The sensitivity of Spodoptera littoralis 2 nd and 4 th instar larvae towards the essential oils (mint and lavender oils) and aqueous plant extracts (Artemisia herba-alba and Catharanthus roseus) were investigated under laboratory conditions and the effect of sublethal concentrations on the feeding deterrence were evaluated on the insect. Results revealed that 2 nd and 4 th instar larvae of S. littoralis were more susceptible to lavender oil than mintoil as it has higher LC50 values. In addition, the results showed that the mean feeding deterrence (FDI%) of essential oils and botanicals extracts was concentration-dependent. Therefore, these botanicals could be important as eco-friendly accessible pest control alternatives against S. littoralis and other closely related species.
