Aphids are major agricultural pests, feeding on plant sap and transmitting viruses to economically important crops. The use of synthetic pesticides is increasingly restricted due to stricter regulations aimed at protecting both human and environmental health. To address this challenge, we investigated the potential of essential oils (EOs) extracted from rosemary ( Spenn.), laurel ( L.), and cypress ( L.) as alternatives to synthetic insecticides, while ensuring compatibility with biological control strategies. The EOs were extracted via hydrodistillation, diluted in acetone, and tested against the aphid and its natural predator, the hoverfly (). Aphid mortality was dose-dependent, reaching 85% with rosemary EO, 83% with laurel, and 81% with cypress. In contrast, hoverfly larvae mortality remained low, with a maximum of 20%, which could largely be attributed to the solvent used in the assays. These promising results support further research to develop effective EO-based tools for integrated pest management.
蚜虫是主要的农业害虫，以植物汁液为食，并将病毒传播给具有重要经济价值的作物。由于旨在保护人类和环境健康的更严格法规，合成农药的使用受到越来越多的限制。为应对这一挑战，我们研究了从迷迭香（Spenn.）、月桂（L.）和柏树（L.）中提取的精油作为合成杀虫剂替代品的潜力，同时确保与生物防治策略兼容。通过水蒸馏法提取精油，用丙酮稀释，并针对蚜虫及其天敌食蚜蝇（）进行测试。蚜虫死亡率呈剂量依赖性，迷迭香精油处理的死亡率达到85%，月桂精油为83%，柏树精油为81%。相比之下，食蚜蝇幼虫的死亡率仍然很低，最高为20%，这在很大程度上可归因于试验中使用的溶剂。这些有前景的结果支持进一步开展研究，以开发基于精油的有效病虫害综合管理工具。
