Abstract: Objective To compare the effectiveness of snail control between immersion of molluscicides through tide diversion and mollusciciding by spraying in marshland areas. Methods Immersion of 26% suspension concentrate of metaldehyde and niclosamide through tide diversion and spraying 26% suspension concentrate of metaldehyde and niclosamide alone were employed for snail control in two neighboring snail?breeding marshlands, and snails were surveyed before and after mollusciciding. The mortality of snails and the density of living snails were estimated. Results The density of living snails reduced by 72.19% and 100.00% 1 and 2 years after immersion of 26% suspension concentrate of metaldehyde and niclosamide through tide diversion, and 5.93% and 18.15% 1 and 2 years after spraying 26% suspension concentrate of metaldehyde and niclosamide alone. Conclusion Immersion of 26% suspension concentrate of metaldehyde and niclosamide through tide diversion is significantly superior to spraying 26% suspension concentrate of metaldehyde and niclosamide along for snail control, and implementation of immersion of 26% suspension concentrate of metaldehyde and niclosamide through tide diversion for more than 2 successive years may achieve a higher snail control efficiency.

摘要: [摘要] 目的 比较江滩地区纳潮引水药浸法与单纯喷洒法现场灭螺效果。方法 在2块相邻有螺江滩上分别采用纳潮引水药浸法灭螺(灭螺药为26%四聚·杀螺胺乙醇胺盐悬浮剂)与单纯26%四聚·杀螺胺乙醇胺盐悬浮剂喷洒法灭螺,在灭螺前后分别进行螺情调查并计算灭后活螺密度。结果 纳潮引水药浸法灭螺后1年和2年活螺密度下降率分别为72.19%和100.00%,单纯喷洒法灭螺后1年和2年活螺密度下降率分别为5.93%和18.15%。结论 有螺江滩纳潮引水药浸法灭螺效果明显优于单纯喷洒法灭螺,纳潮引水药浸法灭螺持续开展2年以上效果更佳。
