Fifty local medicinal, agricultural and wild growing deciduous plants, representing 49 species, 46 genera and 22 families, were screened as water extracts at 1:1000 concentration for molluscicidal activity against Biomphalaria pfeifferi in Machakos District, Kenya. Forty-seven of the 50 (94%) plants and 106 of the 134 (79%) plant materials (roots, stems, leaves, fruits, flowers and seeds) were molluscicidal. The leaves of Pappea capensis (Sapindaceae), Steganotaenia araliacea (Umbelliferae), Zornia setosa subsp. obvata (Papilionaceae) and Terminalia kilimandscharica (Combretaceae), the flower pods of Hyptis pectinata (Labiatae), the seeds of Acacia nilotica (Mimosaceae) and the fruits and roots of Solanum nigrum (Solanaceae) gave 100% kill. Another 15 species produced mortality rates between 53% and 87%. Plants were evaluated for possible use in local snail control programmes by considering their growing characteristics, habitat requirements, toxicity in non-target organisms, abundance in the study area and competing uses.
对肯尼亚马查科斯区的50种当地药用、农业和野生落叶植物进行了筛选，这些植物代表49个物种、46个属和22个科，将其制成浓度为1:1000的水提取物，以检测对费氏拟钉螺的杀螺活性。50种植物中的47种（94%）以及134种植物材料（根、茎、叶、果实、花和种子）中的106种具有杀螺活性。南非番荔枝（无患子科）、总序桂竹香（伞形科）、短柄丁癸草亚种倒卵叶丁癸草（豆科）和东非榄仁（使君子科）的叶子、具齿香科科（唇形科）的花荚、阿拉伯金合欢（豆科）的种子以及龙葵（茄科）的果实和根的杀螺率达100%。另外15个物种的死亡率在53%至87%之间。通过考虑植物的生长特性、栖息地要求、对非目标生物的毒性、在研究区域的丰富程度以及竞争用途，对这些植物在当地蜗牛控制计划中的潜在用途进行了评估。
