Abstract:

 Objective   To evaluate the molluscicidal effect of Rongbao Powder in schistosomiasis
mountainous areas.  Methods   A total of 64 134 mz in Yuanping Village, Duoyue Township and 50
934 m2 in Wuxing Village, Funiu Township with exempting ploughing farmland of Meishan City,
Sichuan Province were sampled as the study group. Rongbao Powder mixtured with fine soil was
sprinkled in the field of the study group.  With the sameness of landform and vegetation, 36 600 m2
of Yuanping Village and 4 333 m2 0f Wuxing Village were sampled as the control group. There was
no snail control measure in the canals and ditches of study and control groups in Yuanping Village,
and niclosamide mud was used in those places of study and control groups in Wuxing Village. The
appearance rate of snail frames, the change of average density of living snails and the result of envi-
ronment intervention were observed, and the fertilization and harvest of the field were investigated.
Results  As the short- or long-term results, the molluscicidal effectiveness of Rongbao Powder,
the study group in Wuxing Village, Funiu Township was better than that in Yuanping Village,
Duoyue Township. After one planting duration, the appearance rate of snail frames of Yuanping
 Village's study group declined by 68. 64%  (X2 =136. 58,P<0.01),  the average density of living
 snails of Yuanping Village decreased by 35. 78% (Z = - 2. 22,  P<0. 05),  the appearance rate of
 snail frames of Wuxing Village reduced by  97. 03% (X2 = 349. 68,P<0.01),  the average density of
 living snails of Wuxing Village reduced by 96. 64%  (Z = - 7. 65,P<0.01).  On the cost-benefit,

摘要:

目的评价“荣宝”在山丘型血吸虫病流行区的灭螺效果。方法选择四川省眉山市多悦镇园坪村64 134 m2、富牛乡五星村50 934 mz的自然免耕栽培的稻田,采用“荣宝”与干细土混匀后撒施,同时以地形和植被相似的园坪村36 600 mz、五星村4 333 mZ的免耕田作为对照,园坪施药组及对照组田间沟渠未采取灭螺措施,五星施药组及对照组田间沟渠采用氯硝柳胺泥敷。观察各组有螺框出现率、活螺平均密度的变化情况及外环境干扰的影响,了解农作物的施肥和收成情况。结果 “荣宝”的灭螺效果,无论近期或远期五星村实验组均好于园坪村,经过一个种植季节,园坪实验组有螺框出现率下降了68. 6426%(X2 =136. 58,P<0.01),活螺平均密度下降了35. 78% (Z=-2. 22,P<0.05);五星实验组的有螺框出现率下障了97. 03% (X2=349. 68,P<O. Ol),活螺平均密度下降了96.64%(2=-7.65,P<0.01)。“荣宝”试验组的费用效益比对照组每平方米可以增加收入0. 06元。结论“荣宝”灭螺适合在免耕田里施用,具有一定的杀灭田间钉螺的作用,同时增产和减少开支。在使用“荣宝”田间灭螺时应同时进行沟渠钉螺的处理。
