In order to evaluate the larvicidal and biochemical effects of some aromatic plant oils against the cotton leafworm larvae, Spodoptera littoralis (Boisduval), the present investigation was carried out. Four commercial aromatic oils; garlic, mint, eucalyptus, and lavender oils, were tested against 2nd and 4th instar larvae. Results showed that all tested oils were so efficient, especially; the garlic oil as it exhibited the least LC50 value for both 2nd and 4th instar larvae. Results also revealed significant disruption (either reduced or enhanced) enzyme activity. In conclusion, tested oils proved to have insecticidal, antifeedant, and inhibitory enzymatic activity effects. So that, tested oils can be applied safely in IPM program for the cotton leafworm, Spodoptera littoralis control.
