Analytic results showed that 18S rRNA of these insects had two conserved domains and the second domain was an even more conserved region. The phylogenetic trees based on the full-length sequence and the second domain fragment of 18S rRNA as well as sequence of coxl from different orders indicated that Lepidoptera and Trichoptera, which belongs to Amphiesmenoptera, had a closer phylogenetic relationship and fewer differences were observed comparing with traditional taxonomic results.展开更多
