Abstract: Resistance of 28 clones of poplars to Anoplophora glabripennis(Motsch.) was investigated.These clones of poplars were divided into 3 groups with cluster method.Among them extremely significante difference was showed by variance analysis (p<0.01).P.×euramericana(Dode)CV"Robusta",P.×euramericana (Dode) CV"Sacrau-79" etc.are more resistant to insects,by contrast,P.pyramidalis,P.nigra,and P.×euramericana,CV.I-214,P.×simopyraidalis are less or intermedium resistant respectively. It is suggested that for establishment of poplars plantion,insect resistance clones of poplars should be selected.If poplars with medium resistance are to be planted,attention must be paid to watering and fertilizing to raise their insect resistance.It is also suggested that suitable small amount of insect susceptive clones of poplars be planted in the edge of plantation as luring trees attracking the insects in order to eliminate the pest in large quantities when it occurs.
