Major pests of maize and control measures in Japan.

Abstract

Major pests of maize in Japan include Pseudaletia separata [Mythimna separata], Ostrinia furnacalis, wireworms [Elateridae], Rhopalosiphum maidis, R. padi, pink borer [Sesamia inferens], black cutworm [Agrotis ipsilon], seedcorn maggot [Delia platura], and several species of birds. Among these, M. separata, O. furnacalis, the aphids, the elaterids and some birds are economically the most important pests. An adoption of cultural control methods including use of resistant varieties is advocated, although at present the major pests have to be controlled using pesticides. Further research is needed to develop adequate combinations of cultural and chemical control measures for effective and low cost management of maize pests.
