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.
The spatial pattern of the mixed populations of Myzus persicae and its parasitoid wasp (Stichopus dauricus and Apis mellifera) in different periods was analyzed by using geostatistics method. The results showed that the semi-variogram The best model was spherical, the best model of adult was spherical - exponential, the optimum model of larvae was linear with abutment, and the best model of semi - variogram of mixed population of egg parasitoid was sphere - exponential. The spatial correlations of dormancy bodies, adults of adult imagoes during the eclosion period, the adult eclosion peak, larvae and egg parasitoids were 53.6, 190.6, 154.1, 4.2 and 280.3 m respectively, and the spatial variability was 30.5%, 95.6% and 96.3 %, 14.9% and 95.3%, respectively.The simulation of spatial distribution using ordinary Kriging interpolation method can be used to intuitively analyze the dynamic changes of the mixed populations of Siniperca penensis and its egg parasitoids at different periods from time and space .
