[Objective] The paper aimed to screen out efficient and safe insecticides against Cerataphis lataniae Biosduval. [Method] Control effects of five insecticides against C. lataniae were studied through indoor bioassay and field trial. [Result] Bioassay results showed that the indoor toxicities of 10% α-cypermethrin,22% sulfoxaflor and 10% imidacloprid were higher,with LC 50 of 15.28,30.00 and 30.23 mg/L,respectively. In field trials,the control effects of 10% α-cypermethrin,22% sulfoxaflor and 10% imidacloprid against C. lataniae were over 90% for all the concentrations at 10 d post adminstration. The control effect of 22% sulfoxaflor reached 100% for all the concentrations at 5 d post administration. [Conclusion]10% α-cypermethrin was a superior pesticide against C. lataniae,but 22% sulfoxaflor and 10% imidacloprid were more efficient in emergency.
