Abstract

Phylogenetic relationships of Acridoidea were examined using mitochondrial cytochrome oxidase subunit sequences (COI, COII and COIII, total 2970bp). Fourteen grasshopper species of thirteen genera from seven families were sequenced to obtain mitochondrial genes data, along with twenty-two grasshopper species were obtained from the GenBank nucle- otide database. The purpose of this study is to infer the phylogenetic relationships among families within Acridoidea and testing the monophyly of Acridoidea and each families of it. Phylogenic trees were reconstructed using Maximum Like- lihood (ML) and Maximum Parsimony (MP) methods with Tettigonioidea and Gryllotalpoidea as outgroups. The putative initiation codon for COI is CCG in thirteen studied species and ATC in Bryodema luctuosum luctuosum. The 2970 bp con- catenated sequences included 1431 conserved sites, 1539 variable sites, and 1216 parsimony-informative sites, the nucle- otide compositions were significantly biased toward A and T (68.8%). The resulted phylogenetic trees supported the
