Release of Semiochemicals: Natural Polymers

Abstract

Semiochemicals are substances involved in chemical communication between individuals and can alter the behavior and physiology of individuals. The use of semiochemicals in pest control has grown and today it is an important tool in pest control and constitutes an interesting alternative to pesticides, reducing environmental risks, to farmers, consumers and pest resistance. This study addresses the types of semiochemical releasers currently used and the polymers in their compositions. This is a descriptive study, of the literature review type, with searches on the Capes journal portal, the SciELO, Elsevier, Web of Science and PubMed databases. Incorporating semiochemicals into controlled release devices is necessary to optimize their applicability as pest control agents, providing adequate release that meets the needs of the environment. Therefore, semiochemical releasers must meet some specifications, such as biodegradability and constant release kinetics. Biodegradable matrices are preferred for modified release, with starch, chitosan and sodium alginate being some of the materials of choice for this.
