Mosquitoes are one of the most lethal animals in the world and transmit many dangerous human pathogens, causing millions of deaths each year. The search for modern and better mosquito control is an endless effort almost all over the world. Phytochemicals are promising biological agents for getting rid of pests that are harmful to human and animal health and crops, they are inexpensive, biodegradable, and have diverse modes of action. The efficacy of acetone and hexane leaf extracts of and was investigated against the 2nd and 4th larvae and pupae of two vectors, and . The results showed the obvious effect extract on the mortality of mosquito larvae, the reduction of female eggs, and a higher mortality rate in sunlight than in shadow (fluorescein). Data from field trials revealed that extracts had the greatest effect on larval reduction, reaching 89.8% in 24 h and having a 12-day stability. Polyethylene glycol, sesquiterpenes, and fatty acids were the most common compounds found in and , respectively. The acacia plant had promising larvicidal activity, safe and effective alternative to chemical insecticides.
蚊子是世界上最致命的动物之一，传播许多危险的人类病原体，每年导致数百万人死亡。在世界各地，寻找现代且更好的蚊虫控制方法是一项永无止境的努力。植物化学物质是有前景的生物制剂，可用于消除对人类、动物健康及农作物有害的害虫，它们价格低廉、可生物降解且作用方式多样。研究了[植物名称1]和[植物名称2]的丙酮和己烷叶提取物对两种病媒[病媒名称1]和[病媒名称2]的二龄和四龄幼虫及蛹的效果。结果表明，[提取物名称]提取物对蚊虫幼虫死亡率、雌蚊产卵量减少有显著影响，且在阳光下的死亡率高于在阴影（荧光素）下。田间试验数据显示，[提取物名称]提取物对幼虫减少效果最佳，24小时内达到89.8%，且具有12天的稳定性。聚乙二醇、倍半萜和脂肪酸分别是在[植物名称1]和[植物名称2]中发现的最常见化合物。阿拉伯金合欢植物具有良好的杀幼虫活性，是化学杀虫剂安全有效的替代品。
