Abstract:

This paper reports the relationship between the outbreak of Anoplophora glabripennis (Motsch.) and management level of poplar forests,the selection of laying eggs to the thickness of host and the prediction of adults and larvae occurrence period. The result showed that damaged level of street trees is the most serious,and that of fast growth and high quality forests is the most slightly,the damaged rates of them are 85% and 7% respectively. The most suitable thickness of branch for adults laying eggs is 8~16cm. The emergence peak of adults is from 20 July to 20 August,it is the most suitable period to control adults. The hatching peak of larvae is from 20 August to 20 September,and this is the most appropriate period to control larvae.

Key words: Poplar, Anoplophora glabripennis (Motsch.), Damage degree, Management level, Prediction
