| 摘 要： | 运用地统计学方法对不同时期麦红吸浆虫及其卵寄生蜂混合种群(宽腹姬小蜂和尖腹黑蜂)的空间格局进行了分析.结果表明:麦红吸浆虫休眠体的半变异函数的最优模型为球型,成虫的最优模型为球型-指数型,幼虫最优模型为线性有基台型,卵寄生蜂混合种群半变异函数的最优模型为球型-指数型.麦红吸浆虫休眠体、成虫羽化初期、成虫羽化高峰期、幼虫和卵寄生蜂混合种群的空间相关范围分别为53.6、190.6、154.1、4.2和280.3 m,空间变异强度分别为30.5%、95.6%、96.3%、14.9%和95.3%.采用普通克立格插值法模拟的空间分布模拟图可较好地从时间、空间两个角度直观地分析不同时期麦红吸浆虫及其卵寄生蜂混合种群的动态变化.

| Abstract: | Geostatistis methods were adopted to analyze the spatial pattern of Sitodiplosis mosellana(Diptera: Cecidomyiidae) at its different development periods and of its egg parasitoids mixed population(Tetrastichus sp.and Platygaster error;Hymoneptera: Eulophidae and Platygastridae).The aggregated spatial arrangements for S.mosellana cocoon,adult,and larva and for egg parasitoids mixed population could be well described by spherical model,spherical-exponential model,linear sill model,and spherical-exponential mod... |
