Aphids are one of the major agricultural pests in the world. Their pest management in pepper greenhouses is based on integrated control with release of natural enemies and pesticide treatments used in specific conditions. Essential oils may be used as an eco-friendly alternative for the control of this pest. In this work, we study the repellent effect of essential oils and pure compounds against aphids by two-choice bioassays. (E)-anethole, geraniol, farnesol, and (Z)-jasmone were the most repellent compounds for Myzus persicae and Macrosiphum euphorbiae (RD₅₀ = 0.011 − 0.086 µl/cm²). Farnesol at dose of 10 µL attracts natural enemies of aphids, Aphidius colemani adults and Sphaerophoria rueppellii larvae, in y-tube olfactometer bioassays. A residual toxicity bioassay, using a computer-controlled spraying apparatus, showed a slight toxicity (< 20% mortality) against larvae of S. rueppellii when exposed to treatments of (E)-anethole, farnesol, or (Z)-jasmone individually. The foliar application of farnesol+(E)–anethole (1:1) nanoemulsions on plants infested with aphids resulted in a reduction of the population growth ratio of M. persicae (ri = − 0.78) and M. euphorbiae (ri = − 3.85). Among the tested compounds, farnesol is a promising compound to be introduced in aphid management for its potential as a repellent and aphicide, as well as an attractant of some natural enemies of this pest.

蚜虫是世界上主要的农业害虫之一。它们在胡椒温室中的害虫管理是基于对天敌的释放和特定条件下使用的农药处理的综合控制。精油可用作控制该害虫的生态友好替代品。在这项工作中，我们通过二选生物测定法研究了香精油和纯化合物对蚜虫的驱避作用。（E）茴香脑，香叶醇，法尼醇和（Z）茉莉酮是桃蚜和大戟的最强驱避性化合物（RD ₅₀  = 0.011-0.086 µl / cm ²）。剂量为10 µL的法呢醇会吸引蚜虫的天敌，y形管嗅觉仪生物测定中的蚜虫成虫和拟南芥幼虫。残余毒性的生物测定，使用计算机控制的喷射装置，呈小幅毒性（<20％的死亡率）对幼虫S. rueppellii当暴露于治疗（E） -anethole，金合欢醇，或（Z） -jasmone单独。将法尼醇+ （E）–茴香脑（1：1）纳米乳剂叶面施用在被蚜虫侵染的植物上，导致桃蚜（ri  = − 0.78）和大戟莫桑比克（ri）的种群生长率降低。 =-3.85）。在受试化合物中，法尼醇是一种有前途的化合物，因其作为驱虫剂和杀磷剂以及该害虫某些天敌的引诱剂而被潜在地引入蚜虫管理。
