Insects of the suborder Heteroptera are known for their odor, for being pests, or for being disease carriers. To gain better insight into the cytogenetic characteristics of heteropterans, 18 species of terrestrial Heteroptera belonging to eight families were studied. The presence of heteropycnotic corpuscles during prophase I, terminal or interstitial chiasmas, telomeric associations between chromosomes, ring disposals of autosomes during metaphase, and late migrations of the sex chromosomes during anaphase were analyzed. These features showed identical patterns to other species of Heteroptera previously described in the literature. Another studied characteristic was chromosome complements. The male chromosome complements observed were 2n = 12 chromosomes [10A + XY, Galgupha sidae (Amyot & Serville) (Corimelaenidae) and Pachycoris torridus (Scopoli) (Scutelleridae)]; 2n = 13 [10A + 2m + X0, Harmostes serratus (Fabricius), Harmostes apicatus (Stål), Jadera haematoloma (Herrich-Schaeffer), Jadera sanguinolenta (Fabricius), Jadera sp. (Rhopalidae)], and Neomegalotomus parvus (Westwood) (Alydidae); 2n = 13 [12A + X0, Stenocoris furcifera (Westwood) (Alydidae); 2n = 14 [12A + XY, Dictyla monotropidia (Stål) (Tingidae)]; 2n = 19 [18A + X0, Acanonicus hahni (Stål) (Coreidae)]; 2n = 21 [18A + 2m + X0, Acanthocephala sp. (Dallas) (Coreidae)]; 2n = 27 [24A + 2m + X0, Anisoscelis foliacea marginella (Dallas) (Coreidae)]; 2n = 18 [16A + XY, Oncopeltus fasciatus (Dallas) (Lygaeidae)]; 2n = 17 [14A + X1X2Y, Oxycarenus hyalinipennis (Costa) (Lygaeidae)]; 2n = 16 [12A + 2m + XY, Pachybrachius bilobatus (Say) (Lygaeidae)]; 2n = 26 [24A + XY, Atopozelus opsinus (Elkins) (Reduviidae)]; and 2n = 27 [24A + X1X2Y, Doldina carinulata (Stål) (Reduviidae)]. The diversity of the cytogenetic characteristics of Heteroptera was reflected in the 18 studied species. Thus, this study extends the knowledge of these characteristics, such as the variations related to chromosome complements, sex chromosome systems, and meiotic behavior.
半翅目昆虫以其气味、作为害虫或疾病传播者而闻名。为了更好地了解半翅目昆虫的细胞遗传学特征，对隶属于八个科的18种陆生半翅目昆虫进行了研究。分析了减数分裂前期I异固缩小体的存在、末端或中间交叉、染色体间的端粒关联、中期常染色体的环状排列以及后期性染色体的延迟迁移。这些特征与文献中先前描述的其他半翅目物种呈现出相同的模式。另一个研究的特征是染色体组型。观察到的雄性染色体组型为：2n = 12条染色体[10A + XY，加尔古法西idae（Amyot & Serville）（长蝽科）和酷热厚缘蝽（Scopoli）（盾蝽科）]；2n = 13 [10A + 2m + X0，锯齿异翅长蝽（Fabricius）、尖异翅长蝽（Stål）、血红斑蝽（Herrich-Schaeffer）、血红斑蝽（Fabricius）、斑蝽属（Rhopalidae）]，以及小新巨蝽（Westwood）（缘蝽科）；2n = 13 [12A + X0，叉突狭盲蝽（Westwood）（缘蝽科）；2n = 14 [12A + XY，单突网蝽（Stål）（网蝽科）]；2n = 19 [18A + X0，哈尼无刺猎蝽（Stål）（缘蝽科）]；2n = 21 [18A + 2m + X0，棘头蝽属（Dallas）（缘蝽科）]；2n = 27 [24A + 2m + X0，叶边异角缘蝽（Dallas）（缘蝽科）]；2n = 18 [16A + XY，红纹长蝽（Dallas）（长蝽科）]；2n = 17 [14A + X1X2Y，透明翅尖胸蝽（Costa）（长蝽科）]；2n = 16 [12A + 2m + XY，双叶厚臂蝽（Say）（长蝽科）]；2n = 26 [24A + XY，奥氏阿托蝽（Elkins）（猎蝽科）]；以及2n = 27 [24A + X1X2Y，隆线多尔蝽（Stål）（猎蝽科）]。半翅目昆虫细胞遗传学特征的多样性在这18个研究物种中得到了体现。因此，本研究扩展了对这些特征的认识，例如与染色体组型、性染色体系统和减数分裂行为相关的变异。
