Figure 6. Knockdown in the expression of ClCPR reduced the resistance to deltamethrin.

Figure 6

(A) The percent survival of dsRNA treated CIN-1 (deltamethrin resistant population without para-type sodium channel gene mutation at 419 aa and 925 aa) bed bugs at 0.06 µg deltamethrin 5 days after dsRNA injection. The mortality was recorded after 24 h exposure to deltamethrin (3 replicates, 50–60 individuals for each replicate). (B) The % survival of dsRNA treated NY-1 (deltamethrin resistant population with 2 para-type sodium channel gene mutations at 419 aa and 925 aa) bed bugs at 0.06 µg deltamethrin 5 days after dsRNA injection. The mortality was recorded after 24 h exposure to deltamethrin (3 replicates, 38–40 individuals for each replicate). (C) The % survival of dsRNA treated LA-1 (deltamethrin susceptible population without para-type sodium channel gene mutation at 419 aa and 925 aa) bed bugs at 0.0006 µg deltamethrin 5 days after dsRNA injection. The mortality was recorded after 24 h exposure to deltamethrin (3 replicates, 60 individuals for each replicate). The differences between control and CPR-KD in three bed bug populations were analyzed by Student's t-test.
