中国野桑蚕人工饲料育研究初报

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℃以及光照条件1~2龄12 L 12 D、3~5龄15 L 9 D的条件下,野桑蚕人工饲料育的2龄起蚕率为31.3%,幼虫期20~48 d,雌、雄蛹体质量分别为0.45、0.25 g,蛹期17~23 d,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。

Report on Chinese Bombyx mandarina Moore Fed on Artificial Diet

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~(rd),4~(th) 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%.
