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 monitoring 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*/x̅ 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*/x̅ > 1. At the same time, the parameters in the equation of Iwao:m*=5.471+1.022 x̅ (r = 0.999) and Taylor: lgS2 = 0.697+1.111 lg x̅ (r = 0.987) showed that the spatial distribution pattern of A. ovatus was assembled.
Conclusions:
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.
