The average population density of insects in burnt area is 0.54/100 cm and cerambycids are main species, with quickly inroads and great amount of quantity. In the seriously and medially burnt larch and scotch pine stand,the secondary insects inroad more quickly and the damage rate and insect population density are all higher.

Spruce beetle (Monochamus sutor L.) occurs greatly at timber yards and on burned areas after the May 6 Fire in 1987. Results show that damage rate of lumber is 54.07% and the money lost is about 34.29 Yuan (RMB) per cubic meter in the Timber Yard of Xingan Mountains. In this area, the spruce beetle has one regeneration in a year with larva in winter in the xylem. Chrysalis begins during the last ten days of May with maximum at the first ten days of June.
