Abstract: Thiamethoxam, indoxacarb, and chlorantraniliprole were evaluated against Aedes aegypti populations from northeast Mexico resistant to permethrin and deltamethrin due to kdr mutations (C1534F, V1016I, V410L). Bottle bioassays revealed LC50 values ranging from 0.24 to 0.97 µg/bottle and LC95 values from 3.25 to 17.53 µg/bottle. Resistance ratios (RR) for all three insecticides were below 10, indicating susceptibility. These results suggest their potential for integration into insecticide rotation programs for improved Aedes aegypti control.
