摘要
室内观察证明:稻草对钉螺有较好的诱螺效果,且对阴性、感染性钉螺和成、幼螺的诱获率均无显著差异。以此为依据,用稻草帘诱螺法,可相对地了解涨水期内草洲的螺情。本文报道:用石块固定编织草帘,使之沉入水底,以塑料泡沫为浮标的水下诱螺方法方便、易行。诱获率以诱螺时间14h、季节在8月份为最高。
As a result of observation in lab. ,it showed that the rice straw attracted snail well,it at-tracted uninfected and infected snails, and adult and young snails respectively without singnificant difference. On this basis,we can investigate the snails under water by rice straw curtains during water raising season. This paper reported that the method for weaving rice straw curtain fixed by stone,and using foamed plastics as buoy were easy and convenient. The rate of snail-attraction was highest when it took 14 hours ,especially in August.
