Constraints on developing an integrated pest management program for citrus leafminer (Lepidoptera: Gracillariidae) in Florida nurseries
HortTechnology 8 (3), 332-345
Abstract: Florida citrus nursery growers were surveyed to learn about their citrus leafminer (Phyllocnistis citrella Stainton) (CLM) management practices as a preliminary step in developing an integrated pest management (IPM) program. All responses were kept anonymous. Survey responses from growers producing ~ 4.2 million trees annually were obtained, which represents most of the estimated 5.2 million trees required to annually replant Florida groves. Large nurseries (20%) each produced < 100,000 trees per year and jointly provided 88% of the trees produced annually. Small nurseries (80%) each produced <100,000 trees per year. The citrus leafminer was ranked the most important pest in nurseries during 1995. Pesticides used for CLM control included avermectin, azadirachtin, imidacloprid, fenoxycarb, diflubenzuron, and sulfur, in order of importance. Oil and soap also were used. Growers were concerned about the possibility that the CLM will develop resistance to pesticides. Producers potentially were willing to monitor CLM populations, switch pesticide types to improve survival of parasitoids of the CLM, and leave untreated trees inside the nursery to serve as refuges for CLM parasitoids. In order of importance, pest management advice was provided by private chemical companies, the Florida Citrus Pest Management Guide produced by the University of Florida/Institute of Food and Agricultural Sciences (UF/IFAS), UF/IFAS personnel, grower magazines, private consultants, the Florida Citrus Nurserymen's Association, and other growers.
