摘  要：
两广二号一代杂交种实验室小蚕人工饲料育与桑叶育对比试验表明:全龄发育经过(正反交)延长2 d 21.5 h;24 h后疏毛率正交、反交分别低0.74、1.44个百分点;幼虫生命率、良蛹率、虫蛹生命率正交比对照区分别低7.52、0.87、7.34个百分点,反交比对照区分别低5.24、0.67、5.87个百分点;全茧量、茧层量和200头蚕产茧量正交比对照区分别低0.11 g、0.02 g和49.67 g,反交对照区分别低0.11 g、0.03 g、27.67 g。建议通过人工饲料适应性选育后再在生产上应用。

摘  要：
The comparison experiment on feeding artificial diet and mulberry leaves to the first generation hybrid of Liangguang No.2 in the laboratory showed that: the development of the larval stage was prolonged for 2 d 21.5 h; setae dispersion rate after 24 h was 0.74 and 1.44 percentage points lower in the reciprocal cross respectively; the survival rate of larvae, healthy pupa rate and larval-pupa rate were 7.52, 0.87 and 7.34 percentage points lower than that of the control respectively, and 5.24, 0.67, 5.87 percentage points lower than that of the control in the reciprocal cross respectively; cocoon weight, cocoon shell weight and cocoon yield of 200 silkworm larvae were 0.11 g, 0.02 g and 49.67 g lower than the control in the cross respectively, and 0.11 g, 0.03 g and 27.67 g lower than the control in the reciprocal cross respectively. It was suggested that the adaptive selection on artificial diet should be carried out before used in practical production.
