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

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(C_A).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 L_α-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.
