| Abstract: | An experimental area of poplar was established in Songyuan of Jilin Province in 1999 for testing the resistance of different
poplar stains toSaperda poplnea. Incidence ofS. poplnea on ten poplar strains were investigated, and the main trophic component of branches of these poplar trees were measured and
analyzed in April 2001. The results showed that there existed significant difference in population size ofS. poplnea on different poplar strains, and the branches of these poplar strains have significant difference in nutrient component and
content of amino acids. The population size of this pest had a significantly positive correlation with dissolvable total sugar
and water content but had no significant correlation with content of total nitrogen and protein nitrogen.
Foundation Item: This paper is part of the subject of integrated control of longicorn of poplar for mainly focusing on pest resistance, which
was supported by Jilin Provincial Forestry Department (96-010).
