Abstract:
Based on the analysis of the data from a preliminary investigation, the comparative method of I-wao method, Caylor method and aggregated index method were used to study the spatial pattern of Tetranychus Fruncatus. The results showed that the distribution of this mite was an aggregate pattern and the mites occur as colonies; Although the upper and southern crowns had higher mean crowding, the index of patchiness M/M were higher in the lower and northern crown.
Key words:
Tetranychus truncatus,
Spatial pattern
