Abstract
The present investigation was carried out under laboratory condition at Plant Protection Research Institute (Sharkia Branch) to evaluate, Protecto, Biovar, Biorinza, Jojoba oil, diflubenzuron and chlorpyrifos against Spodoptera littoralis.
Obtained results indicated that the mean duration period of the different larval instars of S. littoralis fed on castor bean oil leaves treated with different concentrations of Biovar, Biorinza, Protecto and jojoba oil. Cleared that all tested compounds caused markedly prolongation in the duration period of the larval instars compared to control. Generally, increasing the concentration caused increasing mortality percentage for the tested compounds. Also the tested compounds caused markedly prolongation in the duration period of the pupal stage. The lowest concentrations caused the highest percent deformation of pupae for the tested compounds. Biovar recorded highest reduction in percent of adult emergence. The higher concentration applied of the four compounds tested the higher percent of reduction in the eggs number per female. Chlorpyrifos was the most potent insecticide and diflubenzuron was the least toxic material to the cotton leafworm, the three applied concentrations of each tested compound decreased the total soluble protein in the 2nd instar larvae of S. littoralis as compared to control at the inspected times. The tested compounds increased the activity of GOT and GPT enzymes in the 2nd instar larvae as compared to control at different time intervals. And increased invertase activity after 2, 5 and 7 days of application.
