A direct relationship was observed between corn (maize) plant density and girdling of infested stalks by Diatraea grandiosella Dyar. Increases in plant densities caused increases in the incidence of girdling of infested plants. Stalk soluble solids increased with plant density but no cause and effect relationship was inferred between soluble solid content and girdling. Stalk moisture content did not vary significantly among plant populations. Plant densities did not affect rates of infestation by 2nd generation southwestern corn borers.
