Several attempts have been made to control the gram pod borer Heliothis armigera (Hbn.) on different crops with the nuclear polyhedrosis virus (NPV) in India (Jayaraj and Rabindra, 1989). On sunflower, two applications of NPV at 250 LE/ha could effectively control H. armigera (Rabindra et al., 1986). Recently, the NPV of H. armigera was formulated into wettable powders and dusts and found effective against H. armigera larvae in the laboratory (Ethiraju et al., 1988). This communication deals with a pot culture study on the efficacy of NPV formulations against H. armigera larvae on sunflower heads.
