better impact in terms of lower population density (4.29 & 16.81, respectively) in both the years. It also revealed the highest reduction percentage of 89.86 and 68.87 which was at par with Dimethoate in the first year and with Cypermethrin in the second year respectively but differed significantly from the rest of the treatllentS.
