Distribution of Lepidopterous stemborers of maize (Zea mays L.) in ecological zones of Cross River State of Nigeria

Abstract

A survey of the distribution of maize stemborers in the three ecological zones of Cross River State was undertaken between March to December, 1998 and 1999 respectively. Results of the survey revealed higher stemborer populations in the mangrove zone followed by rainforest and derived Savannah zones of Cross River State. The survey also showed that Sesamia calamistis was more abundant than any other stemborers in all the vegetational zones of Cross River State. This was followed by Chilo orichalcociliella, while Busseola fusca (Fuller) was absent.
