Abstract

Composite polymer dispensers capable of controlled release of semiochemicals have been developed. The dispensers make use of a solid elastomer matrix reservoir which is at least partially surrounded by a permeable release rate controlling polymer membrane. The matrix materials are polyurethanes compatible with many types of semiochemicals and additives. The release rates of semiochemicals from the dispensers can be varied over a wide range by manipulation of the reservoir conditions and by selection of the type of permeable polymer membrane surrounding the device. The dispensers can have a variety of forms and can be produced by a simple process. The semiochemical devices produced by this method are useful for managing insect and other pests through attraction to traps, for population monitoring or for mass trapping. The devices may also be used to dispense anti-aggregation pheromones or repellents in addition to use for mating confusion or disruption.
