研究了4种海百合的甲醇和乙酸乙酯(EA)提取物对黄热病幼虫(埃及伊蚊)的杀虫活性和对亚洲虎成蚊(Aedes Albopictus)的驱避作用。24小时最小抑菌浓度数据显示，木兰花和斑纹夜蛾提取物对蚊子幼虫的杀灭活性最强，为12.5 ppm。4种海百合提取物的毒性由大到小依次为：木兰(12.5 ppm)、斑百合(12.5 ppm)、多裂海百合(100 ppm)、科曼蒂纳。(百万分之二百 )。此外，乙酸乙酯和甲醇作为萃取剂的毒性没有显著差异。最低抑菌浓度为12.5ppm，是一种有希望的杀虫剂铅。 。驱避性研究结果表明，EA是一种较好的驱避剂，而甲醇是较好的驱避剂。海百合提取物的驱避力由大到小依次为科曼蒂纳。甲醇(ED50为0.32%)，其次是木兰花(ED50为0.38%)、多裂青霉(ED50为0.57%)、斑叶金鱼(ED50为0.76%)、多裂金鱼(ED50为1.25%)和木兰花(ED50为1.67%)。ED50 <；0.5%的化合物被认为是一种很有前途的驱避剂。在所研究的海百合中，两种海百合均为科曼蒂纳(Comansina sp.)和木兰花夜蛾具有良好的毒性和驱避性，有进一步开发为灭蚊药物的潜力。
The methanol and ethyl acetate (EA) extracts of four species of sea lily (Himerometra magnipinna, Comaster multifidus, Comanthina sp., and Comatella maculata) were evaluated for their insecticidal activity against Yellow-fever mosquito larvae (Aedes aegypti) and their repellency against adult Asian Tiger mosquitoes (Aedes albopictus). The 24-hr minimum inhibition concentration (MIC) data revealed that the extracts from H. magnipinna and the C. maculata were the most active, killing mosquito larvae at 12.5 ppm. The toxicity of the extracts from these four sea lilies in descending order was H. magnipinna (12.5 ppm), C. maculata (12.5 ppm), C. multifidus (100 ppm), and Comanthina sp. (200 ppm). Furthermore, no significant difference in toxicity was found using either EA or methanol as the extraction solvent. The MIC at 12.5 ppm is promising as an insecticide lead. The repellency study results show that EA is a better solvent for one species (H. magnipinna), but the methanol is a better solvent overall. The repellency of these sea lily extracts in descending order was Comanthina sp. MeOH (ED50 at 0.32%), followed by H. magnipinna EA (ED50 at 0.38%), C. multifidus MeOH (ED50 at 0.57%), C. maculata MeOH (ED50 at 0.76%), C. multifidus EA (ED50 at 1.25%), and H. magnipinna MeOH (ED50 at 1.67%). A compound with ED50 <0.5% is considered to be a promising repellant. Among the studied sea lilies, both Comanthina sp. and H. magnipinna have potential to be further developed as mosquito control agents due to their favorable toxicity and repellency.
