摘　　要：为了明确牧草盲蝽[Lygus pratensis(Linnaeus)]成虫、若虫和卵在棉株上的分布及其习性,采用目测法调查棉株不同器官上牧草盲蝽成虫、若虫和卵的数量。研究显示:蕾期、花期、铃期和全生育期,棉株不同器官上的牧草盲蝽成虫和若虫种群密度间的差异均达到了显著水平,成虫密度:叶片>蕾>花>铃;若虫密度:蕾>叶片>铃>花。牧草盲蝽卵在整个棉株上均有分布,43.5%卵分布在上部,同时叶柄和棉铃上卵量最多。以上结果表明牧草盲蝽成虫主要分布在棉株的叶片上,而若虫主要分布在蕾和叶片上。卵主要集中产在棉株上部,叶柄和棉铃上居多。本研究结果对进一步探明牧草盲蝽生物学特性有重要科学意义。The spatial distribution and habits of adults,nymphs,eggs of Lygus pratensis（Linnaeus）on the cotton were investigated by field observation in this study.The results indicated that the population densities of adults and nymphs differed significantly on different organs of cotton,and the ranking for adults density were leaves buds flowers bolls,and the ranking for nymphs density were budsleaves bolls flowers.On cotton plants,43.5% of eggs were laid on the upper part of the plant,and most eggs were laid on leafstalk and boll.The above results indicated that the adults of L.pratensis were mainly distributed on the leaves of cotton,while nymphs mainly on the buds and leaves.Most eggs were laid on the upper part of the plant,most on leafstalk and boll.All these results are helpful for further understanding biological characteristics of L.pratensis.
