Abstract:
Objective To understand the natural population dynamics and spatial distribution of Tyrophagus putrescentiae in storage flour,so as to provide an evidence for its prevention and control. Methods The samples from five sampling points in Wuhu City were collected monthly from January to December,2013,and examined and counted for T. putrescentiae. The disper-sion pattern target,Iwao's m*--x regression analysis and Taylor's lgS2-lg-x regression analysis were used for analyzing the spa-tial distribution pattern of T. putrescentiae in the storage flour. Results The peaks of population dynamics of T. putrescentiae were discovered in July and September. The indexes of dispersion were as follows:I>0,CA>0,m*/-x >1;and the linear re-gression equation of Iwao:m*=3.7403+1.0175-x (r=0.9958)and Taylor:lgS2=0.5004+1.1349 lg-x (r=0.8328) showed that the spatial distribution pattern of T. putrescentiae in the storage flour was assembled. Conclusion The peak of pop-ulation dynamics of T. putrescentiae in the storage flour in Wuhu City is a double peak type,and the spatial distribution pattern of T. putrescentiae is assembled.
