From on site investigation, 28 species of bark beetles have been found in the Baishilazi Natural Reserve of Liaoning Province. They belong to four subfamilies and fourteen Genera.Most of the species are subordinate to the species of the Europe-Siberian Range. Three species are dominant, Polygraphus sachalinensis,Pityogenes chalcographus, and Ips acuminatus, A few species,such as Sphaerotypes, coimbatorensis and Tomicus piniperda, inhabit heathy trees, while the others inhabit weakened trees, windfalls, snowfalls and the like. The distribution and damage of the species of beetles show evident differences in various types of forest and heights above sea level. The most important method to control and reduce the numbers of these insects is to remove the weakened trees, snowfalls and windfalls from the forest and treat then as soon as possible before spring.
