Abstarct: Rhynchites auratus is a Palearctic pest that has distributed in Iran and that is most important pests in orchards. According to lack of information on different Iranian populations of this weevil, in this project five populations in the vicinity of three cities: Bastam, Mojen, Gorgan, Karaj, Quzvin and Mashhad have been selected for geometric morphometric study. Geometric Morphometric were used as a powerful instrument for quantitative statistical shape analysis of three structures; pronotum, elytra and rostrum. Univariate analysis for metric characters and multivariate analysis (multivariate of variance analysis, principle component analysis and discriminant analysis) in geometric morphometric and classical morphology were used. The geometric morphometric approach showed significant differences in the mainly shape of pronotum and also in the shape of the elytra and rostrum. The results of this study indicate separation of Golestan population from other populations. This separation is probably caused by environmental and ecological conditions on different populations.
