Testing the potential of proposed DNA barcoding markers inNezara virudulaandNezara antennatawhen geographic variation and closely related species were considered

摘要

The COI gene as the core of the DNA barcoding system for animals has received significant attention. The observed wide overlap between intraand interspecific sequence variability has led researchers to envisage the primary COI -based method. The sequences of 16S rDNA, COI , and Cyt b genes of Nezara virudula (L.) (Hemiptera: Pentatomidae) from 13 countries and the same sequences of N. antennata Scott were chosen as molecular markers to analyze the intraand interspecific relationships between the closely related species in this study. The results support that Cyt b gene may be a good candidate alongside COI,when the combined factors of geographic variation and closely related species are taken into account.
