Mechanisms of pyrethroid resistance in Culicidae mosquitoes from Hainan Island, China.

ABSTRACT:

Background

Mosquito-borne diseases represent critical global public health threats. Insecticide-based prevention and interventions remain essential for disease and vector management. However, insecticide resistance in mosquitoes threatens the effectiveness of these management measures. This study investigated the susceptibility to pyrethroid insecticides and associated resistance mechanisms in five dominant mosquito populations on Hainan Island, China.

Methods

World Health Organization (WHO) tube bioassays were conducted to evaluate insecticide resistance profiles in Aedes albopictus, Culex quinquefasciatus, Armigeres subalbatus, Aedes aegypti, and Culex tritaeniorhynchus. We assessed the synergistic effects of pre-exposure to 4% piperonyl butoxide (PBO) on deltamethrin mort
