Classical Biological Control of the Citrus Leafminer in Florida

The citrus leaf miner (CLM), Phyllocnistis citrella Stainton, a gracillariid moth, has established and spread rapidly throughout the citrus-growing areas of Florida. Ultimately, a variety of pest management tactics will have to be employed to manage the CLM, including cultural, chemical and biological controls. Relying solely on chemical control is expensive and unlikely to be feasible for very long because this pest can develop resistance to pesticides. Biological control by parasites already present in Florida may provide some control (J. Pena, UF-IFAS, Homestead and P. Stansly, UF-IFAS, Immokalee, personal communications). However, it seems unlikely that the generalist parasites already present in Florida will provide adequate control of the CLM.
