Helicoverpa armigera npv production manual

armigera. The total and differential haemocyte counts (THC and DHC) in H. armigera haemolymph were affected by nucIeopolyhedrovirus (NPV) treatment. There was a general decrease in THC in response to NPV treatment in both young and old larvae. However the decrease was more apparent in 5 and 8 day old larvae than in 10 day old larvae. Nuclear Polyhedrosis Virus (NPV) is host specific for Spodoptera litura and Helicoverpa armigera. NPV is a stomach poison. NPV is effective when it is ingested by the larvae. The mass production of NPV of H. armigera and S. litura is same except H. armigera is reared in individual vial to avoid cannibalism. NPV based management for Helicoverpa armigera in chickpea. In: National symposium on management of biotic and abiotic stresses in pulse crops, organised by Indian Institute of Pulses Research (Indian Council of Agricultural Research), held at Kanpur - (UP), India from June 26thth,

Helicoverpa armigera (Hübner) larvae were collected from field crops and wild hosts in India, Nepal and Pakistan from to , and ninety eight laboratory cultures established. armigera and H. punctigera, the major insect pests in our cotton/grain farming systems. NPV can be used in a variety of field crops, including sorghum, chickpea, cotton and maize. In sorghum, NPV is the preferred product for helicoverpa management, not only because it is.
