Occurrence and control of rapeseed stem veevil (Ceuthorhynchus asper Roel.) in northwest China

摘要：

Rapeseed stem veevil (Ceuthorrhynchus asper Roel) is the main rapeseed pest in northwest China, and occurs one generation per year with adult overwintering. The life cycle differ in different area and ecological condition or local climate. For example, different planting region of rapeseed and elevation effect its occurence. In the sloping fields facing sun of the same region, rapeseed stem veevil occurred earlier than in plain and shady fields. In winter rapeseed region, its adults have oversummering habit. In spring rapeseed region, most rapeseed stem veevil overwinter directly under cool climate after pupae becoming into adults. Therefore, to understand the development of rapeseed stem veevil is very important for controlling the insect by using chemical and agricultural measures in the critical period.
