中文摘要： 白钩小卷蛾Epiblema foenella L.是药用植物青蒿（Artemisia apiacea Hance）的蛀干害虫，通过田间定点定时系统调查，得出该虫在长沙地区田间1年发生3代，以高龄幼虫在寄主残株及根部蛀洞内越冬，世代发育起点温度为12122℃,有效积温为72652日·度。描述了白钩小卷蛾各虫态及各龄幼虫的形态特征及生活习性，提出了有关预测技术及防治措施的建议。
英文摘要：Epiblema foenella L. is a stem borer of Artemisia apiacea Hance. Through a systematic survey at fixed spots and times we determined that E. foenella had three generations per year in Changsha, and overwintered as old instar larvae in the stumps and hollowed out roots of its host. The effective accumulated temperature of a generation for E. foenella is 72652 degreedays and the threshold temperature for development is 12122℃. The morphological characters and habits of the different lifestages and larval instars of E. foenella are described and forecasting techniques and control methods presented.
