Also, they kill the hosts in a concealed but safe position after the hosts cocoon or build their pupal cells.
      
The mean weight gain was 84% of the baseline within 6 weeks, the rate of cocoon deposition was 0.8 per week, and the incubation duration was about 3 weeks, which provided for population doubling within 3 months.
      
A nonlinear negative correlation between the number of juveniles in a cocoon and their weight was found (correlation ratio R= 0.86).
      
The narrow-sense heritability, h2, for batch size was 0.35-0.40; for the number of juveniles in a cocoon, 0.35; for juvenile weight, 0.42.
      
The probability of correlated selection response in traits "number of juveniles in a cocoon" and "weight of juveniles" was estimated.

The amount of urea-N remained in adult silkworm was 22-36% of the amount applied during the fifth-instar.Recoveries from feces were 25-33%;about 11% was found in the residural mulberry leaves,and 25-30% was not recovered,probably lost in the form of NO or NO2.More than 60% of the urea-N that was absorbed by the silkworm was transported into silkgland.The amount of urea-N remained in silkgland accounted for 15-25% of the applied level.The amount of urea-N in cocoon or silk could be compared with those in...

The amount of urea-N remained in adult silkworm was 22-36% of the amount applied during the fifth-instar.Recoveries from feces were 25-33%;about 11% was found in the residural mulberry leaves,and 25-30% was not recovered,probably lost in the form of NO or NO2.More than 60% of the urea-N that was absorbed by the silkworm was transported into silkgland.The amount of urea-N remained in silkgland accounted for 15-25% of the applied level.The amount of urea-N in cocoon or silk could be compared with those in silkgland of adult silkworm,indicating that urea-N transported into the silkgland had been transformed to a component of silk fibroin,but the contribution to cocoon and silk fibroin 'was below 1%.It didn't exceed 3% even though the times or the amount of feeding were increased,or the treatment was combined with ure-ase.lt may be concluded that the direct of addition of urea to mulberry silkworm could be negligible.The contribution of urea-N applied on leaves of mulberry tree to output of silkgland,cocoon and silk fibroin also could be negligible.

在五龄期每日1次叶面添食尿素氮,保留在熟蚕体内的尿素氮量为添加量的22—36%,蚕粪中回收为25—33%,剩桑中11%左右,25—30%没有回收到,可能以NO、NO_2等气态形式损失,未能查明。蚕体吸收的尿素氮有60%以上转移到丝腺中,占添加量的15—25%。茧层和丝中的尿素氮量不低于熟蚕丝腺中的量,说明转移到丝腺中的尿素氮已转化为丝素成分,但其贡献低于1%。即使增加添食次数、添食量或结合脲酶处理,也未使尿素氮对丝物质产量的贡献超过3%,所以尿素添食的直接作用不大。五龄期桑蚕对根外追肥标记桑叶的尿素氮的吸收、转移及熟蚕丝腺、茧层和丝中的尿素氮,比同样试验条件下叶面添食的低50%以上。五龄期1次添食的动态试验表明,在添食后一天内,尿素氮除以粪便排出外,还存在着其他损失途径。

The paper reoorts the distribution pattern of a disease-resistant agent in silkworm larva. 3H-labelled agent was added to feed fifth instar Larva. The radioactivities in silk gland, cocoon shell and pupal cells were determined. The results showed that the agent-treated silkwrom had a high disease-resistant agent distribution in silk gland and cocoon shell, but little was left-over in pupal cell. The further study on physiological mechanism and application of the agent will be based on the experiment....

用~3H标记抗病增丝剂,给五龄家蚕添食处理后,通过对熟蚕的绢丝腺、茧层和蛹体中放射性含量测定,表明该剂主要分布在绢丝腺和茧层中,蛹体内几乎没有。

Silk products on the market of China and abroad are rising of tendency. Eight percent of exports of cocoon filament on international market is from China. Planting bush mulberry on sleep slope land more than 25 degrees with deepen levelditches. 650kg of mulberry leares per mu couldbe produced at hilly region of Shaanbei loess plateau, rearing of silkworms with intact leaf of mulberry at 4th~5th instar larva on three-dimensional rearing seat of plastic folding mountage, cocoon crop per case of silkworm eggs could be 30 kg and income 200 yuan with the leaves produced per mu of bush mulberry field. The ratio of investinent and income is one to four point fifty-eight. There are 12 counties in Shaanbei are suitable for eleveloping of sericulture production. One hundred and twenty thousand mu of mulberry which will not share the land with grain and other economic crops. Local governments could tax sericuhure production of nine million and sixty hundred thousand yuan. At the same time, twenty one million and sixty hundred thousand yuan of remittance could be achieved per year for one county.

丝织品在国内外市场呈上升趋势,我国生丝出口占国际市场的80%。陕北黄土丘陵区以水平槽带状灌木化在25。以上退耕陡坡地植桑,亩产桑叶650kg;用塑料折簇进行大蚕立体片叶育,亩桑养蚕1张,产茧30kg,亩桑年获利200元以上,投产比为1:4.58。陕北有12个县可发展蚕桑生产,每县栽桑12万亩,亦不与粮食及其他经济作物争地,地方获税利960万元,为国家年创汇2160万元。
