During its last molt, it loses its carapace before curling into its pupal form.

在最近一次的蜕皮，它失去了它的甲壳前冰壶纳入其蛹的形式。

The pupae were exposed to 9 krad 60Co-γ rays for two days before emergence.The adults were dissected and many mature sperms could be seen in the male flies.There were no significant difference in the form,number and vigor of sperm between irradiatid and unirradiated male flies,but there were some abnormal ultrastructurail changes in the sperm of irradiated male flies such as the appearence of vacuoles in nutrient cells,disarrangement of sperms,variation of the number of chondriosome derivates,axonemes ction of formation and abnormal cell division of sperm cells.

用9krad辐照羽化前2天的蛹，成虫羽化后解剖观察，雄虫已有大量成熟精子，精子形态、数量和活力与未经辐照处理的雄虫无显著差异，但其超微结构则发生了某些异常变化，如营养细胞出现空泡、精子排列零乱、线粒体衍生体和轴丝增多或减少、构型被破坏、精子细胞分裂异常等。

The content of diglyceride in the ovary and the fat body was lower than in the blood.

卵巢和脂肪体中的甘油二脂含量较低，化蛹初期仅2～4％，化蛹5日以后增加到7％左右，到羽化前一直无多大变化，但是，摘除咽下神经节蚕甘油二脂的含量反而高于对照区。

Triglyceride content in the fat body was as high as 75% at the initial stage of pupation, but decreased gradually with the development of the pupae. Accordingly, triglyceride content in the ovary was only 20% at the beginning and increased to 64% before eclosion, and the content of diglyceride and free fatty acids in the blood also increased significantly. This suggests that fat in the ovary is transported from the fat body through the blood.

在化蛹初期，脂肪体中甘油三脂的含量高达75％左右，随着蛹体发育而逐渐降低；与此同时，卵巢中甘油三脂的含量在化蛹初期仅为20％，到羽化前增加到64％；血液中甘油二脂和游离脂肪酸的含量也有明显增加，说明卵巢中的脂肪是由脂肪体经血液转送而来的。

The variation in diglyceride content of the SG removal group was similar to that of the control, but its relative content was higher.

甘油二脂在血液中的含量最高，正常蚕在化蛹初期为23.6％，化蛹5日后增加到49.22％，羽化前下降为33.8％；摘除咽下神经节蚕甘油二脂含量变化与正常蚕相似，但是其相对含量高于正常蚕。

Sterol content in the ovary of the normal silkworms was highest (about 18% of total lipids) in the early stage of pupation, began to decrease in the middle stage of pupation and dropped to 7% before egg maturation. When SG was removed, its content in the ovary rose significantly, being about 28% of total lipids by eclosion.

固醇在卵巢中的含量以化蛹初期最高，约占总脂质量的18％，化蛹中期开始下降，到卵成熟时减少到7％左右；但是，咽下神经节摘除后卵巢中固醇的含量显著增加，到羽化前约占总脂质量的28％。

In the early stage of pupation the fatty acid content was about 14% in the control and 8% in the SG removal treatment, and decreased greatly starting from the seventh day after pupation.

脂肪体中游离脂肪酸的含量在化蛹初期较低，化蛹5日后开始增加，到羽化前有咽下神经节区为13％，摘除咽下神经节区为18％，后者显著高于前者。

The results were:The main morphological difference were that the color of squama, median fascia, reniform stigma, orbicular stigma, the part between postmedian fascia and subterminal fascial and terminal hair on forewings, hindwings, terminal hair on hindwings, and the color of skin under squama on obdomen were black, and the color of pupa was also black, and the color of hair on dorsal thorax and obdomen were white.

结果表明： JBM和JBW的主要形态区别表现在成虫前翅上鳞片、中横线、肾状纹、环状纹、外横线及亚外缘线之间的部分、前翅缘毛、后翅、后翅缘毛、腹部鳞毛下的皮肤颜色以及蛹体色等发生了黑化，成虫胸背毛颜色以及腹部毛颜色发生"白化"。

Larva broods first, first eat by moth feeds bark, eat by moth enters xylem after Feburary, principle of eat by moth is general up; Mature larva spits a kind of limy material to make room pupate before pupate.

初孵幼虫，先蛀食树皮，2月以后蛀入木质部，蛀道一般向上；成熟幼虫在化蛹前吐出一种石灰质的物质作室化蛹。
