The Cimicomorpha is one of the largest and highly diversified infraorders of the Heteroptera. This group is also highly diversified cytogenetically and demonstrates a number of unusual cytogenetic characters such as holokinetic chromosomes; m-chromosomes; multiple sex chromosome systems; post-reduction of sex chromosomes in meiosis; variation in the presence/absence of chiasmata in spermatogenesis; different types of achiasmate meiosis. We present here a review of essential cytogenetic characters of the Cimicomorpha and outline the chief objectives and goals of future investigations in the field.
食蝽次目是异翅亚目中最大且高度多样化的次目之一。该类群在细胞遗传学方面也高度多样化，并表现出许多不寻常的细胞遗传学特征，如全动染色体；m染色体；多性染色体系统；减数分裂中性染色体的后减数；精子发生过程中交叉出现/缺失的变异；不同类型的无交叉减数分裂。我们在此对食蝽次目的基本细胞遗传学特征进行综述，并概述该领域未来研究的主要目标。
