A preliminary study of pre-harvest insect infestation and storability of four Ghanaian maize varieties

Abstract

The extent of field infestation of one local maize variety and three introduced high yielding varieties by Sitophilus spp. and 1he stability of these varieties in storage were determined. Differences in the levels of field infestation of the four varieties by Sitophilus spp. were not significant at the 5 per cent level. However, the local maize variety suffered a significantly lower weight loss in storage than the high yielding varieties.
