32-O-05-Zeolites in sexual confusion: slow release of pheromones

This chapter presents zeolites in sexual confusion. Semiochemicals can be adsorbed in zeolites, and their diffusion–desorption rate can be controlled by modifying the physicochemical and structural parameters of zeolites. By matching the nature of the semiochemical, its functional groups, and the framework, extraframework composition, and pore topology of the zeolite, it is possible to design dispensers that help achieve the adequate air concentration of the pheromone (the most important group of semiochemical) within times long enough to be used for insect sexual confusion for the preservation of crops.
