- Abstract
Mass attack by the pine shoot beetle, Tomicus piniperda (L.), on the trunks of living trees was a main cause of Yunnan pine forest damages in Kunming, China, from the 1970s to 1990s. The present study, based on analysis of egg galleries, proposed that mass attack was initiated with the establishment of a few primary invaders and intensified as the partners followed. The attacking beetles increased with time in the first part of a mass attack. Dispersion of the population on the trunk surface was started from the positions the primary invaders colonized and spread to nearby locations. The population was mainly distributed in the upper and middle of trunk, but revealed the highest density in the middle.
