They originated  \nfrom wild silkworm (Bombyx mandarina), an insect domesticated 6,000  \nyears ago and raised in China. Chinese people raised silkworms in order  \nto yield raw silk, which is the material for silk manufacture, from cocoons.  \nThere is a theory that they ate silkworm pupas.  \nIt is estimated that the relationship between the Japanese people and silk  \nworms was established at least 2,000 years ago considering that it appears  \nin “An Account of the Wa” in the ancient Chinese book Records of Wei.  \n“An Account of the Wa” describes the  \nlifestyle of the Wajin, the Japanese  \npeople of those days, as follows.“They  \nplant Boehmeria nipononivea and raise  \nsilkworms to yield hemp and silk cloth.”  \n\"An Account of the Wa\"  \n(source: Archives and Mausolea Department, Imperial Household Agency)  \n2  \nC o n t e n t s  \n1.

Accordingly, they will immediately die if they are not being raised by people.  \nWhen the mulberry leaves for their feed have been eaten up, silkworms original position keep still until they are resupplied. Even if a silkworm larva is put on a mulberry leaf, it immediately drops down on the ground because it has no ability to cling on it. In addition, silkworms have no way for protecting themselves from natural enemies and no means for fighting them; therefore, they die easily. In this way, silkworms are insects which rely on people.  \nThey require about 50 days to become adult insects after being hatched from eggs . Silkworms are fledged as they become adult insects, but cannot fly because their body weight is too heavy due to selective breeding. At the same time, their mouth parts degenerate and are lost, leading to a lifetime of at most 10 days.  \nLifecycle of silkworms  \n5  \nContribution to the modernization of Japan  \nHatch, 1st Instar  \nJapan and Silkworms 2  \nSilkworms have been raised by the Imperial Family  \nSilkworm-raising by the Imperial Family has a long history but was temporarily interrupted for a while. Against this background, in 1871, Empress Dowager Shoken restored the tradition of silkworm-raising in the Imperial Court. After that time, this tradition was sometimes interrupted due to fire and war. In 1914, the current Momijiyama Sericultural Institute was established within the Imperial Palace and the tradition of silkworm-raising was resumed and has been inherited up to now. Today, silkworm-raising is being practiced in the Institute every year.  \nThe sericultural industry laid the  \nfoundation for the modernization of Japan  \nIn the past, silkworms were seen as an important species of agricultural animal. Raw silk occupied 40 to 70% of export products from Japan from the late 1800s to the late 1920s and 1930s. Japan overtook China and  \nbecame first in the world for raw silk exports, expediting the modernization of Japan. Raw silk produced in Tomioka Silk Mill, which was registered as a World Heritage Site in 2014, won a great reputation as a “top quality product” around the world. Silkworms, called“Okaiko-sama,” have been raised carefully in special rooms by farmers, up to now. Thus, silkworms are precious to the Japanese people.  \n7  \nContinuous research on silkworms for over 100 years  \n2nd Instar  \nKyushu University and silkworms 3  \nKyushu University is raising about 800 species of silkworms for ","cbCaiqiX9EgG98HB","https://ap.wps.com/l/cbCaiqiX9EgG98HB","pdf",5872282,13,"English","# Contents\n## Life cycle of silkworms\n## Japan and Silkworms\n## Kyushu University and silkworms\n## Pedigree of silkworms\n## Silkworms as a bioresource\n## Evolving research on silkworms\n## Silkworm preservation supported by traditional techniques\n## Long-term preservation realized by advanced technology\n## National Bioresource Project “KAICO”\n## KAICO Bioresource Research Facility","[{\"question\":\"Why do silkworms rely on people rather than surviving independently?\",\"answer\":\"They cannot protect themselves from natural enemies, lack the ability to cling to mulberry leaves, and depend on being supplied with feed.
