在这项研究中,化学成分,驱虫剂,以及从马鞭草(马鞭草科)中提取的五种植物精油(EO)的产卵抑制作用,双黄棘(Anacardiaceae),卡利斯蒙(Myrtaceae),菊科(菊科),和Hyptissuaveolens(唇齿科)对埃及伊蚊进行了评估,冈比亚按蚊,和库蚊。当在33.3µg/cm2下测试时,L.camara,S.terbinthifolia,C.viminalis,和H.odoratissimum是对Ae的有效驱避剂。埃及伊蚊(89%,91%,90%,51%的排斥性,分别),但他们对An的反感较少。冈比亚(66%,86%,59%,和49%的驱避性,分别)。有趣的是,L.卡马拉,S.terbinthifolia,C.viminalis,和H.odoatissimum对Cx表现出100%的排斥性。quinquefasciatus为33.3μg/cm2。在333μg/cm2的时间跨度生物测定中,L.camara的EO对Ae表现出100%的抵抗性。埃及伊蚊和安.冈比亚长达15分钟,对抗Cx。quinquefasciatus75分钟。产卵生物测定表明,卡马拉乳杆菌表现出最高的活性,显示85%,59%,和89%的产卵威慑对Ae。埃及伊蚊,A.冈比亚,Cx.Quinquefasciatus,分别。L.camara的主要化合物,S.terbinthifolia,和念珠菌是反式-β-石竹烯(16.7%),α-pine烯(15.5%),和1,8-桉树脑(38.1%),分别。总之,L.camara和S.terbinthifoliaEO具有天然驱蚊的潜力。
In this study, the chemical composition, repellent, and oviposition deterrent effects of five plant essential oils (EOs) extracted from Lantana camara (Verbenaceae), Schinus terebinthifolia (
Anacardiaceae), Callistemon viminalis (Myrtaceae), Helichrysum odoratissimum (Asteraceae), and Hyptis suaveolens (Lamiaceae) were evaluated against Aedes aegypti, Anopheles gambiae, and Culex quinquefasciatus. When tested at 33.3 µg/cm2, L. camara, S. terebinthifolia, C. viminalis, and H. odoratissimum were effective repellents against Ae. aegypti (89%, 91%, 90%, and 51% repellency, respectively), but they were less repellent against An. gambiae (66%, 86%, 59%, and 49% repellency, respectively). Interestingly, L. camara, S. terebinthifolia, C. viminalis, and H. odoratissimum exhibited 100% repellency against Cx. quinquefasciatus at 33.3 μg/cm2. In time-span bioassays performed at 333 μg/cm2, the EO of L. camara exhibited 100% repellence against Ae. aegypti and An. gambiae for up to 15 min and against Cx. quinquefasciatus for 75 min. The oviposition bioassays revealed that L. camara exhibited the highest activity, showing 85%, 59%, and 89% oviposition deterrence against Ae. aegypti, An. gambiae, and Cx. quinquefasciatus, respectively. The major compounds of L. camara, S. terebinthifolia, and C. viminalis were trans-β-caryophyllene (16.7%), α-pinene (15.5%), and 1,8-cineole (38.1%), respectively. In conclusion, the L. camara and S. terebinthifolia EOs have the potential to be natural mosquito repellents.
