斑单爪鳃金龟成虫在木荷种子园花期的空间格局

Spatial Distribution Pattern of Hoplia aureola Adults in Schima superba seed orchard

  • 摘要: 斑单爪鳃金龟(Hoplia aureola)是木荷(Schima superba)种子园经营过程中新发、聚集性昆虫,为明确其在木荷种子园花期的空间格局,应用二项分布、Poisson分布等7个理论公式对斑单爪鳃金龟成虫的空间格局进行检验,采用丛生指标(I)、聚集度指标(CA)等7个聚集度指标分析斑单爪鳃金龟成虫的空间格局,并采用Iwao回归、Taylor的幂法则、M*-M等模型进行统计分析。结果表明:斑单爪鳃金龟成虫在木荷种子园中的空间格局以Neyman(n)分布为主,呈聚集分布;采用兰星平Lα-M模型计算斑单爪鳃金龟成虫在木荷种子园中的理论抽样数,得出序贯抽样检索表。研究结果有助于明确斑单爪鳃金龟成虫的动态变化情况,为后期建立长期监测体系提供参考。

     

    Abstract: Hoplia aureola is a newly emerged and clustered insects during the management of Schima superba seed orchard,but its harmful effects are still unclear so far.This study examined the spatial patterns of Hoplia aureola adults using seven theoretical formulas,such as the binomial distribution and Poisson distribution.Hoplia aureola adults was analyzed by applying seven aggregation indices such as clustering index(I)and aggregation index(CA).The statistical analysis was carried out by Iwao regression,Taylor's power law and M*-M models.The results show that the spatial pattern of Hoplia aureola adults in Schima superba seed orchard is mainly characterized by a Neyman(n)distribution,primarily showing gather and distribute.The Lan Xingping Lα-M model was used to calculate the theoretical sample size of Hoplia aureola adults in Schima superba seed orchard,and a sequential sampling table was listed,this helps clarify the dynamic changes of Hoplia aureola adults,providing reference for the later establishment of a long-term monitoring system.
