Secondary metabolites from Dysoxylum malabaricum and Dysoxylum beddomei were tested against mature and immature stage of the mosquito vector Anopheles stephensi under laboratory conditions. The triterpenes 3beta,24,25-trihydroxycycloartane and beddomeilactone from D. malabaricum and D. beddomei showed strong larvicidal, pupicidal and adulticidal activity. They also affected the reproductive potential of adults by acting as oviposition deterrents. The highest concentration tested (10 ppm) of both compounds evoked more than 90% mortality and oviposition deterrence.
在实验室条件下，对来自毛瓣楝（Dysoxylum malabaricum）和贝德楝（Dysoxylum beddomei）的次生代谢产物针对蚊媒斯氏按蚊（Anopheles stephensi）的成熟和未成熟阶段进行了测试。来自毛瓣楝和贝德楝的三萜类化合物3β,24,25 - 三羟基环阿尔廷烷和贝德楝内酯表现出很强的杀幼虫、杀蛹和杀成虫活性。它们还通过作为产卵抑制剂影响成虫的繁殖潜力。两种化合物测试的最高浓度（10 ppm）引起了超过90%的死亡率和产卵抑制。
