Abstract:

Abstract: Spatial pattern of Monochamus alternatus Hope adult was investigated by mothods of clump intensity index, regression patterning and zero frequency estimation in Jiujiang. The results measured by clump intensity indexes (I, K, CA＞0; C, Iδ, M＊/ ＞1; M＊＞ ; L/＞ +1 and 0＜λ＜2 ) suggested the spatial pattern of M. alternatus Hope adult belonged to assemble distribution in pine forest and it was caused by environment factor.
