Intercropping of aromatic plants provides an environmentally benign route to reducing pest damage in agroecosystems. However, the effect of intercropping on natural enemies, another element which may be vital to the success of an integrated pest management approach, varies in different intercropping systems. Rosemary, L. (Lamiaceae), has been reported to be repellent to many insect species. In this study, the impact of sweet pepper/rosemary intercropping on pest population suppression was evaluated under greenhouse conditions and the effect of rosemary intercropping on natural enemy population dynamics was investigated. The results showed that intercropping rosemary with sweet pepper significantly reduced the population densities of three major pest species on sweet pepper, , , and , but did not affect the population densities of their natural enemies, the predatory bug, , or parasitoid, . Significant pest population suppression with no adverse effect on released natural enemy populations in the sweet pepper/rosemary intercropping system suggests this could be an approach for integrated pest management of greenhouse-cultivated sweet pepper. Our results highlight the potential of the integration of alternative pest control strategies to optimize sustainable pest control.
间作芳香植物为减少农业生态系统中的害虫危害提供了一条环境友好的途径。然而，间作对天敌的影响，这可能是综合虫害管理方法成功的另一个关键因素，在不同的间作系统中有所不同。迷迭香，唇形科，据报道对许多昆虫种类有驱避作用。在本研究中，在温室条件下评估了甜椒/迷迭香间作对害虫种群抑制的影响，并研究了迷迭香间作对天敌种群动态的影响。结果表明，甜椒与迷迭香间作显著降低了甜椒上三种主要害虫物种（烟粉虱、棉蚜和蓟马）的种群密度，但对它们的天敌（捕食性蝽类和寄生性天敌）的种群密度没有影响。甜椒/迷迭香间作系统中显著抑制害虫种群且对释放的天敌种群无不利影响，表明这可能是温室栽培甜椒综合虫害管理的一种方法。我们的结果突出了整合替代害虫控制策略以优化可持续害虫控制的潜力。
