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:...

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。

This paper described that fivespecise of intestinal pathogenic bacteria of Chinese oak silkworm, including the pathogenic bacteriumof-Empty-Gut disease of A. Pernyi, Streptococcus pernyi, Could induced thediapausing pupae of A. Pernyi to produce antibacterial substances in the hemolymph. The antibacterial substances of A. Pernyi pupae induced by the intestinal pathogenic bacteria had been compared with that by Escherichia coli K-12 D31. It was found that the antibacterial activity induced by the intestinal pathogenic bacteria was much higher than that by E. coli. and the period of antibacterial activity lasted in the hemolymph of the pupae induced by the pathogenic bacteria was also much longer than that induced by E. coli. The polyacrylamide gel eletrophoresis showed that the antibacterial substances induced by injecting with two species of the intestinal pathogenic bacteria had higher ratios in P5, P9a and p9b, and it was also observed that the different components of antibacterial substances was not appearing and disappearing at the same time in the hemolymph of the pupae after it was induced.

It has been confined recently that the incorporation of heterogeno-us DNA into a receptor may induce hereditary variations in higher animals. In the present experiment, when the pupae of Antheraea per-nyi are injected with the DNA prepared from pupae of Dictyoploa japonica, a new variant possessing specific features is obtained. The colour and size of eggs, larvae, pupae and mothes, as well as some biochemical specificities such as polyacrylamide gel electrophoritci pattern of the serum esterase zymograms and the amino acid content of the variant are between the donor and the receptor. The aberration rate found in both characteristics mentioned above are 5.59% and 8.6% respectively based on the observations through six yields and eleven generations.Cross and testcross experiments of the variant with untreated Antheraea pernyi mothes show the typical Mendel separation ratio in the colour of newly hatched larva which implied that this variant is homozygous so that it can be bred true in this recessive aberration. Present work may provide an evidence for the theory in which it is suggested that hetergenous DNA can be integrated into eucaryotic genoma and can be expressed. It also showes that the method in which the heritable variation produced by treatment with heterogenous DNA is probably a good method to be used for the improvement of vatiety.

近年来证实了高等动物体内异源DNA能整合到受体基因组引起动物发生遗传变异.根据这个论点,我们把生活力强的野生蚕种桑蚕DNA注射到柞蚕蛹体内,获得了具有特异性状的变异蚕和变异卵,其变异率分别达到5.59%和8.6%.经6年11代,观察变异蚕的卵、幼虫、蛹及蛾的颜色、大小都介于供体和受体之间,其血清酯酶、同功酶谱带和氨基酸含量等生化指标也介于二者之间,经杂交及侧交试验证明此变异蚕蚁蚕体色为隐性纯合型,能够稳定遗传,而且符合孟德尔的杂交分离规律.我们的实验结果进一步充实了真核细胞基因组能够整合异源DNA,且能予以表达的理论.表明异源DNA诱导遗传变异可能是选育优良品种的一个好方法.
