为实现桉树油桐尺蛾的有效防控,本文分析了广西国有三门江林场2024年桉树油桐尺蛾的发生特点和现状,并提出了相应防治策略。分析显示,研究区油桐尺蛾1年发生3代,以蛹在表土中越冬,幼虫具暴食性,成虫喜夜间活动、飞翔能力和趋光性均较强。油桐尺蛾在研究区为害面积较大,5月和7月为暴发期,为害较重;为害树龄集中在中林龄和近熟林,且桉树萌芽林较植苗林为害严重。为此,提出以下综合防控措施:设置固定监测点,构建“总场+分场+基地”监测网和实行分类监测等健全监测体系;采用人工挖蛹,喷施苏云金杆菌预防,设置诱虫板和灭虫灯等实施防控;结合延长抚育年限和培育桉树大径材等优化林地经营;开展虫害科普宣传和技术培训等构建联防机制。本文为桉树油桐尺蛾的综合防控提供参考。

To achieve effective prevention and control of Buzura suppressaria on eucalyptus, this paper analyzed the occurrence characteristics and current situation of Buzura suppressaria on eucalyptus in Guangxi State-owned Sanmenjiang Forest Farm in 2024, and put forward corresponding control strategies. The analysis showed that Buzura suppressaria had 3 generations per year in the study area, overwintering as pupae in the surface soil. The larvae were highly voracious, and the adults were active at night with strong flying ability and phototaxis. Buzura suppressaria caused damage over a large area in the study area, May and July were the outbreak periods with severe damage; the damaged tree ages were concentrated in middle-aged forests and near-mature forests, and the damage to eucalyptus sprout forests was more serious than that to seedling-planted forests. In view of this, the following control measures were proposed: improving the monitoring system by setting up fixed monitoring points, constructing a “general farm + branch farm + base” monitoring network and implementing classified monitoring; implementing prevention and control by manually digging pupae, spraying Bacillus thuringiensis for prevention, and setting up insect traps and insecticidal lamps; optimizing forest land management by extending the tending period and cultivating large-diameter eucalyptus timber; and constructing a joint prevention mechanism by carrying out popular science publicity and technical training on insect pests. This paper provides a reference for the comprehensive prevention and control of Buzura suppressaria on eucalyptus.
