Access to a large number of Chinese and foreign literatures, this text summarized the life cycle of aphids including anholocyclic type, heteroecious holocyclic type and antoecious holocyclic type, and the important biological characteristics including alternation of generations, difference of hibernation and polymorphism, it offered the theory basic of comprehensive prevention and control.
通过查阅大量的中外文献,对蚜虫生活周期的不全周期生活史、全周期同寄主生活史和全周期异寄主生活史进行了阐述,归纳出蚜虫生活周期中的世代交替、越冬方式的差异、多型现象几个主要生物学特点,为蚜虫的科学控制提供一定的参考价值。

Using the methods of classical shape size measuring and chromosome analysis, we studied the morphological characters and Karyotype of Cobitis sinensis in Xiangjiang River. We also investigated the evolution line and Karyotype polymorphism of the C . sinensis by the methods of cytological classification and cytocatalytic. Our results suggest that the formation of chromosome polymorphism was concerned with heterologous hybridization and some of C . sinensis may perpetuate in a clonal manner by natural gynogenesis.
本文以湘江流域的中华花鳅为研究对象,运用经典的形态测量观察方法、染色体制片技术对中华花鳅的形态生态特征、染色体组型进行了初步研究:运用细胞分类和进化方法对中华花鳅的核型演化和核型多态现象的形成进行了分析,提出:其核型多态的形成牵涉到鳅科鱼类的异源杂交,某些中华花鳅可能是行雌核发育生殖的。
