The golden mussel Limnoperna fortunei (Dunker 1857) is one of the most distributed Nuisance Invasive Species (NIS) in South America, and a threat of great concern for the industry of the area. In this study, we carried out toxicity tests made with a Neem's oil solution with L. fortunei larvae and benthonic adults (7, 13 and 19 ± 1 mm). Tests with non-target species (Daphnia magna, Lactuca sativa and Cnesterodon decemmculatus) were also made with the aim to evaluate the potential toxicity of the Neem's solution in the environment. The LC(100) of Neem's solution obtained for larvae was 500 µl/L, a value much higher than the one obtained for D. magna and C. decemmaculatus. Thus, we recommend that it should not be used in open waters. However, since the adults were killed in 72 h and the larvae in 24 h, this product can be used in closed systems, in man-made facilities.
金贻贝（Limnoperna fortunei，邓卡1857年命名）是南美洲分布最广的有害入侵物种之一，对该地区的相关产业构成了极大威胁。在本研究中，我们用印楝油溶液对金贻贝幼虫和底栖成虫（体长分别为7、13和19±1毫米）进行了毒性测试。同时，我们还对非目标物种（大型溞、生菜和九间始丽鱼）进行了测试，以评估印楝溶液在环境中的潜在毒性。印楝溶液对幼虫的LC(100)为500微升/升，该数值远高于大型溞和九间始丽鱼的LC(100)。因此，我们建议不要在开放水域使用该溶液。然而，由于成虫在72小时内死亡，幼虫在24小时内死亡，所以该产品可用于人造设施的封闭系统中。
