Resumen
Aedes aegypti, vector de enfermedades como el dengue, la fiebre amarilla, el zika y el chikungunya, ha sido combatido en Argentina principalmente con insecticidas químicos, los cuales generan resistencia y contaminación ambiental. Este estudio evaluó el efecto adulticida de siete terpenos y su sinergismo con el piperonil butóxido (PBO) sobre Ae. aegypti. Se realizaron bioensayos con diferentes dosis de terpenos y sus combinaciones con PBO. Los terpenos más tóxicos fueron la pulegona y el citronelal, con los menores valores de CL50. Se recomienda explorar el uso de la pulegona como base para insecticidas naturales contra Ae. aegypti.
Abstract Aedes aegypti, the vector of dengue, yellow fever, Zika, and chikungunya viruses, has been primarily controlled in Argentina using chemical insecticides, which cause resistance and environmental contamination. This study evaluated the adulticidal effect of seven terpenes and their synergistic effect with piperonyl butoxide (PBO) on Ae. aegypti. Bioassays were conducted with different doses of terpenes and their combinations with PBO. The most toxic terpenes were pulegone and citronellal, which had the lowest CL50 values. It is recommended to explore the use of pulegone as a base for natural insecticides against Ae. aegypti.
