Several studies have assessed the potential of essential oils as substitutes for synthetic pesticides, in order to counter insect resistance to commercial pesticides. Piper aduncum L. is a very common shrub in the Amazon Rainforest and in other subtropical areas. The objective of this review was to analyse the existing information on P. aduncum essential oil as a raw material for new bioproducts for sustainable pest disease management. With this review, we collected and critically analysed 59 papers, representing all the studies that aimed to evaluate the essential oil properties of this species as an insecticide, acaricide and antiparasitic. The chemical composition differs depending on the origin, although phenylpropanoid dillapiole is the most cited component, followed by myristicin, 1,8-cineole and β-ocimene. Between the acaricidal, antiparasitic and synergistic activities, the insecticidal effects are highly promising, with optimal results against the malaria vector Aedes aegypti, with an LC that ranges between 57 and 200μg/mL. Acaricidal activity has mainly been reported against Tetranychus urticae, showing an LC that ranges between 5.83 and 7.17μg/mL. Antiparasitic activity has predominately been found on Leishmania amazonensis, and antipromastigote activity has been found to be between 23.8 and 25.9μg/mL. Concerning the synergistic effect between dillapiole and synthetic insecticides, four studies on Spodoptera frugiperda found promising results with cypermethrin. In this review, we highlighted the potential of P. aduncum essential oil as a biopesticide, also focusing on the lack of information about applied research. We also provide suggestions for future investigations.
已有多项研究评估了精油作为合成农药替代品的潜力，以应对昆虫对商业农药的抗药性。蓬蘽（Piper aduncum L.）是亚马逊雨林和其他亚热带地区非常常见的灌木。本综述的目的是分析蓬蘽精油作为可持续害虫病管理的新生物制品原料的现有信息。通过本次综述，我们收集并批判性地分析了 59 篇论文，这些论文代表了所有旨在评估该物种精油作为杀虫剂、杀螨剂和驱虫剂特性的研究。化学成分因产地而异，尽管苯丙素类化合物 dillapiole 是最常被引用的成分，但紧随其后的是肉豆蔻醚、1,8-桉叶素和β-罗勒烯。在杀螨、驱虫和协同活性中，杀虫效果非常有前景，对疟疾传播媒介埃及伊蚊的最佳结果为 LC 50 在 57 到 200μg/mL 之间。杀螨活性主要针对二斑叶螨（Tetranychus urticae）报道，LC 50 范围在 5.83 到 7.17μg/mL 之间。驱虫活性主要在美洲利什曼原虫（Leishmania amazonensis）上发现，对前鞭毛体的活性为 23.8 到 25.9μg/mL。关于 dillapiole 与合成杀虫剂之间的协同作用，有四项关于草地贪夜蛾（Spodoptera frugiperda）的研究发现与氯菊酯有很好的协同增效作用。在本综述中，我们强调了蓬蘽精油作为生物农药的潜力，同时也关注到应用研究信息不足的问题。我们还为未来的研究提供了建议。
