| 摘 要： | 通过测定雅氏山蝉(Leptopsalta yamashitai(Esaki and Ishihara),comb.nov.)若虫头壳宽度的方法,对雅氏山蝉若虫龄期划分进行了研究.采用标准地调查法,用频次比较法拟合,初步得出雅氏山蝉若虫共4龄.用若虫龄级与头宽均值回归进行检验,证实了该蝉若虫共4龄. |

| Abstract: | Through measuring the heail shell width of Leptopsalta yamashitai(Esaki and Ishihara),comb.nov.nymphs,this paper discussed the nymph ages divisions,by using the standard site inverstigation and frequency comparing fitting means,preliminary finel that this nymphs have four ages,and then run the regression test of nymph ages and the heail shell width.Finally confirm this nymphs have four ages. |
| Keywords: | Leptopsalta yamashitai(Esaki and Ishihara) comb.nov. nymph age division |
