Bio-ecological characteristics of Dendrolimus punctatus tehchangensis in Yunnan Province

Abstract: This article researched preliminarily the biological characteristics and relationship between forest factors and occurrence of D .punctatus tehchangensis .The results show that D .punctatus tehchangensis has two generation one year in Yuanmu County and spends its winter by the third and fourth stadia larave .The spatial distribution patterns of larvae and pupae are congregating distribution , and 2 , congregation is caused by the intrinsic behavior of insect ;2 , congregation is caused by the environment .By using the stepwise-regression method , direction of slope , forest structure , crown density , potential of growth are selected out as the four key factors which have affected occurrence of D .punctatus tehchangensis .The characteristics of the pest-resource stand and the stand with pests but without disaster have been summarized .
