【摘要】 本文研究了中国蝽科昆虫──卷蝽 Ｐａｔｅｒｃｕｌｕｓ ｅｌａｔｕｓ（Ｙａｎｇ）的核型并采用核型分析软件对第一次减数分裂终变期的染色体进行了该型分析。结果表明：卷蝽的２ｎ＝１６，具有ＸＹ性别决定机制，具有一对ｍ－染色体，在有些细胞中出现一个超量染色体。更多还原

【Abstract】 The karyotype of a Chinese pentatomid species Paterculus elatus (Yang) was studied in male germ cells prepared on air-dried slides stained with Giemsa. Karyotype analyses using specific software were made and model karyotype chart was presented. P. elatus (Yang) has 16 chromosomes on mitosis metaphase plate and a X-Y sex chromosomal mechanism. The cytogenetic analysis has revealed the presence of a pair of m-chromosomes and a supernumerary chromosome.更多还原
