| 摘 要： | 采用一种新的染色体制备方法，成功地制备和观察了柑桔始叶螨和柑桔全爪螨的中期染色体。柑桔始叶螨的核型n=4、2n=8，柑桔全爪螨的核型n=3、2n=6或n=4、2n=8。C显带与扫描电镜结果显示，柑桔始叶螨与柑桔全爪螨为全着丝粒染色体，并存在混倍性现象。

| Abstract: | A new method had been developed to prepare the chromosomes of Eotetranychus kankitus Ehara and Panonychus citri (McGregor). It was found that the karyotype of Eotetranychus kankitus Ehara is n=4, 2n=8, and that of Panonychus citri is n=3, 2n=6 or n=4, 2n=8. The results of C banding and scanning electromicroscope photographs indicated that chromosomes of these species were holokinetic. Mixoploidy was also discovered in the karyotypes of these mites. |
