Species identification of mosquitoes is challenging yet necessary to select appropriate control methods for each species. In this study, we have analyzed the different wing components for identification to find the optimal outline for <em>Aedes</em> mosquito analysis by an outline-based GM approach. Two internal and external outlines of the wing were considered for <em>Aedes</em> species identification in this study. A total of 90 <em>Aedes</em> wings were analysed, divided into 30 wings per species (<em>Ae. aegypti, Ae. albopictus</em>, and <em>Ae. scutellaris</em>). The results showed that the mean size of <em>Ae. albopictus</em> had the largest wings, followed by <em>Ae. Aegypti,</em> and <em>Ae. scutellaris</em>, respectively, in all the internal and external outlines. While, the shape analysis in the three outlines were expressed by the factor map, the statistical difference and cross-validated classification scores indicated the ability of the outline-based GM approach to distinguish species of <em>Aedes</em> mosquitoes. The external outline has a relatively good range of cross-validated classification scores compared to the other internal outlines. The results of this research reveal the suitability of this external outline to identify species of <em>Aedes</em> vectors in Thailand.</p>}, number={1}, journal={Journal of Entomological and Acarological Research}, author={Chaiphongpachara, T. and Laojun, S.}, year={2019}, month={Aug.} }
