设置假螺点查螺已有报道,在监测地区布放螺壳后查螺,以提高查螺质量。我们在基本消灭和消灭血吸虫病的山丘地区设置假螺点查螺,探讨用假螺点检出率作为调查残存螺点的质量控制指标。 材料与方法 一、螺壳:死钉螺壳口内侧标记褐色漆。 二、方法:在常规查螺前,根据当地钉螺分布的特点,在查螺环境的水线以上或地面上0.33m宽的范围内布放螺壳,田水缺、渗水田后壁等处适量

Set the false snail check snail has been reported in the monitoring area after the placement of snail check snail, in order to improve snail quality. We set the false snake check in the area where the schistosomiasis was basically eliminated and eliminated. The detection rate of the false snake was used as the quality control index for investigating the remaining snails. Materials and methods First, the shell: dead nail shell mouth mark the brown paint inside. Second, the method: before the routine snail, according to the characteristics of the local snail distribution, Chayou environment above the waterline or the ground within the 0.33m wide distribution of screw shell, lack of water, infiltration of the field behind the wall, etc. amount
