In recent times, bioprospecting for plants that show bioactive properties has yielded many chemicals that can be used in controlling mosquitoes. Crude extracts of 4 terrestrial and 3 mangrove plants were assayed against 2-3 larval instars of Aedes aegypti. Among the plants tested, Cordia curassavica showed the highest levels of activity for all the extracts tested. Azadirachta indica showed the least activity, whereas the 2 cultivars of Mangifera indica showed substantial activity for the aqueous extracts. The mangrove species proved to be relatively nontoxic to Ae. aegypti larvae when compared to the terrestrial plants. The results of this study suggest that some common plants in Trinidad may be highly effective in controlling the urban vector of yellow fever and dengue fever, Ae. aegypti.
近年来，对具有生物活性的植物进行生物勘探已产生了许多可用于控制蚊子的化学物质。对4种陆生植物和3种红树林植物的粗提物针对埃及伊蚊的2至3龄幼虫进行了测定。在所测试的植物中，刺果破布木对所有测试提取物表现出最高的活性水平。印楝的活性最低，而芒果的两个栽培品种对水提取物表现出显著活性。与陆生植物相比，红树林物种对埃及伊蚊幼虫相对无毒。这项研究的结果表明，特立尼达的一些常见植物可能对控制黄热病和登革热的城市传播媒介埃及伊蚊非常有效。
