Study of geographic variation of Bacterocera oleae (Rossi) (Dip.: Tephritidae) using geometric morphometric analysis, in Guilan province

The olive fly، Bactrocera oleae (Rossi) (Diptera: Tephritidae)، is a serious insect pest of olive crops in many parts of the world. There is no study on population structure of this insect In Iran. In the current research، to investigate morphological variations، geographic populations of olive fly، were collected from five localities in Guilan province. Fourteen landmarks were selected on wing and the shapes were compared among populations using geometric morphometric method. Multivariate analysis of variance and Discriminant Function Analysis were performed on partial warps. The relationship between geographic populations was investigated through UPGMA algorithms. The geometric morphometric analysis showed significant variations in the wing shape and size، among geographic populations.
