The current study was carried out to evaluate eco-friendly extracts of an invasive weed; Eichhornia crassipes (Mart.) Solms (Pontederiaceae) for controlling Agrotis ipsilon (Hufn.) (Lepidotera: Noctuidae). The insecticidal and biological activities of the whole plant extracts with different polarity solvents (petroleum ether, acetone, and absolute ethanol) were investigated. The extracts were evaluated against the 2^nd larval instars of A. ipsilon. The results revealed that acetone fraction extract was the most effective extract with the lowest LC₅₀ value (240 mg/L). The larval mortality percentage increased by elevating concentrations of all tested extracts. Pupation and adult emergence percentages were inversely proportional with the concentration of all tested extracts. There was a disturbance in both the adult malformation and sex ratios. Furthermore, the spectrophotometric testing of the most promising extracts (acetone and ethanol fractions) on some biochemical parameters (total body metabolites, acid and alkaline phosphatases, aminotransferase activities, and kidney function) in the serum of albino rats showed non-toxic effects on mammals. Therefore, acetone and ethanol fraction extracts of E. crassipes were considered promising eco-friendly insecticidal alternatives in (Integrated Pest Management) IPM programs to control A. ipsilon worldwide.

目前的研究是为了评估入侵杂草的环保提取物；Eichhornia crassipes (Mart.) Solms (Pontederiaceae) 用于控制Agrotis ipsilon (Hufn.) (Lepidotera: Noctuidae)。研究了具有不同极性溶剂（石油醚、丙酮和无水乙醇）的全植物提取物的杀虫和生物活性。将萃取物靠在2评价^第二龄幼虫的A.地老虎。结果表明，丙酮馏分提取物是最有效的提取物，LC ₅₀最低值 (240 毫克/升)。通过提高所有测试提取物的浓度，幼虫死亡率百分比增加。化蛹和成虫出现百分比与所有测试提取物的浓度成反比。成人畸形和性别比例均存在紊乱。此外，对白化大鼠血清中一些生化参数（全身代谢物、酸性和碱性磷酸酶、转氨酶活性和肾功能）的最有希望的提取物（丙酮和乙醇部分）的分光光度法测试显示出对哺乳动物无毒作用. 因此，E. crassipes 的丙酮和乙醇部分提取物被认为是（综合害虫管理）IPM 程序中控制A 的有前途的环保杀虫替代品。. ipsilon全球。
