Abstract

The oak tasar silkworm, Antheraea proylei J., was reared on the foliage of Quercus serrata Thunb., Q. griffithii Hook. fil. and Thoms, and Q. dealbata Hook, fil and Thoms. under controlled indoor conditions to assess the suitability of these plants as feed for the silkworm. Relative growth rate of the silkworm was lowest on Q. dealbata, perhaps due to the relatively low level of crude protein and high level of crude fibre in this species. These results show that Q. dealbata is a nutritionally inferior food plant in comparison with Q. serrata and Q. griffithii.

Résumé

Le ver-à-soie tasar du chêne, Antheraea proylei J. a été élevé sur feuille de Quercus serrata Thunb., Q. griffithii Hook. fil. and Thoms., et Q. dealbata Hook. fil and Thoms. dans des conditions contrôlées de laboratoire en vue d'évaluer leur convenance en tant que nourriture pour le ver-à-soie tasar, Le taux de croissance relatif du ver-à-soie tasar du chêne était le plus bas avec Q. dealbata à cause peut-être de la moindre teneur en protéines foliaires brutes et de plus de fibres brutes. Ces résultats montrent que Q. dealbata est une plante inférieure sur le plan nutritionnel, comparée à Q. serrata et Q. griffithii.
