WebApr 12, 2024 · The COI gene fragment, which was amplified from 577 individuals in 23 different locations across three central winter wheat regions, ranged from 657 to 658 bp ( Table 2 ). Of the 438 individuals of P. major, nine haplotypes (MH1-MH9) were identified with 22 polymorphic nucleotide sites. Webregion. While there is a high amount of gene flow among populations, fine-scale structure exists and is correlated with the social structure of farmers [15, 16]. It appears that maize weevil population structure may follow similar patterns. The fact that the communities are more connected in Oaxaca than in Chiapas may help to
