ALTERNATIVE AND LOW-COST DISTILLER FOR ESSENTIAL OILS TO OBTAIN A NATURAL REPELLENT IN THE FIGHT AGAINST ARBOVIRUSES

Abstract

The Aedes aegypti mosquito is the central vector of transmission of dengue, zika and chikungunya. In Brazil, the socio-environmental conditions favor the expansion of the mosquito, allowing a better adaptation. Research shows that alternative methods to chemical control have presented good results in controlling mosquitoes, such as the use of essential oils (EOs) from plant species such as citronella leaf essential oil. As a result, the present study aimed to carry out a homemade system for extracting essential oils from citronella leaves and to develop a natural repellent based on alcohol, glycerin and citronella oil, so that the school community can use it on a daily basis. The essential oil extraction system was developed with recyclable and low-cost materials. The method proved to be efficient in the extraction of essential oil, since the yield was compatible with that observed in the literature. In addition, the use of this tool enabled new scientific knowledge and ensured the organization of a more interactive and innovative learning process.
