Resumen:
Mexico is the center of maize Zea mays L. domestication with a large
diversity of landrace genotypes that are of great economic, cultural and
social importance. Landrace maize genotypes are mainly cultivated by
smallholder farmers for local and specialized markets of culinary
dishes, However, all maize genotypes are subject to insect herbivory
among which the Fall Armyworm (Spodoptera frugiperda Smith and the White
grub larvae (Phyllophaga vetula Horn cause serious yield losses, by
feeding on leaves and roots, respectively. Here we investigated the
response of landrace and hybrid maize genotypes to herbivory from foliar
(S. frugiperda) and root feeding (P. vetula) insects with five maize
landrace and five hybrid maize genotypes. The main results showed that
landrace maize genotypes suffered from a higher level of herbivory by S.
frugiperda than hybrid maize genotypes. For root herbivory, no clear
differences between landrace and hybrid maize were observed and overall,
only one out of the five maize genotypes for each type of maize were
negatively affected from the presence of P. vetula. In conclusion, maize
genotypes respond differently to root and foliar herbivory, which should
be considered when developing pest management strategies in maize
agroecosystems.
