广西桉树蛀干害虫的风险分析及管理对策研究

Risk analysis and management countermeasures of eucalyptus trunk borers in Guangxi

桉树蛀干害虫在广西有19种,隶属3目9科。为全面掌握各种蛀干害虫的危险程度,为开展综合管理提供科学决策依据,采用多指标综合评价法对蛀干害虫在广西的风险性进行了综合分析。结果表明:削尾材小蠹Xyleborus mutilatus和云斑天牛Batocera horsfieldi存在高度风险,星天牛Anoplophora chinensis、光肩星天牛A.glabripennis、桉蝙蝠蛾Phassus sp.、咖啡豹蠹蛾Zeuzera coffeae、桉干透翅蛾Sesia sp.等5种害虫存在中度风险,对广西桉树潜在威胁性极大。同时,根据分析结果提出了桉树蛀干害虫的管理对策。

There were 19 species of eucalyptus trunk borers belonging to 9 families 3 orders in Guangxi. A comprehensive analysis of risk of trunk borers in Guangxi was made with the multi-index comprehensive evaluation method to provide basis for scientific decision. The results showed the risks of Xyleborus mutilatus Blandford and Batocera horsfieldi（Hope） were severe and the risks of Anoplophora chinensis （Forster） ,A. glabripennis（ Motsch. ）, Phassus sp. , Zeuzera coffeae Nietner and Sesia sp. were moderate, which were potential threat to eucalyptus in Guangxi. At the same time, the management countermeasures against eucalyptus trunk borers were proposed based on the results of analysis.
