摘要

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