试验现场灭蝇毒饵效果评价及检测方法验证

Efficacy evaluation of the fly bait and feasibility verification of the testing method

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/10m^2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4h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 Rd （relative density decline rate） as the assessing criteria, according to the Standard Draft. Results After bait treatment, the Ra of 3 groups （A, B, and C） were greater than 75%（4 h） and 85% （24 h）, the Ra 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.
