摘　　要：[ Objective] The paper aimed to explore the dose-reduced pesticide control technique of Bradysia odoriphaga Yang et Zhang. [ Method] The field trids were carried out by routine spraying method, and the control effects of mixtures of Beichuang （ Liangfenbao and Jianweikang） and less dose of phoxim than conrentional against B. odoriphaga larvae were examined. [Result] The results indicated that the control effects of mixtures （containing 14% of Liandeibao or Jian- veikang and 30% -40% less phoxim than conventional dosage） against B. odoriphaga larvae were 84.01% -2.46% and 81.07% -86.12%, respectively. The mntrol effects were equivalent to the conventional dose of phoxim （89.42%）. [ Conclusion] When Beichuang is mixed with phoxim in controlling B. odor/phaga arvae, the suitable reduction level of phoxim is 30% -40%.[ Objective] The paper aimed to explore the dose-reduced pesticide control technique of Bradysia odoriphaga Yang et Zhang.
