Abstract

Helicoverpa armigera Hubner, chickpea pod borer is a serious pest of legumes, cotton and vegetables in the Indian subcontinent. Widespread appearance of resistance to chemical insecticides has stimulated efforts to develop alternative control methods including the use of insect viruses against this pest. Several workers proved the effectiveness of HNPV under field conditions in controlling H. armigera in chickpea (Dhamdhere and Khaire, 1986, Jayaraj et al., 1987, Cowgill and Bhagawat, 1996). However, there were several gaps in the utilization of HNPV and its affects on the life stages of H. armigera. This paper discusses the quantification of various ill effects of HNPV on Helicoverpa life stages under laboratory and the effect of Robin Blue as ultraviolet protectant with NPV in enhancing its persistence in chickpea ecosystem
