Abstract:

Chaitophorus populialbae is one of the principal pests on Populus alba L. and Populus tomentosa Carr, in Shanxi province. A study on pteigostium variation was conducted in 1983 on the pest. The processes of pterigostium mergence, displacement and disappearance of Chaitophorus populialbae was described. It was considered that the tendency of decrease in the number of pterigostium was one of the biological characteristics of the pest, and greatly altered with the change of temperature.

Key words: Chaitophorus populialbae, pterigostium, differentiation
