摘要
云斑白条天牛对黄河三角洲地区的重要园林绿化树种白蜡树造成严重危害,研究不同林分类型的空间分布,对云斑白条天牛抽样调查和防治具有参考价值。通过调查片林、庭院绿化林、公路行道林、城区行道林和庭院行道林5种不同林分类型白蜡树林地云斑白条天牛的排粪孔、羽化孔和蛀孔的数量,统计分析其空间分布特点。计算聚集度指标、Iwao回归方程和Taylor幂指数方程结果表明,云斑白条天牛危害片林、庭院绿化林、公路行道林、城区行道林和庭院行道林5种林地时的排粪孔、羽化孔和蛀孔均表现为聚集分布,但不同林分类型的聚集度指标参数、Iwao回归方程的α和β值、Taylor幂指数方程lga和b存在一定差异。
Batocera lineolata(Coleoptera: Cerambycidae) is an important woodborer and severely damages ash trees, a valuable tree for garden greening in the Yellow River Delta. Studies on spatial distribution patterns of B. lineolata at different stand type ash trees are important to sample survey and control. In the paper, spatial distribution patterns of B. lineolata at five stand types’ ash tree, such as patch forest, yard greening forest,highway forest, urban road forest and yard road forest, were studied by investigating the number of frass holes,emergence holes and bored holes of B. lineolata on ash trees. By the computing aggregation index, Iwao regression equation, Taylor power index equation, the results showed that the spatial distribution patterns of B.lineolata frass holes, emergence holes and bored holes were aggregated when B. lineolata attacked at patch forest, yard greening forest, highway forest, urban road forest and yard road forest. However, the parameters of the aggregation index, the α and β value of Iwao regression equation, the lga and b value of Taylor power index equation were different.
