The double-mutation（M918I + L1014F）kdr allele is fixed in Cimex hemipterus populations in Guangxi, China

Four putative knockdown resistance ( kdr ) mutations have been documented in the voltage-gated sodium channel ( VGSC ) gene of Cimex hemipterus from several countries. However, no information regarding kdr mutations in any Chinese tropical bed bug population is available to date. In this study, a double-mutation（M918I + L1014F） kdr allele was identified in six C. hemipterus populations across Guangxi Zhuang Autonomous Region of China. The...
