Shoot phloems from eight poplar species were soaked in thesolotions of petroleum ether or methanol, and the effects of their extracts on the activity of carboxylesterase of the larvae of Anoplophora glabripennis were tested. The results showed that the influence of the petroleum ether extract from Populus alba var. pyramidalis on the activity of carboxylesterase was significantly different with that of the extracts from P. canadensis. For methanol extracts, significant differences were found either between P.alba var. pyramidalis and P.tomentosa, P.canadensis cv.“shanhaiguanensis”, P.×euraericana cv.“I-214” and P.×beijingensis or between poplar J-2 together with P.canadensis and P.canadensis cv.“shanhaiguanensis”,P.×euraericana cv.“I-214” and P.×beijingenis.
