| Abstract: | This paper reports the morphological characters of adult,larva and pupa for identification between Zeiraphera laricina and Z.grisecana in Saihanba area.Besides,the occurrence patterns of the two pests in this area are also studied.They have one generation one year.Their eggs overwinter in tree bark and matured cone.The larvae damage the trees from the last ten-day period of April to the mid-ten-day period of June and the old larvae become pupae in the litters.The studies show that elevation is a factor affecting their distributions. |
