Abstract

Larch defoliation by Pristiphora laricis has caused great damage in China. Taking Saihanba Mechanical Forestry Farm of Hebei Province between 2007 and 2010 as the study area, the relationship between the Pristiphora laricis infestation and the habitat factors were analyzed after representative needles and environmental factors were collected. PD (the population density per tree), PIIT (percentage of insect-infected trees in one sample plot) and IA (infected area) were identified as dependent variables to measure the degree of infection. The conclusions are as follows: PD and PIIT have significant differences in areas with different species composition; Canopy density and stand density have a negative correlation with PD; Pristiphora laricis will not infect young growth and it has a tendency to spread to high altitude. At last, in order to provide basis for macro prevention and controlling of insect attack, habitat factors which are closely related to the occurrence of insect attack are input into information load GIS model to estimate the damages caused by insect infection.
