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 .展开更多

It is reported that number of chromosome and system of sex chromosome of haploid chromosome complement of these species is n=11A＋X （Y） in the first meiotic stage. However, the behavior of chromosomes among the species are different distinctly, thus cytotaxonomic character can be adopted to the identification among the three species.展开更多
