摘  要：
采用田间接虫的方法 ,研究了江苏沿海地区不同密度的同型巴蜗牛对花荚期秋大豆的为害及产量损失。结果表明 ,大豆叶片和幼荚是同型巴蜗牛为害的主要器官 ,形成大量的破叶是花荚期大豆受害的典型症状。大豆产量损失率与花荚期幼荚受害数、蜗牛密度、瘪粒率及百粒重间存在线性相关关系。根据大豆产量损失率及防治费用等制订了花荚期秋大豆同型巴蜗牛的防治指标 :每百株 2 0头成贝 ,或者每株新被害幼荚0 .1 5个。

摘  要：
The damage and yield loss of autumn soybean caused by different densities of Bradybaena similaris at flowering and podding stage in the coastal area of Jiangsu province were studied by inoculation method, the results indicated that B. similaris mainly injured the leaf and young pod of soybean, and led to large quantities of broken leaves. There were linear correlations between the rate of yield loss and the number of injured young pod, the density of B. similaris, rate of shrunken grain, 100-grain weight. According to the rate of yield loss of soybean, control costs and so on, the control index of B. similaris at flowering and podding stage of autumn soybean was put forward as follows: 20 adults per 100 plants or 0.15 newly-injured young pod per plant.
