- Abstract
The most common control method, and practically the only intentionally targeted to kill this insect, is the use of chemicals, which can exceed a number of 15 applications per season. This increases production costs, affects human's health, causes environmental pollution, resistance to insecticides and elimination of natural enemies, among other problems. It is suspected that this plague is becoming resistant in some production areas; therefore, bioassays were made with pepper weevil populations from La Cruz de Elota, Culiacán and El Rosario, Sinaloa to determine the susceptibility of the pest to insecticides chlorpyrifos-ethyl, malathion, oxamyl, Z-cypermethrin and Thiamethoxam which are used for its combat. These results suggest that the population of La Cruz de Elota has developed slight tolerance to chlorpyrifos ethyl, malathion and oxamyl insecticides, because the resistance ratio values obtained were greater than 10x, compared with a susceptible population of El Rosario. For thiamethoxam, the results indicate that the same population has developed high levels of tolerance, with a resistance ratio of 50.4x.
