Infestaciones con una larva de Diatraea saccharalis (F) en dos variedades tropicales de maíz en México

Abstract

Two tropical maize varieties were artificially infested with one or two Diatraea saccharalis (F.) larvae per plant to determine effect and interactions among yield, tunnel length and position, soluble solids in the stalk, and stalk rot. No consistent efect on yield was demonstrated. Tunnel length was more affected by environment than by variety, internode position, or concentration of soluble solids The borer was involved in the stalk rot spread within internodes and the disease-insect interaction was greater in basal than in the apical internodes
