Phylogenetic relationship analysis of chitin synthases (CHSs) in different insect species. A phylogenetic tree was constructed using MEGA 5.0 software using the neighbor-joining method with a bootstrap value of 1000. CHSs are from Spodoptera litura (Sl), Spodoptera exigua (Se), Spodoptera frugiperda (Sfr), Helicoverpa armigera (Ha), Manduca sexta (Ms), Cnaphalocrocis medinalis (Cm), Tribolium castaneum (Tc), Apis mellifera (Am), Aedes aegypti (Aa), Culex quinquefasciatus (Cq), Drosophila melanogaster (Dm), Bactrocera dorsalis (Bd), Aphis glycines (Ag), Anopheles quadrimaculatus (Aq), Ostrinia furnacalis (Of), Plutella xylostella (Px), Mamestra brassicae (Mb) and Phthorimaea operculella (Po).
