Author(s): Manish Kumar, Rekha Israni and Rakesh Gupta
Abstract: The feeding deterrence of three commercial Insect Growth Regulators; Diflubenzuron, Precocene II and Rakshak were evaluated at 1.0, 0.5, 0.25, 0.125, 0.06, 0.03, 0.015 and 0.007 per cent concentrations for larvae of the lemon butterfly, Papilio demoleus in the laboratory. Results showed that the Diflubenzuron, Precocene II and Rakshak treated larvae showed maximum antifeedant activity of 84.92, 83.60 and 83.38 at 1% concentration respectively .The antifeedant activity were increased with increasing concentration. All three Insect Growth Regulators exhibited significant antifeedant effect, and Papilio demoleus larvae on treated leaves quickly stopped feeding and dropped off treated leaves, resulting in no or minimal damage on the treated lemon leaves.
