Citrus leafminer, Phyllocnistis citrella Stainton (Gracillariidae: Lepidoptera), is a major and potential pest of citrus fruits which causes extensive damage to young leaf flush by making shallow tunnels. Its young larvae after emergence from eggs feed in tunnels and later on curling of leaves occur. This study evaluated the efficiency of two bio-control agents i.e. Chrysoperla carnea (5, 10 and 15 larvae per plant along with control) and Trichogramma chilonis (1, 2 and 3 egg cards along with control and each card contained 200 eggs) on population infestation of citrus leafminer during the spring sprouting season in 2014. Experiment was conducted according to randomized complete block design with three replications. Population infestation of citrus leafminer was recorded 24 h pre- and 24, 48 and 72 h post-treatment of Chrysoperla carnea larvae and at 24 h pre- and 3, 6 and 9 days post-treatment of Trichogramma chilonis egg cards. Results reflected that Chrysoperla carnea and Trichogramma chilonis significantly reduced the population infestation of citrus leafminer by 14 and 17%, respectively
