Get information on how to identify them (pictures), possible means by which you can treat, control and manage citrus leafminers. The egg first appears as a tiny dew drop, usually alongside the midvein on the underside of the unexpanded leaf. Among herbivore insect guilds, leaf miners support the most diverse parasitoid assemblages and the highest parasitism rates, providing successful cases of classical biological control (Hawkins, Reference Hawkins 1994, Karamaouna et al., Reference Karamaouna, Pascual-Ruiz, Aguilar-Fenollosa, Verdú, Urbaneja and Jacas 2010).

The adult is a small moth (wingspan approximately 5mm) which lays eggs on flushes of new growth. The adult female moth lays her eggs on young citrus leaves and when they hatch, the larvae immediately burrow under the surface of the leaf. The University of Florida's Institute of Food and Agricultural Sciences (UF/IFAS) is a federal-state-county partnership dedicated to developing knowledge in agriculture, human and natural resources, and the life sciences, and enhancing and sustaining the quality of human life by making that information accessible. Identify the problem. Thesystem works by emitting high quantities of sexual pheromones that disrupt mating and the males' ability to find females. Due to the biology of CLMs chemical control of the species is extremely difficult.
