Feeding activity of the maize weevil (Coloeptera: Curculionidae) on two dent corn lines and some of their mutants

Corn genotypes that naturally differ only in their endosperm constitutions because of mutation were used to examine the feeding and oviposition activities of the maize weevil (MW), Sitophilus zeamais Motschulsky. Differences in the amounts of shallow and deep feeding by MW were found to be consistent within a corn genotypic group with genetically identical pericarp tissue, despite quite different endosperm types. Oviposition was more highly correlated with the number of deep feeding sites in the A632 group and with the number of shallow sites in the W64A group.
