Continuous surveillance of malaria vectors’ resistance to public health insecticides is vital for effective malaria control interventions.

Insecticide resistance undermines the effectiveness of vector control measures, posing a significant challenge to malaria control efforts. Insufficient local data on insecticide resistance in Nigeria hampers malaria control strategies and may result in the procurement of ineffective tools. Insecticide-treated nets (ITNs) containing alpha-cypermethrin and piperonyl butoxide (PBO) can be effective for malaria control in areas with pyrethroid resistance. Malaria Consortium distributed ITNs containing alpha-cypermethrin and PBO during campaigns conducted in December 2021 and August 2022 in Ondo and Anambra states, respectively. Our study aimed to assess insecticide resistance status and genetic markers of target-site resistance in Anopheles gambiae s.l. populations.
