| Abstract | ||||
| The objective of this study was conducted to determine the efficacy of three plant extracts; (Achook 0.15 % (Azadirchtin)), Cloves oil(Syzygium aromaticum) and Plant extract damasesa (Ambrosiamaritima) ,using different rates of concentrations on the fourth instar S. littoralis larvae mortality, the contents of carbohydrates, proteins and lipids and some enzymes activity. Obtained data showed that cloves oil exhibited the highest reduction percentages and toxic action followed by neem extract, while damasesa extract was the lowest one. The larval duration was significantly affected by all treatments, as well as the total carbohydrates, proteins and lipidssuffered considerable reduction of the treated 4th instar larvae of S. littoralis whereas, they were highly significant with cloves oil and Azadirchtin extract non-significant with damasesa extract, except total lipids were significant with both neem and damasesa extract. The Trehalase, Amylase and Invertase enzymes were significant affected by different treatments. | ||||
