摘    要:云斑白条天牛是我国重要林业害虫,在黄河三角洲地区对白蜡树造成严重危害。利用地统计学方法,通过调查城市行道绿化林、庭院绿化林、公路林和片林4种不同林分类型的白蜡树林地,以产卵刻槽、排粪孔和羽化孔为调查指标,对危害白蜡云斑白条天牛种群卵、幼虫、成虫(蛹)的空间格局进行了研究。结果表明:除片林样点成虫(蛹)的半变异函数模型为指数模型外,危害白蜡云斑白条天牛种群卵、幼虫、成虫(蛹)在不同林分类型下的半变异函数模型均为球形模型,其指明空间分布均为聚集分布,种群的聚集分布习性与林分类型相关性不强。但不同林分类型云斑白条天牛种群的空间相关性地统计学参数存在差异,片林调查样点的卵、幼虫和成虫(蛹)的变程a、块金值C0和基台值C0+C均小于其他3种林分类型的统计值,片林样点成虫(蛹)的半变异函数模型不同于其他林分类型为指数模型。

关 键 词:云斑白条天牛  空间分布  地统计学  白蜡树

Abstract:Batocera lineolata is an important wood\\borer pest in China, mainly attacking the trunk of ash trees Fraxinus velutina, a predominant forest species in the Yellow River Delta, causing severe damage. In the present study, the spatial distribution patterns of eggs, larvae, and adults or pupae of the B. lineolata population were analyzed using geostatistical methods. The egg niche, frass hole, and emergence hole at four ash tree sample plots, including a city road greening forest, yard greening forest, highway forest, and patch forest, were investigated. The results showed that the semivariogram curve models of eggs, larvae, and adults (pupae) of B. lineolata populations in different types of ash forests were all spherical, except the adults (pupae) in the patch forest plot were exponential, and the spatial distribution patterns were all aggregated. There were no obvious correlations between the aggregated behavior and living habitat of B. lineolata populations. However, the geostatistical parameters of the spatial correlation of B. lineolata populations in different types of ash forests were obviously different. The range (a), nugget (C0), sill (C0+C) of eggs, larvae, and adults (pupae) in the patch forest were lower than those of the other three types of forests. At the same time, the semivariogram model of adults (pupae) at the patch forest was exponential.
Keywords:Batocera lineolata  spatial distribution  geostatistics  ash trees
