New agricultural techniques are attempting to reduce the application of synthesized pesticides and replace them with new environmentally friendly methods such as mass trapping, mating disruption, or chemosterilization techniques. All these methods are based on the release of a lure for insect attraction or confusion. The success of the chosen method depends on the quality of the attractant emission from the dispenser. Currently, used dispensers with a polymeric matrix and new dispensers with mesoporous inorganic materials were evaluated to obtain more efficient emission kinetics. In this study, the selected pest was the Mediterranean fruit fly, Ceratitis capitata (Wiedemann) and the lure used was trimedlure (TML). The dispensers were validated by means of a field study comparing insect catches with attractant release values. As a result, we have demonstrated that mesoporous dispensers have a clearly longer lifetime than the polymeric plug. Furthermore, the attractant release rate is less dependent on temperature in mesoporous than in polymeric dispensers.
