Abstract: The occurrence of adult Anoplophora glabripennis in the field can be predicted by using bait trees method.There is a close relationship between the population dynamics of A. glabripennis and the poplar species,the tree age and index number of climate integral.The number of eggs deposited on Populus×euramericana cv.‘Luisa Avanzo’is 2.7 times and 14.5 times of P.×eur. cv.‘I 214’ and P. deltoides cv.‘I 69/55’.The egg number on ‘I 69/55’ of three years old trees is 8 times of that on the five years old trees.The surviving rate of early instar larvae before overwintering has a positive relationship with the index number of climate integral in July to September.It is considered primarily that there is a five year occurrence cycle in the population dynamics of A. glabripennis.
