| Abstract: | Orthosia incerta Hufnagl is one of the important pests of tree that has occured in recent years in early spring of Xinjiang. In fields, its larvae caused great damage to kinds of tree, and appeared peak-hour in April last ten-days period. Its adults tend to light and tend to sugar. The investigation of spatial distribution pattern showed that the larvae belonged to aggregated distribution pattern.More part of larvae is distributed at upper part,middle part and outer edge of the tree,attacking leaves.The density of larvae at outer edge of woods is much greater than that at middle part of woods. |
