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 To test the effect of fly-killing bait for fly-killing in the field according to “Determination and evaluation of pesticide on-site efficacy and flies-baiting” (draft for approval of national standard), and to evaluate the feasibility of the detection method and the application effect of flies bait. Methods In September 2015, four sites in Fengxian District of Shanghai were selected. Groups A, B and C of the experimental group and control group D were set up. The relative density decreasing rate (R_d) was used to evaluate the flies in accordance with the dosage of 5 g / 10 m ~ 2 effect. Results The R_d of all the three experimental groups were> 75% at 4h, and the R_d values were> 85% at 24 h. The R_d reached the acceptable standard. The mortality of the three test groups was 84.00% within the minimum range (30 cm). Conclusion “Sanitation insecticide pesticide field efficacy determination and evaluation flies bait” can be used to detect fly-killing baits in the field.
