摘要

The study was undertaken to evaluate the adulticidal efficacy of the methanolic leaf extracts and essential oils of Chenopodium ambrosioides, Hyptis suaveolens and Lippia adoensis against adults of Anopheles gambiae . A chemical profile of each plant extracts (qualitative phytochemical screening) and essential oil (GC/MS analysis) was also determined. Doses of 125, 250, 500 and 1000 mg/bottle of plant extracts and 25, 50, 100 and 200 mg/bottle of essential oils were prepared and tested using CDC bottles. In each plant extract, alkaloids, flavonoids, saponins, tannins, phenolic groups, terpenoids, fats and oils were presents. Major chemical constituents of essential oils were thymol (27.09%), sabinene (18.93%) and 4-carene (52.88%) in L. adoensis , H. suaveolens and C. ambrosioides , respectively. L. adoensis extract (at 1000 mg/bottle) and essential oil of H. suaveolens (at 200 mg/bottle) were the most potent causing 100% mortality of An. gambiae adults, 24 h post-exposure. Methanolic extract of L. adoensis (LC_(50)= 20.20 mg/bottle) was the most effective compared to other extracts. Similarly, essential oil of H. suaveolens (LC_(50)= 5.27 mg/bottle) was revealed as the most toxic on An. gambiae adults compared to other oils. Therefore, the extracts of L. adoensis and essential oil of H. suaveolens showed a high activity and should be recommended to be promoting as natural bioinsecticides to control mosquito adults.

Adoensis萃取物(1000mg /瓶)和H.Suaveolens的精油(在200mg /瓶子)中最有效,导致100%的死亡率。 Gambiae成人,24小时后接触。与其他提取物相比,甲醇提取物(LC_(50)= 20.20mg /瓶)最有效。类似地,H. suaveolens的精油(LC_(50)= 5.27mg /瓶子)被揭示为最有毒的。冈比亚成年人与其他油相比。因此,L.Suavolens的L.Adoensis和精油的提取物表现出高活性,应该建议促进为天然生物灭菌剂来控制蚊虫成年人。
