消灭钉螺是消灭血吸虫病的重要关键之一,国内学者曾对河沟湖沼等类型地区的灭螺方法进行过广泛的研究,并取得一定的就成,但对田内钉螺的消灭方法研究者为数尚少,因此于1958年春选择了本省巢县泮汤乡圩区水稻田作为现场,利用药物和人工等方法进行灭螺研究,企图为今后大规模消灭田中钉螺提供参考.研究方法及其结果一、钉螺密度及死亡率调查:1.田中钉螺密度及自然死亡率的调查:每块
Elimination of snails is one of the most important factors in the elimination of schistosomiasis. Domestic scholars have conducted extensive research on snail-killing methods in such areas as Hegou Lake and have made some achievements. However, there are still a few researchers on methods of eliminating snails in the field Therefore, in the spring of 1958, paddy fields in Panxian Township, Chao County of our province were chosen as the site for the study of snail control by means of drugs and artificial methods in order to provide reference for the large-scale elimination of snails in the field in the future in 1958. Methods and Results I. Snail Density and Mortality Surveys: 1. Survey of Oncomelania density and natural mortality in Tanaka: each
