摘    要:运用 7种聚集度指标 ,测得杨小舟蛾第 1,3代卵块在杨树林内的空间分布型属均匀分布 ;第 1代幼虫属均匀分布 ,第 3,4 ,6代幼虫属聚集分布。通过方差分析 ,F检验和SSR测验表明 ,杨小舟蛾第 1,3,4 ,6代幼虫在树冠东、南、西、北 4方位间虫口数量差异均不显著 ;第 1,3,6代幼虫在树冠上、中、下 3层间虫口数量差异均不显著 ,第 4代幼虫在树冠上、中、下 3层虫口数量差异为 :上层与下层及上层与中层间差异均极显著 ,中层与下层间差异显著

关 键 词:杨小舟蛾  空间分布型  聚集度指标

Abstract:The space distribution model of egg cakes produced by the first and third generation larva of Micromelalopha troglodytaa is tested to be homogenous distribution by using seven kinds of polymerizing degree index.The space distribution model for the first generation larva is homogenous distribution,but that the third,forth and sixth generation larva of Micromelalopha troglodyta is polymerizing distribution.The difference of insect quantity in every direction of crown is not notable for the first fourth and sixth generation larva of it neither is that in the upper,middle And lower of crown for the first,third and sixth generation larva of it But the different of insect quantity is very notable in the upper middle.And lower of crown for the fourth generation larva.
Keywords:Micromelalopha troglodyta (Graeser)  Space distribution model  Polymerizing degree index
