| Abstract: | The present paper deals with spatial patterns of adult of ladybird beetle, Coccinella septcmpunctata L. on oriental arborvitae in mountainous district in Hobei province. The spatial patterns of adults of the beetle were of an aggregated distribution. Of which the basic element is the colony. The distribution of basic elements were of uniform. The beetle adults occur as loose colonies, which mean size=2m~2, Distribution of the colonies is aggregated and intracolony distribution is random. |
