STUDIES ON KARYOTYPE AND G-BANDED CHROMOSOMES OF HYPOASPIS LUBRICA
溜下盾螨染色体组型及其G带的研究

This paper first reports the studies on karyotype and G-banding of the chromosome in Hypoaspis lubrica. The results showed that H. lubrica had 7 (male) and 14 (female)chromosomes, and indicated a haplodiploidy sex determination system. H. lubrica did not show any constriction in karyotype analysis. There were 28 to 30 bands in haploid set of full metaphase by G-banding analysis. This paper first provided a useful method, modified air-drying technique, for studing chromosomes of gamasid mite .
