Abstract
Hyphandria cunea
is an insect that can damage hundreds of plants in its larval phase and needs to be placed under quarantine at an international level. Its hosts involve 600 plant species, including forest and fruit trees, shrubs, crops, vegetables, weeds and others. In 2006, we surveyed two Fraxinus chinensis
Roxb stands, damaged to different degrees, after the invasion of H. cunea
in the Changping district of the Beijing area. Given our survey of individual trees and investigation of bio-environmental factors, we provide a preliminarily simulation of the growth situation of F. chinensis
stands, damaged by H. cunea
, by using the Forest Vegetation Simulator software (FVS), which is supported by the "948" project from the State Forestry Administration of China. The results will provide a valuable reference in forecasting the effect of H. cunea
and other invasive pests in China on forest ecological values.
