中文摘要： 【目的】 白眉野草螟Agriphila aeneociliella (Eversmann)是近几年在山东、山西发现严重危害小麦的新害虫，其同属的北美田草螟A. vulgivagella (Clemens)在美国和加拿大危害小麦、黑麦等，它们是否可以对全国小麦主产区构成威胁，需要进行其适生区的研究。【方法】 根据现有分布区的最佳拟合获得预测参数，利用CLIMEX模型获得2种害虫在全国小麦生产区的适生区。【结果】 白眉野草螟和北美田草螟在我国小麦主要产区均具有很高的适生性（EI值>20）。【结论】 对白眉野草螟加强防控防止扩散危害、对北美田草螟加强检疫防止入侵我国，对保护我国小麦安全生产均具有重要意义。
英文摘要：
[Objectives] The insect Agriphila aeneociliella (Eversmann)] is a new pest of wheat crops that has appeared in Shandong and Shanxi Provinces in the past a few years. Another species in the same genus Agriphila Hübner, A. vulgivagella (Clemens) is also a pest of wheat and rye crops in the US and Canada. Their possibly damage areas in China is essential to wheat production. [Methods] Based on actual happens and biological characters, their potential distribution areas in China were analyzed by using of CLIMEX model. [Results] CLIMEX model analysis indicates that the EI values of both species are > 20 in most of China’s main wheat production areas. [Conclusion] It is important to both limit the spread of A. aeneociliella and prevent the introduction of A. vulgivagella through effective quarantine measures.
