  ABSTRACT: The effect of foliar spray of young lemon trees with Chitosan (CH) (200 - 300 - 400 ppm), on antioxidant enzymes activities (peroxidase POD, polyphenol oxidase PPO) and total phenolic content, and their influence on leaf miner (Phyllocnistis citrella) activity (tunnel length and damage density) under field condition was investigated. The results showed that treatment with chitosan 300 ppm enhanced the total phenolic content (5.975 mg/g) and the POD activity (0.533 min-1 mg-1 protein), while PPO activity was increased by chitosan 200 ppm (1.394 ΔA/min/g FW). The results demonstrated as well that chitosan treatment has a beneficial effect in reducing leaf miner activity, by decreasing tunnel length and damage density.
