四点象天牛的发生与综合防治

Occurrence and Integrated Control of Mesosa myops (Dalman)

摘要: 四点象天牛Mesosa myops (Dalman)属鞘翅目，天牛科，别名黄斑眼纹天牛，主要以幼虫蛀食枝干为害。在我法库县域内对林业、果树及绿化产业均有不同程度的危害。该虫具有寄主多样、不易被发现、为害严重、防治困难的特点。在2022~2024年间，本人通过两年多时间进行了多次实地观察和防治实践，归结出了四点象天牛的发生规律和综合防治方法。

Abstract: The four-pointed longhorn beetle (Mesosa myops, Dalman), a species of the family Coccidae within the order Coleoptera, is commonly known as the yellow-spotted longhorn beetle. It primarily damages trees through larval feeding on branches and trunks. In Faku County, it has caused varying degrees of damage to forestry, fruit orchards, and landscaping industries. This pest exhibits characteristics of host diversity, low detection rates, severe infestations, and challenging control methods. From 2022 to 2024, through over two years of field observations and integrated pest management practices, this study systematically identified the occurrence patterns and developed comprehensive control strategies for the four-pointed longhorn beetle.
