目的 依据《卫生杀虫剂现场药效测定及评价灭蝇饵剂》（国家标准报批稿）在现场检测灭蝇毒饵灭蝇效果，评价检测方法的可行性及灭蝇饵剂的应用效果。方法 2015年9月，选择上海市奉贤区4类场所，设试验组A、B、C和对照组D，按照5 g/10 m²的用药量，利用相对密度下降率（R_d）评价灭蝇效果。结果 3个试验组4 h的R_d均>75%，24 h的R_d均>85%，R_d达到合格标准。3个试验组在最小范围内（30 cm）死蝇率为84.00%。结论 《卫生杀虫剂现场药效测定及评价灭蝇饵剂》可用于现场检测灭蝇毒饵的灭蝇效果，拜灭敌杀蝇饵剂现场灭蝇效果合格。

Objective According to the Standard Draft (Efficacy testing methods and assessment of public health insecticides-fly bait), to evaluate the field efficacy of one fly bait(Baimiedi) and verify the feasibility of the efficacy testing method. Methods Set 3 treatment groups(A, B and C) and one control group(D), compare and evaluate field efficacy of the testing bait using R_d(relative density decline rate) as the assessing criteria, according to the Standard Draft. Results After bait treatment, the R_d of 3 groups(A, B, and C) were greater than 75%(4 h) and 85%(24 h), the R_d met the standard's requirement. The flies mortality of 3 groups were 84.00% in the minimum range(30 cm). Conclusion The testing bait has an excellent field efficacy against flies, and the Standard Draft can be used as a testing method for field effect assessment of fly bait.
