Abstract: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. The genotypes were A632 (resistant to MW) and W64A (susceptible)and their associated mutants. 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 W64Agroup. Feeding activity appeared to be higher in the W64A group having the floury-2 and opaque-2 mutants, which have higher than normal lysine and tryptophan in the endosperm. The waxy and amylose extender mutants, which are thought to contain greater than normal amounts of feeding stimulants and deterrents, did not affect feeding activity and oviposition. Endosperm characteristics may have influenced the texture of the pericarp in some cases.
