摘　　要：在室外条件下调查了野燕麦、节节麦、雀麦、鹅观草、野大麦和小麦等小麦吸浆虫几种主要禾本科寄主的生物生态学特性。结果表明,在生长前期和后期,这几种寄主的生物生态学特征都有一定的差别,从根、茎、叶等组织器官上可以将它们区分开。同时对其株高、叶长、叶宽、穗长、分蘖、单穗结籽数等特征进行了调查,结果均表现出明显的差异。At outdoor, we investigated the biological and ecological characteristics of the host plants of wheat midge, including Arena fatua L. ,Bromus Cartharticus Vagl,Roegneria kamoji Ohwi,Hordeum brevisubularurn （Trinius） L. and Zhengmai 9023. The results showed that the ecological characteristics at their early stage and late stage growth had significant differences. The hosts were differentiated based on roots, stems and leaves. Meanwhile, the height, leaf length, leaf width, spike length, tillering number and reproduction number were studied in details and showed significant differences.
