Field evaluation of Helicoverpa armigera nucleopolyhedrovirus formulations for control of the chickpea pod-borer, H. armigera (Hubn.), on chickpea (Cicer arietinum var. Shoba) in southern India
HearNPV was the slowest-acting of the three control agents, with average survival times (AST) of 5.5 days, compared with 3.2 and 4.3 days for larvae fed leaves treated with B. thuringiensis and endosulfan, respectively. Expand
Efficacy of nuclear polyhedrosis virus against Helicoverpa armigera (Hbn.) on Helicoverpa-resistant and susceptible varieties of chickpea
Hbn larval mortality due to nuclear polyhedrosis virus (NPV) was significantly higher on Helicoverpa -susceptible varieties (Shoba and Annigeri) than on the resistant accessions (ICC 506 and ICC 10817). Expand
Cannibalism on Nuclear Polyhedrosis Virus Infected Larvae By Heliothis Armigera (Hubn.) and its Effect on Viral Infection
Study on cannibalism by Heliothis armigera (Hubn.) larvae on nuclear polyhidrosis virus (NPV)-infected larvae and feeding on virosed cadavers revealed that cannibalism was significantly higher on NPV-infected (3 days post inoculation) larvae than either healthy larvae or those which had been just inoculated.

Influence of incubation temperature on productivity and quality of Spodoptera litura nucleopolyhedrovirus
The results indicate that maintenance of the SpltNPV production facility at 25 °C would enhance both the virus productivity and quality. Expand
Efficacy of biopesticides and natural plant products for Heliothis/Helicoverpa control
This chapter reviews the efficacy of biological pesticides, fungi, bacteria, protozoa and nematodes, and plant extracts against H. armigera; mass production of HaNPVs; and genetic modification of Ha NPVs for increased efficacy. Expand
Vacuum packaging of Corcyra cephalonica (Stainton) eggs to enhance shelf life for parasitization by the egg parasitoid Trichogramma chilonis
A novel and simple technique for storage of eggs of C. cephalonica by vacuum packing at 500 Hg−1 and stored at 8 ± 1 °C in refrigerator was developed to enhance egg viability for production of Trichogramma species, and assessed and compared with the traditional method. Expand
