Genetic diversity of Dendrolimus punctatus over five regions in Zhejiang Province were studied by ISSR-PCR.Thirteen primers were screened on the template of total DNA of the insects and total 74 bands of DNA fragments...Genetic diversity of Dendrolimus punctatus over five regions in Zhejiang Province were studied by ISSR-PCR.Thirteen primers were screened on the template of total DNA of the insects and total 74 bands of DNA fragments were amplified,of which the half(37 bands)was polymorphic.The genetic distance among the sampled populations ranged 0.114 4-0.475 4.The dendrogram was constructed based on their genetic distance using UPGMA method.The results indicated that there was low genetic diversity among the four populations from the main land,while the Dongtou population sampled from Dongtou island showed higher genetic diversity.展开更多
