The invention provides a method for ecologically controlling pests in orchards. The method includes establishing a composite ecosystem of a fruit tree-graminaceous plant compound second plant in an orchard, and the second plant is an iris plant, a liliaceous plant or a creeping vine plant. The method can increase biodiversity of the orchard and enable natural enemies to multiply in the field, thereby controlling and reducing number of pest populations, achieving a purpose of reducing frequency and dosage of chemical pesticides, and achieving ecological and fruit safety. In addition, the methodcan reduce cutting frequency on the basis of not influencing pest control effect, and only need to cut 2 to 3 times a year, and reduce labor costs. 本发明提供一种生态控制果园害虫的方法，所述方法包括在果园中建立果树-禾本科植物复合第二植物的复合生态体系，所述第二植物为鸢尾科植物、百合科植物或匍匐藤本植物。本发明的方法可以增加果园生物多样性，使天敌在田间自然增殖，从而控制和减少害虫种群数量，达到减少化学农药使用次数和用量的目的，实现生态和果品安全。而且本发明的方法可以在不影响控害效果的基础上减少刈割次数，一年刈割2～3次即可，减少劳动成本。
