Solutions for managing the growing populations of the snail (Rafinesque, 1833) in row crops, notably peanut ( L.), are urgently needed in the United States. This species has become a concern to the economy and food security for infesting commercial crops in U.S. southern states. In the present study, sampling, trapping, and management strategies were investigated to support a management program for in row crops. In addition, the preference of for species of row crops and weeds, used as a shelter, and snail dispersal capacity were documented. The results indicated that the ideal tools for monitoring and capturing snails are beat cloth and cardboard trap, respectively. Metaldehyde 4% bait produced effective control. Tillage was tested as an alternative cultural management tactic and produced the most promising outcomes in lowering snail populations. According to snail ecological studies, peanut and soybean are the preferred crops used as shelter over cotton and corn. Among eight common winter-growing weeds, the favored non-crop host plants are cutleaf primrose () and dandelion (). The snail field population tends to increase as early spring temperatures rise, with more snails becoming trapped in warm, humid conditions but not through heavy precipitation. This study provides ecology information on and validates tactics to manage this invasive species in row crops, in an IPM approach.
美国迫切需要解决在行间作物，尤其是花生（Arachis hypogaea L.）田中蜗牛（Rafinesque, 1833）数量不断增长的问题。该物种因在美国南部各州侵害商业作物，已对经济和粮食安全构成威胁。在本研究中，对采样、诱捕和管理策略进行了调查，以支持针对行间作物中该蜗牛的管理计划。此外，还记录了该蜗牛对用作庇护所的行间作物和杂草种类的偏好以及蜗牛的扩散能力。结果表明，监测和捕获蜗牛的理想工具分别是拍打布和纸板诱捕器。4%的聚乙醛诱饵能有效控制蜗牛数量。深耕作为一种替代的栽培管理策略进行了测试，在降低蜗牛数量方面产生了最有前景的结果。根据蜗牛生态学研究，与棉花和玉米相比，花生和大豆是蜗牛更偏好用作庇护所的作物。在八种常见的冬季生长杂草中，蜗牛最喜欢的非作物寄主植物是报春花（Primula incisa）和蒲公英（Taraxacum officinale）。随着早春气温升高，田间蜗牛数量往往会增加，在温暖潮湿的条件下会有更多蜗牛被诱捕，但暴雨不会导致这种情况。本研究提供了有关该蜗牛的生态学信息，并验证了以综合害虫管理方法在行间作物中管理这种入侵物种的策略。
