Abstract

A field experiment was conducted at the Experimental Station of Campos, Rio de Janeiro, Brazil, with the objective of determining the incidence of Diatraea spp. (LEP. - Pyralidae) in sorghum (Sorghum bicolor (L.) Moench). The genotypes CMS XS 623, BR 501 and BR 505, were utilized in various planting dates (September, October and November, 1983). There were no statistical difference among the studied genotypes in relation to the incidence of Diatraea spp. However the genotype BR 505 showed the tendency of resistance to the borer infestation. The first planting date was significantly the one who presented the least infestation compared to the others.
