平顶山地区重阳木锦斑蛾发生规律及防治措施

Occurrence Patterns and Management Strategies of Histia rhodope Cramer on Bischofia polycarpa in the Pingdingshan Region

摘要: 重阳木(Bischofia polycarpa)在我国长江流域及其以南地区广泛分布，是兼具观赏、生态和经济价值的重要树种。锦斑蛾(Histia rhodope Cramer)是制约其健康生长的主要害虫。其大规模爆发不仅导致树木失去绿化观赏价值，幼虫的虫丝、粪便还污染环境，对市民身心健康造成威胁，破坏了生态系统的稳定性。本研究旨在通过系统调查，明确重阳木锦斑蛾在平顶山地区的发生规律，为制定科学防治策略提供理论依据。深入研究其发生规律与防治措施，对保护重阳木资源、稳定生态系统也具有重要现实意义。

Abstract: Bischofia polycarpa is widely distributed in the Yangtze River Basin and regions to the south in China, and is an important tree species with ornamental, ecological, and economic value. The moth Histia rhodope Cramer is a major pest constraining its healthy growth. Large-scale outbreaks not only result in the loss of the tree’s ornamental and landscaping value, but also lead to environmental contamination by larval silk and frass, posing potential threats to public physical and mental health and undermining ecosystem stability. This study aims to clarify the occurrence patterns of this pest on Bischofia polycarpa in the Pingdingshan region through systematic investigation, thereby providing a theoretical basis for the development of scientific control strategies. An in-depth understanding of its occurrence patterns and management measures is of important practical significance for the protection of Bischofia polycarpa resources and the maintenance of ecosystem stability.
