Relationship between deltamethrin resistance and midgut symbiotic bacteria of Aedes albopictus by 16S rDNA sequencing

The diversity of bacteria colonizing the intestines of resistant larvae was richer than that of sensitive larvae, while the inverse is correct for adults. This suggests that the intestinal commensal bacteria of Ae. albopictus adults and larvae may play different roles in their deltamethrin resistance. This study provides an empirical basis for further investigation of the mechanisms of gut microbes in insecticide resistance and new prospects for mosquito control.
