Abstract:
Objective To characterize the population dynamics and spatial distribution of Aleuroglyphus ovatus in the flour warehouse,so as to provide the basic evidence for improving the sampling guidelines that are essential for effective pest monitor?ing and management. Methods The samples from flour warehouses of four localities were collected,examined and counted for A. ovatus in every month in Wuhu City. The dispersion pattern target,Iwao m*/-x regression analysis and Taylor power method were used for analyzing the spatial distribution pattern of A. ovatus in the flour warehouses. Results The peaks of population dynamics of A. ovatus were discovered in July and September,respectively. The indexes of dispersion were as follows:I>0, CA>0,m*/-x >1. At the same time,the parameters in the equation of Iwao:m*=5.471+1.022-x (r=0.999)and Taylor:lgS2=0.697+1.111 lg-x (r=0.987)showed that the spatial distribution pattern of A. ovatus was assembled. Conclusion The peaks of population dynamics of A. ovatus in the flour warehouse are bimodal pattern ,and the spatial distribution pattern of A. ovatus is assembled.
