摘要

摘要:黄桃蛾(Conogethes punctiferalis, YPM)和核桃举升蛾(Atrijuglans hetaohei, Yang, WLM)是核桃(核桃属)的蛀虫，由于占据相同的生态位而表现出竞争关系。然而，气候变化、农业管理和不合理的农药使用对这些昆虫造成的损害的影响尚不清楚。本研究的长期野外监测显示，自2018年以来，核桃上的YPM种群数量已经超过了WLM，这表明YPM以前被认为是一种次要害虫，现在正在成为一种主要害虫。此外，实地调查结果表明，主要害虫可在核桃园内完成其生活史，并在落果内越冬，每年可发生4代。本研究结果为防治华北核桃果实主要害虫黄斑虫提供了理论依据。

Primary Biological Characteristics of an Emerging Major Boring Pest, Conogethes punctiferalis (Guenée) (Lepidoptera: Crambidae), on Juglans regia (Juglandales: Juglandaceae) in Taihang Mountains

ABSTRACT: Conogethes punctiferalis (Guenée) (yellow peach moth, YPM) and Atrijuglans hetaohei (Yang) (walnut lift moth, WLM), both boring insects of walnut (Juglans regia), exhibit a competitive relationship due to occupying the same ecological niche. However, the effects of climate change, agricultural management, and irrational pesticide use on the damage caused by these insects remains unknown. Long-term field monitoring in this study revealed that populations of YPM have surpassed those of WLM on walnut since 2018, indicating that YPM, previously considered a minor pest, is now becoming a major pest. Furthermore, field survey results showed that the primary pest can complete its life history in the walnut orchard and overwinter inside fallen fruit, allowing four generations every year. Our results provide a theoretical basis for controlling YPM, currently a major pest of walnut fruit in North China.

期刊介绍： Contributions are accepted on any of the aspects of systematics and taxonomy of insects. This includes: taxonomic revisions, phylogenetics, biogeography and faunistics, and descriptive morphology of insects. Taxonomic papers describing single species are acceptable if such a study is sufficiently justified, however, comprehensive studies that provide a comparative, integrated study of insect systematics and taxonomy will get priority.
