Abstract

Ten plant extracts and two commercial botanicals were evaluated for their ovipositional repellent property against Plutella xylostella under laboratory conditions. Among the plant products tested, Azadirachta indica at 0.5 per cent concentration recorded maximum reduction in egg laying both under no choice (50.33%) and free choice (62.43%) conditions at 24 h. Whereas, least repellency was noticed with castor, Ricinus communis extract.
