Abstract | ||
The volatile oils of dill, red basil, clove and peppermint were evaluated for their use as biologically active substances against the susceptible strains of the cotton leaf worm S. littoralis. Generally, all the tested volatile oils were efficient against the treated 4th instar larvae after 3, 5, 7 and 9 days post treatment. Red basil was the most effective volatile oil upon the treated larvae. They have been found to have some effects upon certain bio-physiological characteristics. Where their delayed effect on the survived 4th instar larvae post treatment was reflected on the rates of pupation, adult emergence, number of deposited eggs/female, and hatching percentage. | ||
