| 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. |
