IMPROVED CONTROLLED-RELEASE FORMULATIONS FOR A NEW TRAP DESIGN FOR MALE MEDITERRANEAN FRUIT-FLIES - THE C-AND-C TRAP

The Mediterranean fruit fly, Ceratitis capitata, is a major pest of fr uits and vegetables in the world. With the help of an extensive trappi ng program, the continental United States has remained free of establi shed medfly populations. In an effort to increase trapping efficiency, controlled-release polymeric panels with trimedlure and ceralure were developed in conjunction with the development of a new trap, the C&C trap. This study contrasts the effectiveness of different panel formul ations with the standard trimedlure polymeric plug and describes the u se of the panels in the C&C trap. Field tests in Hawaii using released sterile flies showed consistently higher male medfly catches with pan els in C&C traps than with the standard trimedlure polymeric plug in J ackson traps.
