Abstract

Cecidophyopsis mites were studied by PCR amplification of parts of their ribosomal DNA, followed by restriction enzyme analysis. Mite specimens on Ribes nigrum (black currant) from six countries gave the same digestion pattern, which was distinct from the pattern for mites found on R. rubrum from Poland and Finland and for R. grossularia from the USA. This suggests that each Ribes species is host to a different mite species: C. ribis, C. selachodon and C. grossulariae, respectively. Two other mite samples from R. alpinum and R. aureum were identical but were distinct from each of the other species.

摘要

通过对其核糖体DNA的部分片段进行PCR扩增，随后进行限制性酶切分析，对刺瘿螨属螨类进行了研究。来自六个国家的黑醋栗（Ribes nigrum）上的螨类标本呈现出相同的酶切图谱，这与在波兰和芬兰的红醋栗（R. rubrum）以及美国的醋栗（R. grossularia）上发现的螨类图谱不同。这表明每种醋栗属植物都寄生着不同的螨类物种，分别为醋栗刺瘿螨（C. ribis）、鲨齿刺瘿螨（C. selachodon）和醋栗刺瘿螨（C. grossulariae）。来自高山茶藨子（R. alpinum）和金黄茶藨子（R. aureum）的另外两个螨类样本是相同的，但与其他每个物种都不同。
