Population Genetic Differentiation and Structure of Maruca vitrata (Lepidoptera: Crambidae) in India

Maruca vitrata is one of the primary biotic constraints for pigeon pea production in India. The present study assessed genetic variation and population structure M. from diverse agro-ecologies India using mitochondrial cytochrome c oxidase I gene. A low number segregating sites (10), haplotypes (13), nucleotide diversity (0.00136), overall mean distance (0.0013) were observed among populations. negative values neutrality tests unimodal mismatch distribution supported its demographic expansion country. analysis molecular variance (AMOVA) revealed that populations or groups was only 13.91%, geographical did not significantly contribute to differentiation (R2 = 0.0024, p 0.280). clustering also independent location. Overall, our results suggest existence high gene flow
