[Consanguinity of sixteen olethreutid moth species in northeast China based on RAPD-PCR analysis].

With RAPD-PCR technique, the phylogenetic tree of 16 olethreutid moth species in northeast China was constructed, and their consanguinity was analyzed. The results showed that the clustering of 3 Pandemis species,2 Argyrotaenia species and 4 Archips species on this phylogenetic tree was coincident with their morphological taxology, but that of some other species was not. For example, Clepsis rurinana and C. pallidana were not on the same clade, but on the clade with Pandemis cinnamomeana and Ptycholoma imitartor, respectively. Genetic distance could be an index for genus, and 0.7 was the boundary. The species genetic distance from the same genus was less than 0.7, while that from different genus was more than 0.7.
