| Popis: | Solid, controlled-release dispensers containing 2 g of the synthetic attractant trimedlure now are used in Jackson traps to detect the Mediterranean fruit fly, Ceratitis capitata (Wiedemann). Panel traps consisting of trimedlure mixed in a sticky substance and spread on the surfaces of a plastic panel are used to delineate the limits of discovered insect infestations in California. We describe the development of controlled-release, polymeric panels that prolong release of trimedlure and a highly attractive analog, ceralure. Attractants were incorporated in a polyethylene matrix to form panels and in a polymer coating on cardboard panels that then were evaluated by biological and chemical assay. In addition, commercial polymer matrix panels were evaluated. Field bioassay tests conducted in Hilo, HI, using released flies and in Guatemala in a natural population showed that the polyethylene matrix panel became brittle and cracked during field exposure and that release rates of the attractants were relatively low. The coated cardboard panels were stable under field conditions and yielded high fly captures for up to 6 wk. Farma Tech commercial panels containing 12.3 and 23.4 g of trimedlure remained highly attractive throughout a 134-d test in Hawaii and appear to be a long-lasting alternative to panels coated with trimedlure in Stikem. The cost of the relatively high dose of trimedlure is offset by the prolonged active life of the panel. Commercial panels from AgriSense (10 g trimedlure and 10 g ceralure) released the attractants at a slower rate and were less attractive. |
