Botanicals act not only as insecticides but also function as antifeedants, oviposition deterrents and ovicides. The present investigation reports on the antifeedant property of leaf components of (07) seven plant extracts (Azima tetracantha, Chloroxylon sweietenia, Clerodendrum viscosum, Cleistanthus collinus, Lippia javanica, Ocimum americanum and Sphearanthus indicus) against (04) four test insects (Hyblea purea Tinolius eburneigutta, Eutectona machearalis, and Atteva fabricella) at different concentrations was done. All insect cultures were maintained in a growth chamber in the laboratory at a temperature of 27 2 C, 12 12 LD and with 70 5 % RH during the experiments and the antifeedant activity observed in all the plant extracts based on the feeding behavior of the test insect and arranged in the descending order is 1.0 %greater than0.8 %greater than0.6 %greater than0.4 %greater than0.2 %greater than0.1 % concentrations and uncontrol. At 1.0 per cent concentration found to be the most effective and potent antifeedant against these leaf feeding insect pest.
