USE OF METAL CARBOXYLATE GLASSES IN THE CONTROLLED-RELEASE OF BIOACTIVE MOLECULES - CULEX-QUINQUEFASCIATUS OVIPOSITION PHEROMONE

Mixed metal carboxylate glasses have recently been developed, and it is shown that these are good hosts for Culex quinquefasciatus oviposition pheromone. The glasses degrade in a humid environment, releasing the volatile pheromone in a controlled fashion. Successful aerial release of the pheromone was demonstrated in an oviposition choice bioassay, showing both time and dose relationships. The glasses alone did not affect the behavioural responses of the mosquitoes.
