Insecticidal activities among the three dsRNAs (dsATPase A, dsATPase B, and dsTLR6) specific to vATPase-A, vATPase-B, and TLR6, respectively, against F. occidentalis. A Comparative analysis of the dsRNAs by feeding a dose of 500 ppm to both larvae and adults. A viral gene CpBV302 was used as the control dsRNA. Mortality was assessed at 7 days after treatment (DAT) and corrected by the mortality of control treatment obtained by feeding the control dsRNA. B Dose-mortality curves of the two dsRNAs against the larvae and adults. Test insecticide suspensions were applied to the thrips by the feeding method. Each treatment used 10 individuals and was replicated three times. The letters above the standard deviation bars indicate significant differences among the means at Type I error = 0.05 (LSD test). C Median lethal time (LT50) of the two dsRNAs against larvae and adults
