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。

Our previous studies have shown that ubiquitous overexpression of HmgD caused hemocytes proliferation and the formation of melanotic tumors in the Drosophila larvae. To clarify the mechanism of melanotic tumors appearance,we also generated RT-PCR analysis to test the transcriptional changes of PPAE and Spn27A,which encode the key factors in the phenoloxidasecascade pathway from larvae samples of mid-third instar,late-third instar and prior to pupation relative to wild type flies.Our result showed that in the HmgD overexpression mid-third instar larvae,the expression level.of Spn27A was lower than wild type,otherwise the expression level of PPAE was higher than wild type.It suggests that overexpression of HmgD affects the PO cascade pathway.

本研究组前期工作发现，过量表达HmgD引起果蝇幼虫体内血细胞增生，并出现黑色素瘤，为探讨HmgD过量表达导致了血细胞增生即形成黑色素瘤的分子机制，本研究分别提取三龄中期、后期和相对于野生型化蛹前时刻的幼虫的RNA，首先检测了编码酚氧化酶级联反应途径中的两个关键基因PPAE，Spn27A在突变体中的转录发生变化，结果发现，Spn27A在三龄中期的表达量低于野生型，而PPAE的表达高于野生型，表明过量表达HmgD影响了酚氧化酶级联反应途径，低水平的Spn27A不足以抑制PPAE的活性，活化的PPAE催化了PPO的活性，使其转变成有活性的PO，从而促进黑色素的生成，使果蝇体内产生黑色素瘤。

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&。

The SG showed highest FXPRLamide peptides titer in neural organs. Using an antiserum against H. armigera PBAN, PBAN-like immunoreactivity was detected in the SG and TG of Antheraea yamamai by whole-mount immunocytochemistry, and there were three clusters cells in the SG which shows positive PBAN-like immunoreactivity. The titers of FXPRLamide peptides immunoreactivity in the hemolymph kept a steady level. When pupation, the titer increased promptly, but decreased to a low level after early pupal stage.

这证明了天蚕可能存在FXPRLamide家族神经肽中的DH-PBAN基因；天蚕的咽下神经节中FXPRLamide神经肽含量最高，咽下神经节有三簇细胞合成FXPRLamide神经肽，在胸神经节和腹神经节也有明显的阳性细胞；天蚕5龄幼虫的血淋巴中FXPRLamide神经肽含量比较稳定，化蛹前含量升高，蛹期含量降低。
