Experiments on the leaf extract tested against three mosquito species led to 100% mortality of stage 4 Anopheles, Aedes and Culex larvae at a concentration of 0.08% within 24-48 h, whereas 100% mortality of stage 1 larvae occurred at lower concentrations: 0.0032% for Aedes aegypti, 0.016% for Culex quinquefasciatus and 0.08% for Anopheles stephensi, and was more rapid. At the end of 24 h, the highest dilution of the seed extract studied (1:200) produces a larval mortality of 100% for Anopheles and Aedes and 56% for Culex spp., when 4th instar larvae were exposed at room temperature. The comparative mortality in the control group was negligible. One hundred per cent mortality of Anopheles larvae took place by the end of 10 h, and of Aedes larvae by 17 h, at a dilution of 1:200 with water.
对三种蚊虫进行的叶提取物实验表明，在浓度为0.08%时，4龄按蚊、伊蚊和库蚊幼虫在24至48小时内死亡率达100%，而1龄幼虫在较低浓度下死亡率即达100%：埃及伊蚊为0.0032%，致倦库蚊为0.016%，斯氏按蚊为0.08%，且死亡速度更快。在24小时结束时，当4龄幼虫在室温下接触所研究的种子提取物最高稀释度（1:200）时，按蚊和伊蚊幼虫死亡率达100%，库蚊属幼虫死亡率为56%。对照组的死亡率可忽略不计。在用水稀释至1:200时，按蚊幼虫在10小时结束时死亡率达100%，伊蚊幼虫在17小时结束时死亡率达100%。
