中国野桑蚕人工饲料育研究初报

Report on Chinese Bombyx mandarina Moore Fed on Artificial Diet

为解决野桑蚕作为试验昆虫在室内饲养难的问题，以江苏启东野桑蚕为材料，用家蚕低成本饲料进行了饲育研究。在催青期温度25℃、饲育温度27—25℃以及光照暑件1-2龄12L 12D、3—5龄15L9D的争件下，野桑蚕人工饲料育的2龄起蚕率为31．3％，幼虫期20—48d，雌、雄蛹体质量分别为0．45、0．25g，蛹期17～23d，雌蛾平均产卵266粒，产滞育卵的母蛾占45．0％。研究结果表明，人工饲料育能够使野桑蚕顺利完成世代发育。

In this research, Bombyx mandarina from Qidong, Jiangsu, was used to investigate its growth and development by feeding low-cost artificial diet, and has successfully been bred for two generations. Under the conditions of incubation temperature 25 ℃, rearing temperature 25 -27 ℃, 1^st and 2^nd instar photoperiod 12： 12, 3^nd, 4^6h and 5^th instar photoperiod 15： 9, the results shows that the 2^nd instar newly-molted silkworm rate is 31.3%, the larval stage duration is 20-48 days, the male and female pupa weight are 0.25 g and 0.45 g, respectively, the pupal stage duration is 17 -23 days, average amount of laid eggs per moth is 266, and the rate of moth laying diapause eggs is 45%.
