金潤植,柳根燮,林鍾聲,李仁銓,孫海龍 慶北大學校 1980 論文集 Vol.30 No.-
In order to find out new starch sources instead of potato starch, we used fourteen food crops, abundance of sugar and starch, which can be find easily in the market. There were summarizes as follows; 1) Sweet-potato powder, red-bean powder, red-bwder, pumpkin powder, fernbrake powder, burdock powder, lotus-root powder, arrow-root powder, and acorn powder were no good for starch of artificial diet, and especially their smell were bad by affected in feeding response on silkworm larva. 2) Small green pea powder was not so good in cocoon quality, but starch of artificial composition for young instar was adaptable owing to be shortened and be uniformed in larval period. 3) Rice powder and barley powder were affected in the same level for larval characters and cocoon quality to compare control. 4) Wheat flour and corn powder were more adaptable for artificial diet, especially were better affected to cocoon quality, but were delayed in larval period. 5) Water content of arrificial food in opening case was changeable a little in one day in natural condition, but was not problem in rearing room. 6) To feeding response for artifical diet, hybrid of recommended silkworm varieties in the present were so good. 7) But, original races were worse than their hybrid in feeding response. 8) In compare with artificial diet-fed and mulberry-fed that was high mortality contained lost larva ratio, was lowered cocoon production, and was lightened cocoon weight and cocoon shell weight. 9) But, it was good for reeling test than mulberry-fed, especially reelability was higher than control.
