上海市奉贤地区动物饲养场应用艾科净生物制剂灭蝇效果研究

Effects of Echo against flies in the animal farms of Fengxian district,Shanghai

目的研究探索新型生物制剂的现场灭蝇效果。方法在同一饲养场内采用艾科净、灭幼脲、吡丙醚的单剂和艾科净+灭幼脲复配剂以及空白作对照,用同一稀释倍数对模拟现场和现场畜粪堆进行喷洒处理。结果模拟现场艾科净处理同一批不同暴露阶段畜粪堆(产生后24、48和72h)12d后家蝇的羽化率分别下降96.2%、64.4%和86.7%;现场以艾科净、艾科净+灭幼脲复配剂处理后7、12d蝇幼虫密度平均分别下降56.2%、65.5%;与空白对照比较,现场以艾科净处理畜粪12d后成蝇密度下降71.2%,以艾科净+灭幼脲复配剂处理畜粪12d后成蝇密度下降55.2%;现场应用艾科净喷洒招蝇场所,6h后蝇密度下降74.5%。结论模拟现场和现场试验研究证明,新型生物剂艾科净具有较好的除臭、抑制蝇类孳生和降低成蝇密度的作用。

Objective To explore the on-site fly control effects of a new biological agent,Echo,in animal farms. Methods Echo,chlorbenzuron,pyriproxyfen,a mixture of Echo with chlorbenzuron,and a blank control were sprayed at the same concentration onto feces in a laboratory simulation and in the field. Results After treatment with Echo for 12 days,compared to the control group,the emergence rate of flies from the feces exposed at 24 h,48 h and 72 h,decreased by 96.2%,64.4% and 86.7%,respectively. After treatment with Echo and the mixture of Echo and chlorbenzuron for 7 days and 12 days in the field,the density of fly larvae decreased by 56.2% and 65.5%,respectively. After treatment with Echo for 12 days,fly density decreased by 71.2% compared to the control. After treatment with the Echo and chlorbenzuron mixture for 12 days,fly density decreased by 55.2% compared to the control. Fly density also decreased by 74.5% after treatment with Echo for 6 h in the field. Conclusion The results show that Echo was effective in deodorization,inhibition of fly breeding and reduction of fly density.
