Analysis of the incidence of stem borers in burned forests in Danxinganling Mountains.

Abstract

After the disastrous fire in 1987, stem borers occurred frequently in burned forests in the Daxinganling Mountains, China. A survey in 1988-89 resulted in the discovery of more than 50 species of stem borers in the region, among which Monochamus sutor and Ips subelongatus were the most predominant species. The populations of the 2 species increased rapidly during the 1-2 years after the fire, and tended to decrease later due to obvious lack of food and a rapid increase of their natural enemies.
