MiR-279-3p-mimic-injected DR-strain mosquitoes are more sensitive to deltamethrin. a Relative expression of miR-279-3p was 2.72-fold higher in the DR-strain mosquitoes at 72 h after injection with the miR-279-3p mimic, compared to the NC and control groups. b Relative expression of CYP325BB1 was decreased by 61.3% in the DR-strain mosquitoes at 72 h after injection with the miR-279-3p mimic compared to the NC and control groups. c Mortality following 7 mg/l deltamethrin treatment of the miR-279-3p-mimic-injected group ranged from 57.4 to 74.5% at 90–120 min in the CDC bottle bioassay, which was higher than that in the acetone control, control and NC groups. Data are representative of three technical replicates of three biological replicates and are reported as the mean ± SEM. Asterisks indicate significant difference at *P < 0.05, **P < 0.01, ***P < 0.001. Abbreviations: RE Relative expression
