Abstract

In leaf disc choice assays and topical application experiments, the neem (Azadirachta indica) limonoids azadirachtin, salannin, deacetylgedunin, gedunin, 17-hydroxyazadiradione and deacetylnimbin were found to be potent antifeedants and growth inhibitors to the cotton bollworm, Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae). Azadirachtin was most potent in both respects. Gross dietary utilisation (efficiency of conversion of ingested food) of H. armigera was also decreased following topical application as well as after treatment in the diet. Growth inhibition in topically treated H. armigera may be primarily attributed to decreased food intake. The antifeedant and growth-inhibitory effects of the neem limonoids are discussed.

Résumé

Au cours des essais sur rondelles de feuilles et des expériences d'application par voie de contact, les limonoïdes d'azadiractine dérivés du nîme (Azadirachta indica): la salannine, la deacétylegédunine, la gédunine, la 17-hydroxyazadiradione et la deacétylenimbine ont montré des pouvoirs anorexigène et inhibiteur de croissance chez le ver rose du cotonnier, Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae). L'azadiractine était puissante dans les deux variantes de traitement. L'utilisation brute de la diète, c'est-à-dire la capacité de transformer les aliments ingérés, a aussi diminué chez H. armigera lors de l'application par voie de contact de même qu'après l'incorporation du produit dans la diète. L'inhibition de la croissance lors de l'application par voie de contact peut être attribuée en premier lieu, à la baisse de la quantité ingérée d'aliments. Les effets anorexigènes et inhibiteurs des limonoïdes de nîme sont discutés.
