对苹果园中的害虫进行预测防控，为天水苹果园虫害防治方案的制定提供科学依据。 2022 — 2023年在甘肃省天水市果树研究所苹果品种试验园利用性诱剂诱捕的方法监测梨小食心虫、桃小食心虫、苹小卷叶蛾、金纹细蛾、绿盲蝽5种苹果树主要害虫发生动态。结果表明， 5种害虫的年度种群发生量2023年高于2022年。不同种群害虫总诱捕量有差异，其中金纹细蛾发生量最大，梨小食心发生量次之，桃小食心虫和绿盲蝽发生量较少，苹小卷叶蛾最少。金纹细蛾、梨小食心虫、苹小卷叶蛾3种害虫在苹果生长期年内有4次发生高峰，桃小食心虫有3次发生高峰；而绿盲蝽在2022年有2次发生高峰、2023年有4次发生高峰。由此可见，金纹细蛾梨、小食心虫、桃小食心虫、苹小卷叶蛾、绿盲蝽等5种害虫为天水苹果园主要害虫种类。

To enable the prediction and control of insect pests in apple orchards and provide a scientific basis for pest management strategies in Tianshui, this study monitored the population dynamics of 5 major apple tree pests using sex pheromone trapping in the apple cultivar trial orchard of Tianshui Institute of Pomology, Gansu Province, from 2022 to 2023. The monitored pests included Grapholita molesta, Carposina niponensis, Adoxophyes orana, Phyllonorycter ringoniella, and Lygocoris lucorum. Results showed that the total annual population levels of the 5 pests were higher in 2023 than in 2022. Among them, P. ringoniella had the highest total trap count, followed by C. niponensis, while G. molesta and L. lucorum were less abundant, and A. orana was the least abundant. P. ringoniella, C. niponensis, and A. orana showed 4 peak occurrences during the apple growing season, while G. molesta showed 3. L. lucorum exhibited 2 peaks in 2022 and 4 peaks in 2023. These findings indicate that P. ringoniella, C. niponensis, G. molesta, A. orana, and L. lucorum are the major insect pest species in apple orchards of Tianshui.
