| Abstract | ||
| Half lethal doses (LCsol of crude ethanohc extracts of Vinca rosea and Melia azedaracfl leaves (80 and SOppm. respectively) induced significant biochemical alterations in the second instar Larvae ( L2) of the fruit fly Ceratitis cap < /em>itata under Laboratory conditions. Activities of all enzymes tested (trehalase. amylase. invertase, lactic and isocitric dehydrogenases, alanine and aspartate transaminases) were significantly increased as a result of inclusion of both extracts in the Larval diet, while total protein, lipids, glucose, and glycogen contents were significantly decreased at the same doses. In the meantime, the free amino acid (FAA) content in the treated Larvae showed mild significant increase at these doses compared to the untreated control Larvae. Therefore, the macromolecular abnormalities observed in the second instar Larvae of C. ceputete can reflect the possible use of the two extracts as natural insecticides with special promising safe control of thrs insect. | ||
