Abstract
Limonin, deoxylimonin, citrolin, obacunone, harrisonin and acetoxyharrisonin were assayed as potential antifeedanfe against the African crop pests, Spodoptera exempta, Eldana saccharina and Manica testulalis. Even at the highest applied concentration, limonin, deoxylimonin, citrolin and acetoxyharrison 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.RésuméLa limonine, la deoxylimonine, le citroline, l'obacunone, l'harrisonine et l'acetoxyharrisonine étaient tous essayés comme anti-nourrissants potentiels contre les pestes des plantes Africains sur la liste suivante: Spodoptera exempta, Eldana saccharina et Maruca testulalis. Mème avec le plus grand niveau de concentration appliqué, la limonine, la deoxylimonine, le citrolinine et l'acetoxyharrisone n'étaient pas actives contre S. exempta. Avec beaucoup de concentrations de liquide, l'obacunone et l'harrisonine ont montré très peu de reponse dans l'analyse de S. exempta. L'harrisonine et l'obacunone ont montré l'activité potentielle contre E. saccharina et M. testulalis.
