The Aedes aegypti mosquito serves as a vector for several diseases, including dengue, Zika, chikungunya, and yellow fever. This species is well adapted to urban environments poses significant threat public health. Some studies suggest that the gut bacteria of insect vectors may play crucial role in developing resistance insecticides. study assessed Ae. from Florencia, Caquetá, temephos deltamethrin analyzed diversity resistant larvae adult females. Larvae exhibited at lethal concentration 50 (LC50) 0.034 µg/mL, while females showed discriminant 10 µg/mL. bacterial load guts deltamethrin-treated (3.42 × 106 CFU/mL) was significantly higher compared temephos-treated (9.4 105 untreated (8 104 CFU/mL). A total sixty-eight strains were isolated both larval aegypti, with 31 identified through 16S rRNA gene analysis 11 confirmed by gyrB sequencing. In females, Bacillus comprised 12.55% an exclusive genus. larvae, Serratia most abundant genus, accounting 35.29%, Cedecea predominant representing 66.67%. These findings influence deltamethrin. Furthermore, this research provides valuable information can be considered design local control strategies. results highlight new focused on insecticide tolerance degradation within microbiota arboviruses.
