Management of Bihar hairy caterpillar, Spilosoma obliqua (Walker) with a nuclear polyhedrosis virus

Field studies in groundnuts in Ludhiana, Punjab, India, showed that nuclear polyhedrosis virus at 250 LE/ha was effective against Spilosoma obliqua, but a period of at least 5 days was required to obtain sufficient mortality.
