A study of the behavioral responses of Aedes aegypti and Anopheles minimus to 3 Cambodian plant extracts at 3 different concentrations (1%, 2.5%, and 5%) was performed using an excito-repellency test system. These 3 plants were Strophanthus scandens, Capparis micracantha, and Dioscorea hispida, selected according to traditional healer's knowledge, bibliographic studies and market surveys. Results showed that S. scandens leaves' hexane extract was the only one to exert repellency against Ae. aegypti with 23.3% of escaped mosquitoes at a concentration of 5%. Capparis micracantha was responsible for an irritant activity against An. minimus with 20.2% of escaped mosquitoes at a concentration of 2.5% and 22.8% escaping at a concentration of 5%. Dioscorea hispida showed an irritant activity on both mosquito species with 23.2% of escaped Ae. aegypti at a concentration of 5% and about 20% of escaped An. minimus at 2.5% and 5%. This is the first report on the irritant and repellent activities of S. scandens , D. hispida , and C. micracantha against mosquito species.
利用兴奋驱避测试系统，对埃及伊蚊和微小按蚊在3种不同浓度（1%、2.5%和5%）的3种柬埔寨植物提取物中的行为反应进行了研究。这3种植物分别是毒毛旋花、小刺山柑和白薯莨，它们是根据传统治疗师的知识、文献研究和市场调查挑选出来的。结果表明，毒毛旋花叶片的己烷提取物是唯一一种对埃及伊蚊具有驱避作用的提取物，在浓度为5%时，有23.3%的蚊子逃脱。小刺山柑对微小按蚊具有刺激活性，在浓度为2.5%时，有20.2%的蚊子逃脱，在浓度为5%时，有22.8%的蚊子逃脱。白薯莨对这两种蚊子都表现出刺激活性，在浓度为5%时，有23.2%的埃及伊蚊逃脱，在浓度为2.5%和5%时，约有20%的微小按蚊逃脱。这是关于毒毛旋花、白薯莨和小刺山柑对蚊子的刺激和驱避活性的首次报道。
