Worldwide, there are many reports of pyrethroid resistance in bed bugs (Cimex spp.). Previous studies on the Common bed bug, Cimex lectularius L., have identified two mutations (V419L and L925I) in the voltage-gated sodium channel (VGSC) gene responsible for knockdown resistance (kdr). However, noth...
