The peach fruit fly (), a significant polyphagous pest, poses a considerable threat to fruit crops across its expanding range. Although climate change significantly impacts pest populations, its effects on remain understudied. This research examined population dynamics across two distinct Egyptian ecological zones (Sohag and Ismailia Governorates) from 2013-2023 using pheromone traps and climate data. Results revealed significant spatial and temporal variations in abundance patterns. Both regions displayed a unimodal distribution, with Sohag exhibiting a distinct peak during September to November, whereas Ismailia showed a broader peak period spanning from August to December. Temperature significantly influenced population levels while precipitation showed no significant effect. Similarly, our results indicated increasing population trends in both regions despite no significant long-term temperature changes. These findings suggest that factors beyond temperature alone, such as host fruit availability, regional environmental variations, and potentially evolving agricultural practices, drive population growth, highlighting the need for comprehensive, climate-responsive pest management strategies that account for regional variations.
桃实蝇是一种重要的多食性害虫，在其不断扩大的分布范围内，对水果作物构成了相当大的威胁。尽管气候变化对害虫种群有重大影响，但其对桃实蝇的影响仍未得到充分研究。本研究利用性诱捕器和气候数据，对2013年至2023年埃及两个不同生态区（索哈杰省和伊斯梅利亚省）的桃实蝇种群动态进行了研究。结果显示，桃实蝇的丰度模式存在显著的空间和时间变化。两个地区均呈现单峰分布，索哈杰在9月至11月出现明显峰值，而伊斯梅利亚的峰值期则从8月持续到12月。温度对种群数量有显著影响，而降水则无显著影响。同样，我们的结果表明，尽管长期温度没有显著变化，但两个地区的种群数量均呈上升趋势。这些发现表明，除温度外，诸如寄主果实可用性、区域环境差异以及可能不断演变的农业实践等因素推动了桃实蝇种群增长，凸显了制定全面的、应对气候变化的害虫管理策略以考虑区域差异的必要性。
