| 摘 要： | 采用姬姆萨染色压片法,对花蝽科山地原花蝽性细胞进行了核型研究.结果表明该种单倍染色体组成为n=14A+XY,为无交叉减数分裂,性染色体经历后减数分裂,上述核型特征为阐明臭虫型内不同科的系统发育关系具有重要意义. |
| 关 键 词： | 半翅目 花蝽科 山地原花蝽 核型 系统发育 无交叉减数分裂 后减数分裂 姬姆萨染色压片法 |

| Abstract: | The karyotype of Anthocoris montanus Zheng (Anthocoridae, Heteroptera, Cimicomorpha) is described in detail forthe first time through the use of Giemsa staining and "squashed" slides. The species displays the chromosome complement n =14A + XY, and sex chromosomes undergo post-reductional meiosis. Moreover, male meiosis is achiasmatic in this species. Thisfeature is significant in clarifying phylogenetic relationships among families of the Cimicomorpha for the future. |
| Keywords: | Anthocoridae karyotype achiasmatic meiosis p ost-reduction |
