摘要
以叶螨科中五种叶螨的卵为材料进行叶螨染色体的制备与观察.其方法为四个步骤:(1)低温保存,(2)染色,(3)压片和封片,(4)观测.结果表明:朱砂叶螨、截形叶螨、和土耳其斯坦叶螨的染色体数目均为n=3笔 2n=6,但其染色体相对长度存在差异;李始叶螨的染色体数目为n=4和2n=8;杨始叶螨染色体数目为n=5和2n=10.
The method for preparing and observing chromosomes of 5specieses in the Te-tranychidae has been studied.It includes 4 steps:(1)preserving in the low temperature; (2) staining; (3)tapping and mounting; (4)observing and measuring. The results demonstrated that the chromosonenumbers of Tetranychus (Boisdural), T. truncatus Ehara and T. turk-staniUgron et Nikoliki) were 2n=6,n=3. but different in their length ofchronosome: of Eotetranychus pruni(Oudemans) ,2n=8,n=4;of E. opluli(Koch) ,2n=10,n=5.
