Evaluación Del Efecto Larvicida De La Borra Café En Larvas De Aedes Aegypti En Condiciones De Campo Y Laboratorio

Abstract

The larvicidal effect of coffee grounds in Aedes aegypti stage 4 was evaluated in laboratory and field conditions as a pilot test. 7 treatments were used in the laboratory from 3 gr / L to 9 gr / L, the most effective concentration was determined to perform field tests, with treatment 7 (9 gr / L) being the concentration with 99% effectiveness. In the field, 5 hatcheries were used to apply the bioassay in several larval stages in order to determine the average lethal time, for which in all bioassays larvicidal effectiveness was achieved in more than 50% of the specimens.
