在二斑叶螨的磷酸葡萄糖异构酶（PGI）位点检测到两个等位基因。为了阐明螨种群的遗传结构的时间变化，我们引入了两个实验室选择的菌株的螨是纯合的PGI等位基因到乙烯基室内草莓。结果表明，螨类最初倾向于在单个叶片上形成繁殖群体，但随着其密度的增加，它们分散在整个植物上。结果，整个种群在遗传上变得同质化。
Two alleles were detected at the phosphoglucoisomerase (PGI) locus of the two-spotted spider mite, Tetranychus urticae KOCH. For clarifying the temporal change in genetic structures of the mite population, we introduced two laboratory-selected strains of the mites which were homozygous for PGI alleles onto vinyl-house strawberries. The results revealed that mites initially tended to form breeding colonies on individual leaflets, but with an increase in their density, they dispersed all over the plants. As a result, the population became genetically homogeneous as a whole.
