摘要
对 38 6个家蚕保存品种进行无桑人工饲料的摄食性调查 ,蚁蚕 48h摄食率平均为 1 74%,最高为83 98%。蚁蚕 48h疏毛率平均为 0 5 7%,最高为 6 6 4 8%。家蚕种质资源的不同品种对无桑人工饲料的摄食性 ,以中系一化为最好 ,多化最差。 48h疏毛率与摄食率呈高度正相关 (r =0 85 9)。不同品种对无桑人工饲料和有桑人工饲料摄食性的相关系数为 0 0 86 9,未达到显著水平。
Feeding on artifical diet without mulberry for 386 silkworm preserved races were investigated.The results were as follows:The average feeding ratio of newly hatched silkworm is 1.74% within 48 hours,and the highest is 83.98%.The average setae dispersion ratio is 0.57% within 48 hours,and the highest is 66.48%.There were postivie correlation between the feeding ratio and the setae dispersion ratio which reach significant level (r=0.859).The feeding on artificial diet without mulberry of Chinese monovoltine races is highest,and the multivioltine races is lowest.There were not significant correlation between the feeding ratio and the setae disperision ratio of newly hatched larvae with artificial diet without mulberry and with mulberry for silkworm(r=0.086 9).
