Ninety-six ethanolic extracts from various parts of 84 Thai plant species were tested for their larvicidal activity against Aedes aegypti mosquitoes. Extracts from Rhinacanthus nasutus, Derris elliptica, Trigonostemon reidioides, Homalomena aromatica, Stemona tuberosa and Acorus calamus possessed high larvicidal activity, with LC50 values between 16.0 and 48.2 mg/l. Petroleum ether (PE) and methanol (MeOH) extracts were tested for their larvicidal activity against 4 mosquito vector species. The PE extract of R. nasutus exhibited larvicidal effects against Ae. aegypti, Culex quinquefasciatus, Anopheles dirus and Mansonia uniformis with LC50 values between 3.9 and 11.5 mg/l, while the MeOH extract gave LC50 values of between 8.1 and 14.7 mg/l. D. elliptica PE extract showed LC50 values of between 11.2 and 18.84 mg/l and the MeOH extract exhibited LC50 values between 13.2 and 45.2 mg/l.
对来自84种泰国植物不同部位的96种乙醇提取物进行了抗埃及伊蚊幼虫活性测试。长穗爵床、鱼藤、红背山麻杆、芳香千年健、百部和菖蒲的提取物具有较高的杀幼虫活性，LC50值在16.0至48.2毫克/升之间。测试了石油醚（PE）提取物和甲醇（MeOH）提取物对4种蚊虫媒介的杀幼虫活性。长穗爵床的PE提取物对埃及伊蚊、致倦库蚊、大劣按蚊和东乡伊蚊表现出杀幼虫作用，LC50值在3.9至11.5毫克/升之间，而MeOH提取物的LC50值在8.1至14.7毫克/升之间。鱼藤的PE提取物LC50值在11.2至18.84毫克/升之间，MeOH提取物的LC50值在13.2至45.2毫克/升之间。
