Abstract

The chloroform extracts of Callistemon lanceolatus and Vinca rosea alone and their different mixtures (viz., 1:1, 1:3 and 3:1) were tested on feeding against third instar larvae of Helicoverpa armigera Hub. by leaf dip method under laboratory conditions. The results revealed that, out of these two plants tested highest antifeedant activity was observed after 24 hr in chloroform extract of V. rosea (5270 ppm) followed by C. lanceolatus (5605 ppm). Among the various mixtures tested 3:1 ratio of both the plants (C. lanceolatus and V. rosea, AI50= 1216 ppm) showed highest antifeedant activity followed by 1:1 (3044 ppm) and 1:3 (5354 ppm).
