Abstract
Eleven artificial diets with principal base-ingredients as pulses and beans, viz. winged bean, Psophocarpus tetragonolobus; green gram, Vigna radiata (L.) Wilczek; dew gram, Vigna aconitifolia (Jacq.) Marichat; broad bean, Vicia fabia (L.); soybean, Glycine max Merr.; and cluster bean, Cyamopsis tetragonoloba Taub., were formulated either alone or in combination, for the mass rearing of Chilo partellus (Swinhoe). On the basis of important biological parameters having direct bearing on the selection of media for rearing, seven diets were unsuitable. These diets were compounded with either winged bean, soybean grains (dry and water soaked), or broad bean or with different quantities of cluster bean blended with green gram and dew gram as principal base-ingredients. The superiority of the remaining four diets based on (i) kidney bean, (ii) kidney bean + sorghum leaf powder, (iii) green gram + dew gram, and (iv) green gram + dew gram + sorghum leaf powder, was established. The modified green gram + dew gram + sorghum leaf powder-based diet has an added advantage over its original version due to low cost of production of moths and eggs in both the generations. This highlights the formulation of a new modified diet which can be utilized not only as an alternative to the original green gram + dew gram based diet but also can replace it to overcome the phenomenon of inbreeding depression due to continued rearing in the same diet.
Résumé
Onze diètes artificielles dont les ingrédients de base principaux étaient des légumes et des fèves: voire; fève ailée. Psophocarpus tetragonolobus; pois vert, Vigna radiata (L.) Wilczek; mûre des pois, Vigna aconitifolia (Jacq.) Marichat; grosse fève, Vicia fabia (L.); soya, Glycine max Merr.; fèves éparses en grappes, Cyamopsis tetragonoloba Taub., ont été formulés soit seule soit en combinaison pour la cultivation en grande série de Chilo partellus (Swinhoe). A la base d’importants paramètres biologiques ayant conséquence directe sur la sélection des média pour la cultivation, sept diètes étaient inconvenables. Ces diètes composées soit de la fève ailée, des graines de soya (sees et imibée d’eau); de la grosse fève soit de différentes quantités des fèves éparses en grappes mélées avec pois verts et mûre des pois comme ingrédients de base principaux. Ainsi, la supériorité de quatre diètes basée sur (i) haricots, (ii) haricots + poudre á feuilles du surgho, (iii) pois verts + mûre des pois et (iv) pois verts + mûre des pois + poudre á feuilles du sorgho s’était établie. La diète modifiée composée de pois verts + mûre des pois + poudre á feuilles du sorgha a un avantage sur sa version originaire grce au cout faible de revient des mites et des oeufs dans toutes les deux générations. Cela met en lumière la formulation d’une nouvelle diète modifiée qui peut étre utilisée comme une alternative au diète composée de pois vert + mûre des pois aussi bien qu’il peut remplacer cette diète pour triompher sur le phénomène de la dépression d’éducation á cause de la répétition de la cultivation de la méme diète.
