摘要： Acetylcholinesterase (AChE) is a key enzyme of the insect nerve system. The enzyme is the primary target of organophosphorus and carbamate insecticides. In this study, we compared the amino acid sequences of AChEs from the organisms tested and found that amino sequence of AChEs showed biggish evolution and conservation. The amino acid sequence of AChEs from Bemisia tabaci was obtained and analyzed. Phylogenetic tree was created based on the amino acid sequence of AChEs in which can exhibited the phylogenetic relationship of the organisms tested. Homology modeling was completed and the AChEs structure and key amino acid points from the aphids tested was viewed. This paper also discussed the B. tabaci AChEs structure characteristics and functional sites.
