A dichloromethane extract of the seeds of the molluscicidal west African legume Millettia thonningii was tested for ovicidal activity toward Biomphalaria glabrata egg masses. The extract was found to be highly ovicidal at concentrations as low as 5 mg/L. Embryonic development of the snails in egg masses was monitored using photomicrographs from which embryonic diameters were estimated. Such measurements revealed that ovicidal effects were developmentally stage specific and normally induced a curtailment of development during the gastrula to trochophore transition.
对杀螺西非豆科植物托宁鱼藤（Millettia thonningii）种子的二氯甲烷提取物进行了针对光滑双脐螺（Biomphalaria glabrata）卵块的杀卵活性测试。发现该提取物在低至5毫克/升的浓度下具有高度杀卵活性。使用显微照片监测卵块中蜗牛的胚胎发育，通过这些照片估计胚胎直径。这些测量结果表明，杀卵作用具有发育阶段特异性，通常会在原肠胚向担轮幼虫转变期间导致发育缩短。
