2011 Annual Report
Field trials were conducted to document the longevity of pheromone-mediated mating disruption of citrus leafminer (CLM) following applications of SPLAT-CLM™ to citrus groves at locations in Florida. SPLAT (Specialized Pheromone & Lure Application Technology) is an emulsified wax slow-release delivery matrix designed to provide prolonged release of volatile compounds in the field. Single applications of 200 g/acre of SPLAT-CLM (0.15 percent A.I.) provided approximately six weeks of effective disruption of trap catch. Design improvements to a tractor-mounted computer-controled applicator led to the fabrication of an advanced prototype capable of treating more than300 acres/day. We have progressed significantly towards our goal of providing the citrus industry with the first use of insect semiochemicals as a control measure for a major pest in commercial citrus and a means of mechanical application to large areas. Continued effort will focus on extending the longevity of individual applications of SPLAT-CLM and reducing costs.
Progress was monitored through direct involvement in field activities, meetings with collaborators, telephone calls and email communication.
