Identification of Knockdown Resistance Mutations in the Cimex hemipterus (Hemiptera: Cimicidae) in Iran.

ABSTRACT: The worldwide resurgence of tropical bed bug Cimex hemipterus beginning in the late 1990s has led to growing concern. Molecular data on pyrethroid resistance, which is essential for the control strategies, is unknown for C. hemipterus in Iran. The current study evaluated the deltamethrin resistance status of C. hemipterus by bioassay and molecular tests. Live bed bugs were collected from sleeping quarters (dormitories) in the city of Tehran and used for insecticide bioassay tests. For bioassay evaluation, mixed-sex pools of adult bugs were exposed to deltamethrin (0.025%)-treated paper. Polymerase chain reaction assay evaluated resistance-related mutations in the voltage-gated sodium channel gene (VGSC) gene of studied populations. On the basis of the bioassay test within the 48-h exposure
