用诱引物诱捕钉螺幼螺试验曾有报告。本文拟通过实验室和现场诱捕水下幼螺试验,探讨在达到基本消灭和消灭血吸虫病标准的山丘地区,诱捕水下幼螺监测残存钉螺的应用价值。 材料与方法 一、实验室诱捕幼螺试验取安徽省贵池的钉螺成螺,按文献方法繁殖幼螺。在直径21cm,高10cm的玻璃缸内装脱氯水1,000ml,水深3cm,缸底放85目/吋过筛泥浆10ml。实验前将幼螺放入缸内,任其自由活动24h后进行实验。每缸试验幼螺数25只,重复试验4缸;稻草段
Trap snail snail trapping experiments have been reported. This paper intends to trap underwater juvenile snails by laboratory and on-site investigation to explore the value of monitoring juvenile snails trapped in juvenile snails that reach the standard of eliminating and eliminating schistosomiasis. MATERIALS AND METHODS I. Laboratory snatch young snail test Take snail snail in Guichi, Anhui Province, according to the literature method to propagate snail. 1,000 ml of dechlorinated water was placed in a glass cylinder 21 cm in diameter and 10 cm in height, and the depth of water was 3 cm. The bottom of the cylinder was placed with 10 ml of sieve slurry of 85 mesh / inch. Before the experiment, the young snail into the cylinder, let its free activity 24h after the experiment. Twenty-five snails were tested per cylinder, with 4 replicates; straw
