Molecular identification of resistance to organophosphates and carbamates in Aedes aegypti of different physiological ages in a cemetery in Peru.

ABSTRACT: In 2024, a cross-sectional, quantitative, and descriptive study was conducted to molecularly identify resistance to organophosphates and carbamates in Aedes aegypti of different physiological ages in a cemetery in northern Peru. Female specimens were captured, taxonomically identified, their ovaries dissected, and the parity percentage calculated. Likewise, the legs of nulliparous, parous, and gravid females were dissected, DNA was extracted, and PCR was performed to detect the mutant ACEr gene associated with resistance to organophosphates and carbamates. A total of 218 (100%) females were captured, with a nulliparity index of 37,61% and a parity index of 62,39%, of which 13,23% of parous females were gravid at the time of capture. The ACEr gene was detected in all three physiological age
