The willow worm, Actias selene Hubner, belongs to the Saturinudae. The worms live outdoor on trees—most frequently on willows. However, they are perfectly fit to indoor conditions. On account of their strong vitality, the breeding of the worms presents almost no difficulty. Our preliminary breeding of the worms shows that under ordinary conditions and feeding with willow leaves they grow very well. In a better case it only takes 24 days from their larvas to cocoon. They breed three generations in one year, and their pupas survive in winter. Willow worms are heavier than ordinary domestic silkworms. A well-developed willow worm weighs over 10 grams and is 7-8 cm. in length. With a green colour, its body is scattered with tumors and full of hairs on their tips. The silk of willow worms presents a light-coffee colour and a shining lustre. As compared with that of domestic worms, it is somewhat thicker, while their tensile strength and elongation are nearly similar. Out of one cocoon a silk thread of about 350 meters in length may be obstained. It has the potentiality of being developed into a textile raw-material.

这篇报告是介绍一种野生蚕——柳蚕和柳蚕丝初步试验的情况。柳蚕在上海一带常见,许多地区也有分布。我们为了探求对它的利用,曾把它移放在室内饲养,发现生长良好,饲养方便。从蟻蚕到结茧,快的24天,就能结茧。一年中一般有三个世代,以蛹越冬。蚕身为绿色,体重比家蚕大,成熟的蚕儿有10克多重,身长达7~8公分。身上有瘤状突起,突起顶端长有刚毛。吐丝呈浅咖啡色,具有光泽,强力和延伸与家蚕丝相仿,但比家蚕丝略粗。柳蚕的特点是:生活力强;吃柳树叶(湿叶也无影响);虽系野生,但能在室内饲养;茧子又可以繅出成缕的丝达350公尺,是天然丝的一种资源。因此它可能具有重大的国民经济意义。

The dry weight of fat body and the volume and dry weightof the hemolymph increase during the course of growth in the last larval instar and de-crease after the commencement of spinning.

The changes in the weights and constituents of the fat body and hemolymph of thefemale and male Eri-silkworm (Philosamia cynthia ricini Boisd.) before and after pupa-tion have been studied and their interrelations discussed. The main results of this inves-tigation are as follows: 1. The dry weight of fat body and the volume and dry weightof the hemolymph increase during the course of growth in the last larval instar and de-crease after the commencement of spinning. The values of the above mentioned quan-tities of the female individuals are always higher than those of the male. However, thedry weight of the fat body begins to decrease in the prepupa stage. This fact indicatesthat the decrease of dry weight of the silkworm during spinning has nothing to do withthe fat body. 2. The major carbohydrate component of the larval hemolymph is tre-halose. Before spinning the blood sugar reserve attains the maximal level: 1513.5 mg/100ml in the female and 1405.4 mg/100 ml in the male. During pupation, sugar of lowmolecular weight other than trehalose appears in the hemolymph. Probably this newlyappeared sugar relates to the formation of chitin. The highest content of fatty acid inhemolymph appears before spinning: 351.6 mg/100 ml in the female and 327.3 mg/100 ml in the male. The change in the amount of the fatty acid in hemolymph isparallel with that of the blood sugar; but the content of the former is lower than that ofthe latter. The total nitrogen content in the hemolymph is much higher than carbo-hydrate and lipid: 2720 mg/100 ml in the female and 1840 mg/100 ml in the male. Itdecreases to about half of this value before spinning. This decrease may be correlatedwith the development of silk glands. 3. The major carbohydrate stored in the fat bodyis glycogen. Before spinning it is 20.0% of the dry weight in the female and 19.5% in the male, during the spinning stage part of the glycogen is hydrolyzed, and from theperiod of spinning to pupation about 70% of it is utilized. 4. The lipid content ofthe fat body increases with the growth in the last larval instar. Before spinning itconsists more than half of the dry weight of fat body: 50% in the female and 59% inthe male, but the weight of the total lipid in the former is higher than that in the latter.In the spinning stage, the lipid continues to be synthesized in the fat body. From theend of spinning to pupation about 33% and 30% of the lipid are expended respectivelyin the female and the male. 5. The change of nitrogenous constituents of fat bodydiffers from that of glycogen and lipid. From the 4th larval moult to the beginning ofspinning it decreases to about half of its highest value. After spinning it increases againto one and one half times its value before spinning. The above facts may indicate thatbefore spinning the nitrogenous constituents are chiefly used for the synthesis of silk andafter spinning the newly formed nitrogenous constituents are stored in the fat body. Thisaccumulation may be correlated to the future development of the reproductive system.This investigation has shown that during the metamorphosis of the Eri-silkworm, the fatbody and hemolymph have important functions in the storage, transportation and meta-bolism of nutrient materials and there is a sexual difference in their contents. It in-dicates that the fat body and hemolymph may play an important role in the maintenanceof normal growth, development and reproduction of insect in general.

Three races of silkworm, Bombyx mori L. namely univoltine "Bagdad", bivoitine"J×C" (at high incubating temperature) and nondiapausing multivotine "Vietnam"were used as materials in these studies. The brain was fixed in Susa or Bouin. Afterfixation it was embedded in paraffin wax and sectioned at 5μ. The serial sections werestained with Mallory's triple stain, somewhat modified, and Gomori's chrome alum-hematoxylin philoxine. The former method proved excellent for the purpose of thesestudies. The neurosecretory cells observed in the brain are arranged in four groups, namelymedial, lateral, posterior and sternopleural groups in each half of the brain, in all eightgroups. The two medial groups are close together on each side of the midline on thedorsal and anterior parts of the pars intercerebralis. The two lateral groups are situateddorsally beside the medial groups. The posterior groups are located on the posteriorparts of the pars intercerebralis. The two sternopleural groups which had not been men-tioned by other authors before are located on the ventral and external-lateral parts, nearthe oesophageal commissure of the brain. The medial neursecretory cells of the univoltine race "Bagdad" were classified intofive types, namely A-, B-, C-, D- and E-cell, which could be distinguished by their sizeand staining reactions with Mallory's procedures. A-cell stained purple, measuring38μ to 42μ in major diameter (without containing of the large vacuole), B-cell which isintensely acidophil, stained deep red, measuring 19μ to 24μ, C-cell stained light grayish-blue, measuring 23μ to 29μ, D-cell stained deep-blue, measuring 18μ to 23μ, E-cellstained deep purple, slender in shape, measuring 24μ to 29μ. The number of the neurosecretory cells in the univoltine "Bagdad" is about 36 onthe fourth day of 5th larval stage, about 46 in the beginning of the pupal stage, about 48and 50 on the third day and seventh day of the pupal stage, respectively. The difference between univoltine "Bagdad" and multivoltine "Vietnam" withrespect to the neurosecretory cells of the brain is the absence of the "B-cell" in the parsintercerebralis of the brain in the nondiapausing multivoltine race.

家蚕一化性品种“巴格达”的脑以 Susa液固定,制成5微米的连续切片,用 Mallory三重染色对脑神经分泌细胞进行组织学观察结果,脑神经分泌细胞的分群除过去学者所记载的脑间部中央群及侧群外,还有后群及腹侧群(这是过去所未曾记载过的)。脑间部神经分泌细胞的类型,过去学者认为只有A、B两种细胞,根据我们的初步观察,由于其大小及染色性的不同可分为 A、B、C、D、E五种类型,用 Mallory三重染色(改良法),除染成紫色的大型A细胞及染成深紫红色的B细胞外,还有染成淡蓝灰色的C细胞,染成蓝色的D细胞及染成淡蓝紫色的长型E细胞。无滞育多化性“越南”品种脑间部神经分泌细胞与一化性“巴格达”品种所存在的差异初步观察为“越南”品种脑间部缺乏嗜复红的“B”细胞。
