Abstract

In this study, the chemical composition, repellent, and oviposition deterrent effects of five plant essential oils (EOs) extracted from (Verbenaceae), (Anacardiaceae), (Myrtaceae), (Asteraceae), and (Lamiaceae) were evaluated against , , and . When tested at 33.3 µg/cm, , , , and were effective repellents against (89%, 91%, 90%, and 51% repellency, respectively), but they were less repellent against (66%, 86%, 59%, and 49% repellency, respectively). Interestingly, , , , and exhibited 100% repellency against at 33.3 μg/cm. In time-span bioassays performed at 333 μg/cm, the EO of exhibited 100% repellence against and for up to 15 min and against for 75 min. The oviposition bioassays revealed that exhibited the highest activity, showing 85%, 59%, and 89% oviposition deterrence against , , and , respectively. The major compounds of , , and were -β-caryophyllene (16.7%), α-pinene (15.5%), and 1,8-cineole (38.1%), respectively. In conclusion, the and EOs have the potential to be natural mosquito repellents.

摘要

在这项研究中，评估了从（马鞭草科）、（漆树科）、（桃金娘科）、（菊科）和（唇形科）中提取的五种植物精油（EOs）的化学成分、驱避和产卵驱避效果。当在 33.3µg/cm 下测试时，、、、和对（89%、91%、90%和 51%的驱避率）有效，但对（66%、86%、59%和 49%的驱避率）的驱避效果较差。有趣的是，、、、和在 33.3µg/cm 时对表现出 100%的驱避率。在 333µg/cm 的时间跨度生物测定中，精油对和表现出 100%的驱避作用，持续长达 15 分钟，对持续 75 分钟。产卵生物测定表明，表现出最高的活性，对、和分别显示 85%、59%和 89%的产卵驱避率。、、和的主要化合物分别为 -β-石竹烯（16.7%）、α-蒎烯（15.5%）和 1,8-桉叶油醇（38.1%）。总之，和精油具有成为天然驱蚊剂的潜力。
