Abstract

The efficacy of natural embelin isolated from berries of Embelia ribes Burm. against Tribolium Castaneum Herbst is discussed. Embelin mixed with wheat samples at concentrations of 0.1875% and above exhibited high efficacy by bringing about adult mortality even after 8 months of storage. Productivity (progeny/adult-day) of the test insect was also reduced significantly in treatments as compared to controls at different intervals of storage. After 8 months of storage, significant reduction in F1 progeny at the lowest concentration was mainly due to larvicidal action of embelin. In the present study, embelin did not exhibit any chemosterilant action or contact toxicity to adult beetles. Germination of wheat treated with embelin even at the highest concentration of 0.750% was not impaired to any significant extent.

Résumé

On a discuté l’efficacité de l’embelin naturel isolé des baies d’ Embelia ribes Burm., contre le ténébrion, ou l’escarbot rouge de la farine. Une concentration de 0,1875% de l’embelin dans le blé a produit la mortalité chez les insectes adults, même après 8 mois d’entreposage. La productivité (c’est-à-dire, le nombre de descendants/adult-jour) de l’insecte dans les lots traités avec l’embelin était réduite significativement, pendant toute la période d’entreposage. Le nombre de descendants F1, après 8 mois d’ entreposage, était réduite significativement, même à la concentration minimale (0,094%) de l’embelin; ce qui implique que l’embelin est, principalement, un larvicide. L’embelin n’ a montré, sur les escarbots adults, aucune action chémosterilisanteou de la toxicité du contact. La germination du blé n’était point affaiblie, même à une concentration de 0,750% de l’embelin.
