Abstract
Limonin, deoxylimonin, citrolin, obacunone, harrisonin and acetoxyharrisonin were assayed as potential antifeedants against the African crop pests, Spondoptera exempta, Eldana saccharina and Maruca testulalis. Even at the highest applied concentration, limonin, deoxylimonin, citrolin and acetoxyharrisonin were not active against S. exempta. At high concentrations, obacunone and harrisonin were mildly active in S. exempta assays. Harrisonin and obacunone displayed potent activity against E. saccharina and M. testulalis.
