Abstract: The karyotypes and meiotic behavior of chromosomes in six species (Picromerus lewisi Scott, Dolycoris baccarum (L.), Lelia decempunctata Motschulsky, Menida lata Yang, Erthesina fullo (Thunberg) and Nezara viridula (L.)) of Pentatomidae were studied with male germ cells prepared on the slides air-dried and stained with Giemsa. All the 6 species had the typical diploid chromosome number of 14 for the family Pentatomidae and X-Y sex chromosome mechanism. But the behaviors of autosomes and sex-chromosomes during meiosis in the species investigated had characteristics at the species level. It may provide a useful clue in the study of pentatomid taxonomy and phylogenesis.
