  cocoon
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.

Regarding the temperature of cocoon drying, heat supplying temperture was generally used in the past owing to the inadequacy of the thermoscope4: And the temperature of the heated body was usually deficient. In this experiment, we measured the cocoon layers, pupa shells and hearts of the heated bodies in the processes of drying with modern transistor thermoscopes Through several measurements of the inside heat supplying in 1964-1965, 1975, we have got a few data. In general, a formula may be formed...

Regarding the temperature of cocoon drying, heat supplying temperture was generally used in the past owing to the inadequacy of the thermoscope4: And the temperature of the heated body was usually deficient. In this experiment, we measured the cocoon layers, pupa shells and hearts of the heated bodies in the processes of drying with modern transistor thermoscopes Through several measurements of the inside heat supplying in 1964-1965, 1975, we have got a few data. In general, a formula may be formed as: wall temperature >room temperature >pupa temperature > layer temperature. In the past the highest temperature of drying was controlled below 100? but now it may be raised on to 120癟his experiment, in practice indicates the rational ity of the raising of temperature. In add'tion, with the gradual development of the drying degrees, the temperature of the cocoon layer and the pupa body rises. The temperature risiing in the cocoon layer is higner than that in the pupa body. Attention musto be paid to the grasp of the temperature in the later stage, especially to the final temperature.

对于烘茧温度,过去由于测温仪器的局限性,一般用的都是给热温度。至于受热体的温室,基本缺如。本试验应用现代的半导体测温仪器,对受热体蚕茧的茧层和蛹皮、蛹心,行烘茧进程中的温度实测。经1964、1965和1975年的几次测定,于内部予热式烘茧,初步摸索了一些数据,大体为壁温>室温>蛹温>层温的概念。过去烘茧最高温度规定100℃,现在又提可达120℃,这次试测,就从实践上说明了提高温度的合理性。又在烘茧中,随着干燥程度的逐步发展,茧层温度和蛹体温度就比例上升,茧层温度的上升比又大于蛹体,这是掌握后阶段温度特别是最后温度时特别应该注意的。

An experiment was carried out to investigate the effect of economic use of the amount of mulberry leaves supplied to the fifth instar of the silkworm at the early,middle and late stages.Following results were obtained.1.There was a decrease in both the weight of whole cocoon and the weight of cocoon shell when the amount of leaves supplied was reduced to below the standard level,whether at the early,middle or late stage of the fifth instar,though in different degrees.The more the reduction of the supplied leaves,the wider the range of decrease.In general,there was little effect on the percentage of cocoon shell.2.Reducing the amount of leaves supplied at the early stages of fifth instar had less effect on the cocoon quality than at the other stages.Reduction of the amount of leaves both at the early and late stgaes produced larger effect.3.The economic benefit gained by economizing on the amount of mulberry leaves supplied at the fifth instar is discussed.It is suggested that reduction of leaves supplied at the early stage of the fifth instar will result in greater economic gain in terms of cocoon shell production per picul of mulberry leaves and there is much room for investigation as to the current standard set for the amount of mulberry leaves supplied at the fifth instar

为了探索五龄中不同发育时期减少给桑量对产茧质量的影响,以节约用桑。连续三次对五龄蚕分前、中、后三个阶段进行节约用桑试验,结果表明。 1.不论在五龄前期、中期或后期,凡比标准给桑量降低用桑水平或未热蚕上簇者,全茧量和茧层量都有不同程度的下降,而且给桑量减少愈多,全茧量和茧层量的下降幅度也愈大。茧层率一般影响不大。 2.五龄前期减少给桑量对产茧质量的影响比中期和后期小,前、后期均减食者影响较大。 3.对五龄期节约用桑的经济效益进行了讨论。认为龄初减食经济效益较大,从提高担桑茧层量的要求看,对现行五龄用桑标准大有探讨的余地。

Optimum economical amount of mulberry leaves has been studied for raising the fifth instar silkworms incubated from the eggs on each piece of paper,i.e.20,000 silkworms. The experiments of the ration of the feeding weight have been carried out for many times. The results showed that during the 5th instar the relationship of the changes between various feeding weight and main economical properties of the silkworms follows a certain law in designed ranges, There is an evident limit of the "amount" in the changes....

Optimum economical amount of mulberry leaves has been studied for raising the fifth instar silkworms incubated from the eggs on each piece of paper,i.e.20,000 silkworms. The experiments of the ration of the feeding weight have been carried out for many times. The results showed that during the 5th instar the relationship of the changes between various feeding weight and main economical properties of the silkworms follows a certain law in designed ranges, There is an evident limit of the "amount" in the changes. The lower limit is 350kg, and the upper 450kg. When the feeding weight is below the lower limit, although the cocoon production of each 50kg blades lightly increases, the cocoon shell weight of each 50kg blades significantly dicreascs and the period of the fifth instar is markedly prolonged. When the feeding weight goes beyond the upper limit, although the cocoon production of the same amount of silkworms gradually increases, the cocoon production and the cocoon shell weight obviously dicreases and the amount of the leaves in producing cocoon per 0.5kg evidently increases. Usually, the reasonable litnit of the blades for the fifth instar of 20,000 silkmorms is 350-450kg and the optimum economical amount is about 400kg.

为探讨张种五龄用桑最佳经济指标,作者曾先后多次进行了五龄定量给桑试验。结果表明:在设区范围内,五龄不同给桑量与蚕儿主要经济性状之间的变化关系是有一定规律可循的,存在着较为明显的“量”的界限,其下限为700斤设区,其上限为900斤设区,若给桑量低于下限,担桑茧层量却明显降低,同时龄经过也明显延长,若给桑量越过上限,张种产茧虽渐增,而担桑产茧量和担桑茧层量却明显降低,斤茧用叶量也明显增加。张种五龄合理用桑范围,一般在片叶700斤—900斤设区之间,最佳经济指标,一般在片叶800斤左右。
