摘要： Cyantraniliprole is a novel anthranilic diamide insecticide with significant efficacy against Bemisia tabaci, an important pest insect worldwide. In this study, we conducted reversion and selection work and genetic analysis, and determined cross-resistance spectrum and synergism of cyantraniliprole resistance based on the reported population, SX population, of B. tabaci collected from Shanxi Province, China. Compared with a susceptible strain (MED-S), SX population, the field-evolved cyantraniliprole-resistant population exhibited 26.4-fold higher resistance to cyantraniliprole. In SX, a sharp decline of cyantraniliprole resistance was shown in the absence of selection. Another tested strain, SX-R, was established from SX population after successive selection with cyantraniliprole and recently developed 138.4-fold high resistance to cyantraniliprole. SX-R had no cross-resistance to abamectin, imidacloprid, thiamethoxam, sulfoxaflor, or bifenthrin. Genetic analysis illustrated that cyantraniliprole resistance in SX-R was autosomally inherited and incompletely dominant. Additionally, piperonyl butoxide (PBO) significantly inhibited cyantraniliprole resistance in the SX-R strain. In conclusion, the selection of SX with cyantraniliprole led to high resistance to cyantraniliprole which is incompletely dominant and no cross-resistance to several common types of insecticides. Enhanced oxidative metabolism is possibly involved in the resistance of SX-R, yet target-site resistance could not be excluded.
