柑桔始叶螨与柑桔全爪螨染色体制备方法与核型探讨

Abstract

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.

Key words: leaf mite, chromosome preparation, karyotype, holokinetic chromosome, mixoploidy
