Abstract

Many insecticides and repellents synthetics commercially available and considered by the population as the only effective way to control insects, are usually toxic, non-specific and pollutants, causing damage to the health of humans and to the ecosystem. The spread of dengue across the country is also a consequence of the non-selectivity of chemical insecticides and the resistance presented by the Aedes aegypti to these insecticides. There are many organic bioactive compounds produced by plants, potential for mosquito control, but they are inefficient when applied freely due to evaporation or leaching of active molecules, which results in reduced duration of insecticide / larvicide effect. Despite widespread public concern about environmental and health effects by the use of synthetic pesticides, natural pesticides must topple as commercially viable alternatives for reduced risk products. To overcome the instability of natural products, microencapsulation techniques have been used in different areas. Microencapsulation protects sensitive materials that can suffer degradation, enables the application in defined doses without direct contact with the active compound and can promote the controlled and gradual release of the active component. The objective of this project is to produce biodegradable carriers for controlled release of natural larvicides in a domestic environment. The prioritized technique aims to further industrial production of these carriers for allowing natural products be transformed into viable alternatives using low cost materials and with no risk of toxicity to the consumer and the environment. The development of these carriers is seen as a auxiliar measure for controlling the growth of larvae of Aedes aegypti, the vector of dengue, chickungunha and Zika virus. (AU)
