Impact of dual active ingredients long-lasting insecticidal nets on the genetic structure of insecticide resistant populations of Anopheles gambiae in Southern Benin.

ABSTRACT:

Background

Insecticide resistance amongst vector populations is a major challenge, exacerbated by the continued use of the same active ingredients. The present study assessed the impact of long-lasting insecticidal nets (LLINs) bi-treated with chlorfenapyr-alphacypermethrin (PY-CFP LLIN) or pyriproxyfen-alphacypermethrin (PY-PPF LLIN) on the genetic structure of resistant populations of Anopheles gambiae in 60 clusters divided into three arms from three districts in southern Benin.

Methods

The study was conducted between September 2019 and October 2021 in 123 villages grouped in 60 clusters. Mosquitoes were collected indoors and outdoors using human landing catches (HLCs) in 4 households in each cluster every 3 months. After morphological identification, a subsample of An. g
