The pigeonpea pod borer, Helicoverpa (=Heliothis) armigera (Hbn.) in recent years has been identified as a pest which acquired resistance to many of the commonly used insecticides (Dhingra et al., 1988). The unabated population explosion of this pest since 1986 in Andhra Pradesh confirmed the understanding that even synthetic pyrethroids are quite ineffective against this pest. Studies made by Santharam et al. (1981), Jayaraj et al. (1989) and Sithanantham (1987) indicate that nuclear polyhedrois virus (NPV) can be used to contain this pest at field level. Hence, studies were conducted at the Regional Agricultural Research Station, Lam in collaboration with the Central Biological Control Station, Hyderabad on the utility of NPV against the pigeonpea pod borer.
