【摘要】：目的评价50%杀螺胺乙醇胺盐悬浮剂的实验室和现场杀螺效果。方法在实验室和现场采用50%杀螺胺乙醇胺盐悬浮剂浸杀、喷洒法灭螺,并与50%氯硝柳胺乙醇胺盐可湿性粉剂进行效果比较。结果室内浸杀,50%杀螺胺乙醇胺盐悬浮剂24、48 h和72 h LC_(50)值分别为0.092 6、0.062 9 mg/L和0.054 9 mg/L;室内0.25 mg/L浸杀24、48 h和72h,钉螺死亡率均为100%;室内喷洒,0.25 g/m~2 3 d后钉螺死亡率即可达100%。江陵现场,除0.5 g/m~3浸杀24 h钉螺死亡率为96.67%外,其余浓度组钉螺死亡率均为100%。公安现场,0.5 g/m~3及以上浓度组浸杀钉螺2 d后,钉螺死亡率可达100%;江陵现场,0.5 g/m~2喷洒1、3 d和7 d后钉螺死亡率分别为87.5%、92.82%和97.40%。公安现场,0.5 g/m~2喷洒1、3 d和7 d后钉螺死亡率分别为85.94%、86.78%和94.21%,且1.0 g/m~2组钉螺死亡率均高于实验对照组WPN。结论 50%杀螺胺乙醇胺盐悬浮剂具有较好的实验室和现场杀螺效果,为新型高效、使用方便的灭螺药物剂型。
[Abstract]:Objective to evaluate the efficacy of 50% spiramine ethanolamine suspension in laboratory and field. Methods 50% ethanolamine salt suspension was used in laboratory and field to kill molluscicides, and the results were compared with those of 50% niclosamide ethanolamine salt wettable powder. Results the values of 50% ethanolamine suspension were 0.092 and 0.054 9 mg / L for 48 h and 72 h, respectively, and the mortality of snail was 100 mg / L for 24 h and 72 h for 0. 25 mg/L and 0. 25 g/m~2 / 3 d respectively, and the mortality rate of snail was 100 mg / L after indoor spraying of 0. 25 g/m~2 for 3 days. In Jiangling field, the mortality rate of snails was 96.67% except 0.5 g/m~3 for 24 h, and the mortality rate of other concentration groups was 100%. The mortality of Oncomelania hupensis in 0.5 g/m~3 and above concentration groups could reach 100 and 87.5% 92.82% and 97.40% respectively after spraying 0.5 g/m~2 for 3 days and 7 days at Jiangling site. The mortality rate of snails sprayed with 0.5 g/m~2 was 86.78% and 94.21% respectively, and the mortality rate of 1.0 g/m~2 group was higher than that of the experimental control group. Conclusion 50% spiroamine ethanolamine suspension has good efficacy in laboratory and field. It is a new effective and convenient dosage form for snail killing.
