Abstract

Tannin extracts of two sorghum, Sorghum bicolor (L.) Moench. cultivars, BKS5 and BTX 623 were assessed for their bioactivity against the rice weevil, Sitophilus oryzae (L.) (Coleoptera: Curculionidae) and the angoumois grain moth, Sitotroga cerealella (Olivier) (Lepidoptera: Gelechiidae), in whole wheat flour pellets, and against the red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae) in whole wheat flour at three treatment levels. The number of adult progeny was reduced and number of days to emergence increased by tannins extracted from both sorghum cultivars at all treatment levels. However, the effects were not significant in all cases. In a short-term (25 days) feeding test using S.oryzae adults, the presence of sorghum tannins from cv. BKS 5 in the pellets significantly reduced feeding by the insects.

Résumé

Des tanins extraits de deux cultivars (BKS 5 et BTX 623) de sorgho, Sorghum bicolor (L.) Moench. ont été évalués pour leur bioactivité contre Sitophilus oryzae (Coleoptera: Curculionidae) et Sitotroga cerealella (Olivier) (Lepidoptera: Gelechiidae), une fois incorporés dans des boulettes de blé entier. Les mêmes extraits furent mélangés à la farine de blé entier pour aussi évaluer leur bioactivité contre Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae). Tous ces essais étaient effectués à trois nivaux de traitement. Il a été constaté que, quelle que soit l'espèce ou le niveau de traitement, les tanins extraits de deux cultivars de sorgho réduisaient le nombre de progénitures chez les adultes et que la durée à leur émegence s'allongeait. Toutefois dans un essai à court terme (25 jours) au cours duquel les adultes de S. oryzae avaient été alimentés aux extraits incorporés dans les boulettes, la présence des tanins extraits du cultivar BKS 5 a significativement réduit le taux d'alimentation chez ces insectes.
