In the first chapter, using fragments of COI gene, we studied the phylogenetic relationships among species of five familes of Acridoidea with MP and Bayesian methods. The results were as follows:(1) Species of Acrididae, Gomphoceridae and all the Arcypterinae species of Arcypteridae are monophyletic. Species of Oedipodidae are supported as a monophyleticgroup, Ceracrinae species of Arcypteridae cluter together to make a monophyletic group. Epistaurus aberrans and Xenocatantops humilis is a phylogenetic group, Stenocatantops splendens and Hieroglyphus banian is also a phylogenetic group.
