Abstract

The possibility of protecting susceptible maize variety from Sitophilus zeamais infestation with powder of known highly resistant maize variety for economic benefits was investigated in a bioassay that lasted for 34 days. The parameters assessed were weevil mortality, number of live weevil, grain damage, grain weight loss, weight of grain powder and oviposition rate. Relative to unprotected stored maize, the performance of the test powder was established after a rating scale developed. Amongst powder concentrations tried 2.0% and 2.50% (w/w) protected the susceptible maize insignificantly against S. zeamais infestation and damage.
