| Abstract: | Polychrosis cunninghamiacola is a major pest of Picea crassifolia in Huzhu county, it has one generation a year. The average egg unmbers of female was 24.7, the eggs were placed the base of new shoot in that year of thickleaf spruce, the period of eggs was 6-7d, the larue underwent 6 instals, the development time was 35- 42d. The control effect applying pynethroids was better. |
