| 摘 要： | 本文利用姬姆萨染色空气干燥压片方法,对花蝽科小花蝽属中国2种小花蝽的性细胞核型进行了研究.研究结果表明该2种小花蝽的2倍体均具有24条染色体和X-Y性别机制,但2种间在染色体行为特征方面具有差别,主要表现在细胞减数分裂的晚终变期和中期常染色体以及性染色体的排列形状与位置等方面,该特征可以用于种间的细胞分类. |

| Abstract: | The karyotype of two Chinese species in Orius were studied in male germ cells prepared on air dried slides stained with Giemsa. It is reported that two species have 24 chromosomes in diploid and X Y sex chromosomal mechanism. But the beha vior of chromosomes during meiosis between two species is different. Which show in the arrangment and location of the X chromosome and autosome at the late diakinesis as well as metaphase stage respectively and so on. These characteristics may be used in ta xonomy among species of Orius . |
| Keywords: | Hemiptera Anthocoridae Orius karyotype chromosome |
