Abstract
Acetone extractives of various parts of eight indigenous plants viz. leaves of Tagetus (Compositeae), Ipomoea (Convolvulaceae), Acacia (Mimosaceae), Lawsonia (Lythraceae), Eucalyptus (Myrtaceae), seeds and flowers of Lantana (Verbenaceae), flowers of Bignonia (Bignoniaceae) and fruits of Cassia (Caesalpiniaceae) were tested for their oviposition deterrent properties against the rice moth. Leaf extracts of Tagetus, Ipomoea and Acacia exhibited nearly 50% reduction in oviposition, while remaining six treatments were less effective.
