柑桔星天牛(Anoplophora chinensis Forcst)是柑桔的主要蛀干害虫之一,1981年和1986年分别进行了分布型及防治技术的研究,结果表明,在调查的五个果园中星天牛的空间分布型为聚集分布,其聚集;由环境条件所致,用 Taylor 法则模拟,其方程为S~2=2.3714x~(-1.0164)(r~2=0.96);经理论拟合,结果表明五块园星天牛危害的空间分布有四块园属奈曼分布,一块园属负二项分布,与聚集强度测定结果一致。垂直分布主要分布在离地高度为5cm 以内的主干及砧木上,砧木埋在土下的树要比砧木露在土面上的树受害更 Anoplophora chinensis Forcst is one of the major pests of citrus. In 1981 and 1986, the distributional and control technologies were studied respectively. The results showed that in the five orchards investigated, The spatial distribution pattern is aggregated and aggregated. Due to the environmental conditions, the equation is S ~ 2 = 2.3714x ~ (-1.0164) (r ~ 2 = 0.96) using the Taylor rule. The results showed that there were four Naiman distributions in the distribution of the hazard of five Orion octopus, and a park was negative binomial distribution, which was consistent with the result of aggregation intensity determination. Vertical distribution is mainly distributed in the trunk and rootstock within 5cm above the ground, trees buried under the rootstocks are more damaged than trees exposed on the soil surface
