摘　　要：[目的]指导季节性栽培双孢蘑菇菇蚊菇蝇的科学防治,保障农产品质量安全。[方法]采用室内培养与田间试验的方法,对除虫脲开展室内生物活性试验与田间药效试验。[结果]室内生测试验表明对菌蛆的致死中浓度LC_(50)值为19.0193 mg/L。田间药效试验结果表明,在菇蚊菇蝇发生严重的情况下,对菇蚊菇蝇的防效在70.3%~97.2%之间。[结论]从持效期和农药使用准则考虑,在生产中可选用25%除虫脲WP 0.8~1.2 g a.i./m^2,于菇蚊菇蝇幼虫盛发期喷雾防治。[Aims] The study aims to guide the scientific control of mushroom and to guarantee the quality and safety of agro-products. [Methods] Indoor and outdoor experiment were conducted to evaluate efficacy of diflubenzttron. [Results] The results showed that the lethal concentration of 50 percent individuals （LC50） of difiubenzuron was 19.0193 mg/L. The field efficacy of diflubenzuron 25% WP indicated 70.3-97.2%. [Conclusions] Considering the pesticide persistence and guideline for application of pesticide, we recommend to use diflubenzuron 25% WP 0.8-1.2 gai/m^2 during the mosquito and fly in the young larvae peak period in the actual production.
