Abstract:

It was different significantly that the activity of the carboxylesterase of the Anoplophora glabripennis feeding different poplars, with the same negative correlation trend as the resistant sequence of the six poplars species. The activity of the carboxylesterase in Populus tomentosa, a resistant poplar, decreased gradually as the time of eating increased. But kinetics studies showed that this change is mainly because of the change of CarE molecular before the ten-days of eating. Quantitative differences might gradually replace the role within the later days. To P. canadensis, a sensitive poplar, the activity of the carboxylesterase increased gradually with the increase of eating time, and the quantitative differences play a key role in the change.

Key words: poplar, Anoplophora glabripennis, carboxylesterase
