Abstract Non-host plants applied to crops are expected to repel searching adults and thereby to reduce egg laying in order to achieve pest management. In a field experiment, an increase in the number of herbivores adapting and ovipositing on non-host plants could reduce the potential for polycultures to control pests. We intercropped rows of apple trees with aromatic plants to examine effects of non-host plants on the distribution of Lyonetia prunifoliella (Hubner). We found a phenomenon that L. prunifoliella distributed over non-host plant in the second year, not in the first year. As distribution of L. prunifoliella changed to non-host plants, at the same time, its parasitic natural enemies increased due to intercropping with aromatic plants. Changes in single or blended volatile organic compounds (VOCs) from aromatic plants altered the distribution of Lepidoptera insects and parasitic wasps (Eulophidae and Anagyrus dactylopii) in canopy, which directly caused L. prunifoliella to transfer from apple trees to aromatic plants, stimulating the ability of adaptation (recognizing and experiencing) to non-host plants. Altering the habitat may be an effective addition to integrated pest management (IPM) strategies.

挥发性有机化合物 (VOC) 调节果园生态系统中鳞翅目昆虫的空间分布

摘要 应用于作物的非寄主植物有望击退寻找成虫，从而减少产卵以实现病虫害管理。在田间试验中，在非寄主植物上适应和产卵的食草动物数量的增加可能会降低混养控制害虫的潜力。我们将一排排苹果树与芳香植物间作，以检查非寄主植物对 Lyonetia prunifoliella (Hubner) 分布的影响。我们发现L. prunifoliella 在第二年而不是第一年分布在非寄主植物上的现象。随着夏枯草向非寄主植物的分布转变，同时由于与芳香植物间作，其寄生天敌增多。芳香植物单一或混合挥发性有机化合物（VOCs）的变化改变了鳞翅目昆虫和寄生蜂（Eulophidae和Anagyrus dactylopii）在冠层中的分布，直接导致L. prunifoliella从苹果树转移到芳香植物，刺激了其能力对非寄主植物的适应（识别和体验）。改变栖息地可能是有害生物综合管理 (IPM) 策略的有效补充。
