Evaluación del falso pimiento (Schinus Molle), como posible insecticida en el control biológico de larvas del mosquito Aedes aegypti, en condiciones de laboratorio

Abstract

Dengue is a viral disease transmitted mainly by female mosquitoes of the Aedes aegypti species and, in lesser cases, of the Aedes albopictus species. These mosquitoes, known as vectors of transmission, have been the focus of multiple efforts to minimize cases of severe Dengue in the country, causing at least 41,365 confirmed cases of a Dengue serotype. Most of the current efforts against the Dengue vector are focused on eradicating the vector by means of fumigation with chemical agents such as insecticides or larvicides. Although these chemical means have an effect as vector eradicators, they also have associated environmental problems, mainly because the chemical agent does not discriminate between the vector and other organisms present in the environment. Therefore, and based on previous studies, the objective of this research and innovation project was to establish whether the oily extract of the false bell pepper (Schinus molle) has properties as a toxic agent in the larval activity of the A. aegypti mosquito. The results of this research indicate that the oily extract of False Pepper has an inhibitory effect on larval activity, since, in the bioassays, a mortality higher than 90% was obtained at a concentration of 1500 ppm, after 48 hours.
