Abstract

Peasant farmers in northern Nigeria indigenously use various plants to protect cereals and legumes against pest damage during storage. We have developed and employed a simple bioassay technique to assess plants for their ability to protect cowpea from damage by weevil during storage. Of the 10 plants screened, Hyptis suaveolens Poit. (Labiatae) and Sphenoclea zeylanica G earth (Sphenocleacea) showed the best protectant effects after 4 months. The details of the bioassay procedure used and the results obtained are reported.
