Extent of genetic differentiation between two sympatric ladybird beetles, Henosepilachna niponica and H. yasutomii, which are thought to be reproductively isolated from each other by their host preferences alone, was assessed using microsatellite markers established in this project. The analyzed data revealed that the genetic variation both within and between species were very low. These results suggest that the speciation of two species would have occurred so recently with short time that there is little genetic differentiation between them, except for a number of genes associated with their host preferences.

使用该项目中建立的微片状标记评估了两种同胞瓢虫甲虫（Henosepilachna niponica和H. yasutomii）之间遗传分化的程度，它们被认为是通过其宿主偏好彼此彼此隔离的。分析的数据表明，物种内部和物种之间的遗传变异都非常低。这些结果表明，最近在短时间内会发生两个物种的物种形成，以至于它们之间几乎没有遗传分化，除了许多与宿主偏好相关的基因。
