Plant extracts can provide a viable alternative to controlling many crop pests. This study sought to assess the efficacy of vegetable extracts of the unripe fruits of (yerba maté) for chemical control of the channeled apple snail () and of non-target species as the South American catfish () under laboratory conditions. In , the LC of the decoction extract was 31.39 mg.L and the LT was over 26 h. The LC of the butanol extract was 24.75 mg.L and the LT was in the range of 28 to 32 h. In juvenile , the LC of the decoction was 17.98 mg.L and the LT was in the range of 10-12 h. These extracts are particularly attractive considering the source of compounds and their effectiveness as molluscicides.
植物提取物可以为控制许多作物害虫提供可行的替代方法。本研究旨在评估未成熟的马黛茶果实的蔬菜提取物作为化学控制渠道苹果蜗牛（）和非目标物种（如南美的鲶鱼）的功效。在实验室条件下，煎剂提取物的 LC 为 31.39 mg.L，LT 超过 26 小时。丁醇提取物的 LC 为 24.75 mg.L，LT 范围在 28 到 32 小时之间。在幼年鲶鱼中，煎剂的 LC 为 17.98 mg.L，LT 范围在 10-12 小时之间。考虑到化合物的来源及其作为软体动物杀虫剂的有效性，这些提取物特别有吸引力。
