Abstract:      A morphological index was used to quantify the morphological similarity 9 geographical populations of the gregarious phase of Locusta migratoria tibetensis Chen. The morphological indicators eleytron length(E), femur length(F), maximum width of head(C), and the ratio E/F, F/C, can be used as morphological markers to determine the relationship between geographical populations. The results obtained by two different statistical methods were similar, which suggests this method is an improvement in analyzing relationships between geographical populations of locusts. The 9 geographical populations were divided into three groups; the first including the Bai ba (BB) and Ba mei (BM) populations. The second group included the Pu lan (PL), Zha nang (ZN), Luo xu (LX) populations. The third group included the Ga er (GE), Xiang zi (XZ), Ri tu (RT) and Na ga (NG) populations.
