Abstract: Anoplophora nobilis Ganglbauer is one of the most important insect pests of poplar in Shannxi, Gansu Provinces and in Ningxia Hui Autonomous Region. The adults show slow action and have some regularity, acting by day and resting at night. There are two acting peaks during a day: one is about 10 a. m. the other 6 p. m. Their main actions are taking food, mating and laying eggs. The adults have weakly flying ability, usually only spread to and fro in the woods with the farthest distance within 1190m. Their action is mainly affected by temperature. Usually they act very well between 16.0℃ and 28.0℃, but the irregulary action can be observed when temperature is above 32.0℃ or below 10.0℃ The adults prefer to oviposit on the trunks with d. b. h. 7—12cm. The oviposition on the trunk rises with the tree age year by year within definite sizes of the trunk or branch. The adults show some specially preference to bite and oviposit on the cultivars of Section Aigeiros and Section Tacamahaca The different degrees in resistance were observed in Section Leuce to that pest. The insect also has definite choice to other tree species grown near villages, canals, road-sides, and buildings, paulownia and heaven tree appear to be more resistant to the pest. The adult mainly uses its antennae and labipalpi and other sense organs to accurately choose treespecies. Populus×dakuanensis has some chemical message matter that attracts the pest to bite and oviposit. Paulownia seems to have some repellency to the insect. The findings provide some theoretical basis for further study and control of this pest, specially for using insect resistant tree species.
