It extends through most of the body, and connects to a short sclerotised intestine and anus in the hind part of the abdomen. In ancient competition with cotton, linen, wool fiber, silk was always the winner. It is the hungry silkworms that wander around. Silk production from the silk worm . It is an economically important insect, being a primary producer of silk. The major objectives are improving fecundity (the egg-laying capacity of a breed), the health of larvae, quantity of cocoon and silk production, and disease resistance. Silkworm Moth Reproduction After mating, the female silkworm moth lays her tiny eggs on mulberry leaves. Natural polymers are receiving more and more attention due to their abundant sources and sustainability. Finally, the evil god summons his fellow thunder and rain gods to attack and burn away her clothes, forcing her to hide in a cave. [19], Silkworms have also been used for the identification of novel virulence factors of pathogenic microorganisms. These enzymes are destructive to the silk and can cause the silk fibers to break down from over a mile in length to segments of random length, which seriously reduces the value of the silk threads, although these damaged silk cocoons are still used as "stuffing" available in China and elsewhere for doonas, jackets, etc. Human beings can harvest the cocoons and extract the threads to make silk fabric. SILK MERCHANTS: With the help of inserted spider genes, these newly hatched transgenic silkworms can spin silk that is closer to that spun by arachnids. Silkworms are native to northern China. [18], There are characteristics that are particularly important for the terrestrial lifestyle of arachnids, such as internal respiratory surfaces in the form of tracheae, or modification of the book gill into a book lung, an internal series of vascular lamellae used for gas exchange with the air. That is to, The Maritime Silk Road existed before the Land Silk Road, and the Maritime Silk Road had routes from the East China Sea and the South China Sea. And one species of spider is mostly herbivorous. It ranges from northern India to northern China, Korea, and Japan. Carbohydrates also play an important role in aspects of body function and cell construction. Bombyx mori, the domestic silk moth, is an insect from the moth family Bombycidae. She lays eggs on the leaves of mulberry trees. They are covered with little black hairs. For many years silk was a primary commodity traded by China with the West along the Silk Road, and the silk production process was a carefully guarded secret for thousands of years. For Giant silk moth, see, The International Silkworm Genome Consortium (2008) The genome of a lepidopteran model insect, the silkworm. Slit sense organs are believed to be involved in proprioception, and possibly also hearing. is silkworm an arachnid Classification of Silk Cocoons Saturday, 24 July 2021by Elizabeth According to the requirements of the silk-making process, the process of selecting and classifying the raw cocoons. The cocoon may be white to yellow in color. Dab at the sweat stain. In general, as long as you turn to a few basic household ingredients, you can, Pen ink stains can happen in the blink of an eye. - BBC Wildlife Magazine, Transcriptomic Analysis of Pseudoscorpion Venom Reveals a Unique Cocktail Dominated by Enzymes and Protease Inhibitors, From father to son: transgenerational effect of tetracycline on sperm viability, The Enzymatic Core of Scorpion Venoms - PMC - NCBI, Characterisation of protein families in spider digestive fluids and their role in extra-oral digestion, Molecular basis of anticoagulant and anticomplement activity of the tick salivary protein Salp14 and its homologs, Tick Paralysis - StatPearls - NCBI Bookshelf, Sexual dimorphism in the Arachnid orders - PMC - NCBI - NIH, "Sexual dimorphism in the Arachnid orders", Wilderness Medicine: Expert Consult Premium Edition, "A Phylogenomic Approach to Resolve the Arthropod Tree of Life", "A congruent solution to arthropod phylogeny: phylogenomics, microRNAs and morphology support monophyletic Mandibulata", "MicroRNAs and phylogenomics resolve the relationships of Tardigrada and suggest that velvet worms are the sister group of Arthropoda", "Phylogenomic Interrogation of Arachnida Reveals Systemic Conflicts in Phylogenetic Signal", "Arthropod fossil data increase congruence of morphological and molecular phylogenies", "A Critical Appraisal of the Placement of Xiphosura (Chelicerata) with Account of Known Sources of Phylogenetic Error", The genome of a daddy-long-legs (Opiliones) illuminates the evolution of arachnid appendages and chelicerate genome architecture, Spectacular alterations in the female reproductive system during the ovarian cycle and adaptations for matrotrophy in chernetid pseudoscorpions (Pseudoscorpiones: Chernetidae), "Almost a spider: a 305-million-year-old fossil arachnid and spider origins", "Three-dimensional reconstruction and the phylogeny of extinct chelicerate orders", "A phylogenetic analysis of the arachnid orders based on morphological characters", Department of the Environment and Heritage, https://en.wikipedia.org/w/index.php?title=Arachnid&oldid=1138961391, This page was last edited on 12 February 2023, at 16:52. If the animal is allowed to survive after spinning its cocoon and through the pupal phase of its lifecycle, it releases proteolytic enzymes to make a hole in the cocoon so it can emerge as an adult moth. First mentions of silkworms domestication are dated to more than 5000 years before our era, originating from Chinese regions (Yu et al. Researchers at the MIT Media Lab experimented with silkworms to see what they would weave when left on surfaces with different curvatures. Speaking of silk moths with stunning eye spots, Io moths are known for their venomous caterpillars. She was drinking tea under a tree when a cocoon fell into her tea. Its uses are to dispel flatulence, dissolve phlegm, and relieve spasms. No animals suffer or die for the silk to be produced, making it a favorable alternative to normal silk for those who object to harming animals. Field of Dreams; A History of Deafblindness in Scotland; Deafblindness. Under natural conditions, they have one generation per year, with the females laying 200 to 500 eggs (Grzimek et al. Of course, those people have to spend much money cleaning it. Silk-fiber is a protein produced from the silk-glands of silkworms. This is because their bodies are too big and heavy for their small wings. Silkworms eat mulberry leaves, and are native to northern China. When the silkworm is spinning through the spinning tube, due to some mechanical actions such as dehydration and drafting, a secondary solidification structure occurs, forming a layered shape. [22] The eggs are kept in incubators to aid in their hatching. 2004). Rinse it with clear water, and repeat this steps if necessary. The Japanese thus began their love affair with silk. Silkworm definition: A silkworm is the young form of a Chinese moth and it produces silk. Their body is organized into two tagmata, called the prosoma, or cephalothorax, and the opisthosoma, or abdomen. In scorpions, pseudoscorpions, and ricinuleids the pedipalps ends in a pair of pinchers, and in whip scorpions, Schizomida, Amblypygi, and most harvestmen, they are raptorial and used for prey capture. Heres how to get wrinkles out of silk. The adult phase (the moth) cannot fly. This method not only can remove stains but also can maintain the life of the pillowcases. Like many insect species, silkworm pupae are eaten in some cultures. The silkworm is the larva or caterpillar of a silk moth. Most spiders have eight eyes, but some, like the brown recluse spider, only have six. [53], "Arachnida" redirects here. Adult Bombycidae have reduced mouthparts and do not feed. [3], Almost all adult arachnids have eight legs, unlike adult insects which all have six legs. The fashionable and novel styles with narrow waist, round shoulders and low collar reflect the youthful, pure and energetic personality of young people. The collar, Hairstyle If you wear a traditional long silk cheongsam, you must consider the beauty of the classical temperament of the cheongsam, and it is recommended to try up-do; if you wear a short modified cheongsam, then you must consider the beauty of modern fashion, you can try a long hairstyle. [11] Except for a pair of pectines in scorpions,[12] and the spinnerets in spiders, the abdomen has no appendages. Silk moth pupae are edible insects and are eaten in some cultures: Silkworms have also been proposed for cultivation by astronauts as space food on long-term missions.[35]. Molecular phylogeny of silkmoths reveals the origin of domesticated silkmoth. Many hundreds of strains are maintained, and over 400 Mendelian mutations have been described (Goldsmith et al. In areas where the climate is always warm, the moths life cycle is ongoing. [9] A telson is present in scorpions, where it has been modified to a stinger, and into a flagellum in the Palpigradi, Schizomida (very short) and whip scorpions. Of course, we cannot! The individual silkworm silk fibers (brin) are 10-12 m in diameter with a triangular cross section, resulting in a composite fiber (bave) of up to 65 m in diameter. Sericulture, the practice of breeding silkworms for the production of raw silk, has been under way for at least 5,000 years in China,[1] whence it spread to India, Korea, Nepal, Japan, and the West. At least 70 million pounds of raw silk are produced each year, requiring nearly ten billion pounds of mulberry leaves. I love to write and share science related Stuff Here on my Website. arachnid: [noun] any of a class (Arachnida) of arthropods comprising chiefly terrestrial invertebrates, including the spiders, scorpions, mites, and ticks, and having a segmented body divided into two regions of which the anterior bears four pairs of legs but no antennae. Mix equal parts ammonia and water in a bowl. The Chinese guarded their knowledge of silk. Januar 2023 . Deep sleep is the stage when a person sleeps the most soundly and soundly. Silkworms, on the other hand, are natural silk-spinning factories. The cocoon of the domesticated silkworm is made of a single continuous thread of raw silk from 300 to 900 meters (1000 to 3000 feet) long. [citation needed], Many research works have focused on the genetics of silkworms and the possibility of genetic engineering. Usually, silkworms can stay in any container as long as you provide them fresh food. Sericulture is the term used for the culture of silkworms for silk production. Thus, before removing stains, you should read the care tag carefully. They also created implants made of silk and drug compounds which can be implanted under the skin for steady and gradual time release of medications.[14]. Silkworm Bombyx mori Generally only the silk of moth caterpillars certaining insect larvae to form cocoons has been used for textile manufacturing. Steps to Clean 100% Pure Silk Clothing Place 100 percent silk. Eclosion The pupa period of silkworms is generally about 2 weeks. Studies have shown that during deep sleep, human cerebral cortex cells are in a state of full rest, various life activities are reduced to a minimum, and the, Sleep is a spontaneous and reversible resting state that occurs periodically in higher vertebrates, which is manifested as a decrease in the bodys responsiveness to external stimuli and a temporary interruption of consciousness. . Using a rough figure of one kilometer of silk (about 3300 feet) per cocoon, ten unraveled cocoons could theoretically extend vertically to the height of Mt Everest. Active substances such as enzymes, carriers and certain hormones are all proteins, which are indispensable substances for the maintenance of life processes. The native color pigments have also been lost, so the domestic silk moths are leucistic, since camouflage is not useful when they only live in captivity. Many more legends about the silkworm are told. What they all have in commonand what distinguishes them from insectsare four pairs of legs and. ISBN links support NWE through referral fees. The domestic silk moth (Bombyx mori) is an insect from the moth family Bombycidae. The excretory glands of arachnids include up to four pairs of coxal glands along the side of the prosoma, and one or two pairs of Malpighian tubules, emptying into the gut. Preheat the iron to medium, and make ensure that the steam option is, After a long time of stock and packing, silk will wrinkle. [15] Antibiotics such as lysocin E,[16] a non-ribosomal peptide synthesized by Lysobacter sp. Notable examples are: Due to its large size and ease of culture, Bombyx mori has long been a model organism in the study of Lepidopteran and arthropod biology (Goldsmith et al. The domestic silk moths cannot fly, so the males need human assistance in finding a mate, and it lacks fear of potential predators. Although native to China, the silkworm has been introduced throughout the world and has undergone complete domestication, with the species no longer being found in the wild. When he saw her, he tried to rape her but she was able to escape and hidden by the mountain god. After they have molted four times (i.e., in the fifth instar), their bodies turn slightly yellow and their skin becomes tighter. There are many more legends about the silkworm. Hatchlings and second-instar larvae are called kego (, "hairy silkworm") in Japan, or chawki in India. Mahatma Gandhi was critical of silk production based on the Ahimsa philosophy "not to hurt any living thing". [9] Another source suggests 1,000 inbred domesticated strains are kept worldwide. Age Young women can choose those colorful cheongsam. Goldsmith, M. R., T. Shimada, and H. Abe. It is entirely dependent on humans, and it no longer lives in the wild. A study in 2014, based on the largest set of molecular data to date, concluded that there were systematic conflicts in the phylogenetic information, particularly affecting the orders Acariformes, Parasitiformes and Pseudoscorpiones, which have had much faster evolutionary rates. The primary nitrogenous waste product in arachnids is guanine. The silkworm is the larva or caterpillar of a silkmoth. Try the laundry soap you use to regularly clean the sheets but in a little more concentrated form, once the lipstick and makeup stain has set. [4]:342, Domestic silk moths are very different from most members in the genus Bombyx; not only have they lost the ability to fly, but their color pigments have also been lost. Step to Remove a Water Stain from Silk Fabric Place the silk fabric with water stains on the ironing board. The moth the adult phase of the lifecycle is not capable of functional flight, in contrast to the wild B. mandarina and other Bombyx species, whose males fly to meet females and for evasion from predators. New World Encyclopedia writers and editors rewrote and completed the Wikipedia article The endosternite is even calcified in some Opiliones. Credit is due under the terms of this license that can reference both the New World Encyclopedia contributors and the selfless volunteer contributors of the Wikimedia Foundation. Silkworm reproduces its offspring with eggs, and there are two types of silkworm eggs, diapause eggs and non-diapause eggs. Instead, commercially reared silkworm pupae are killed before the adult moths emerge by dipping them in boiling water, thus allowing the whole cocoon to be unraveled as one continuous thread. It is thought that the secondary sets of eyes are derived from the compound eyes of a common ancestor to both spiders . [11], Kraig Biocraft Laboratories[12] Bombyx mori is essentially monophagous, exclusively eating mulberry leaves (Morus spp.). [8], Due to its small size and ease of culture, the silkworm has become a model organism in the study of lepidopteran and arthropod biology. The environmental temperature directly affects and basically determines the body temperature of the silkworm. The most dangerous caterpillar in the world is the Assassin or Lonomia obliqua, also from the Saturniidae family. However, true silkworms only feed on the leaves of white mulberries. The domesticated B. mori and the wild B. mandarina can still breed and sometimes produce hybrids. In the pupa stage, a weave is netted all around itself by the silkworm to hold itself. The fibers are very fine and lustrous, about ten micrometers (1/2500th of an inch) in diameter. "Molecular phylogeny of silkmoths reveals the origin of domesticated silkmoth, "Captive breeding for thousands of years has impaired olfactory functions in silkmoths", "Cocoon Silk: A Natural Silk Architecture", "The genetics and genomics of the silkworm, Bombyx mori", "Advantages of the silkworm as an animal model for developing novel antimicrobial agents", "A novel spiro-heterocyclic compound identified by the silkworm infection model inhibits transcription in, "Pharmacokinetic parameters explain the therapeutic activity of antimicrobial agents in a silkworm infection model", "YjbH regulates virulence genes expression and oxidative stress resistance in Staphylococcus aureus". The caterpillars feed on leaves of mulberry trees, with the preferred food being the white mulberry. Sometimes, the wild silkmoth is considered a subspecies of Bombyx mori as they are theoretically capable of full hybridization. Silk is a helical thread produced by silk glands. If the fabric is not completely degummed, fishy smell will remain on the raw, Can you tell the difference between satin and silk nightgowns? In . Beneath this is a transparent vitreous body, and then the retina and, if present, the tapetum. Bombyx mori females are also one of the few organisms with homologous chromosomes held together only by the synaptonemal complex (and not crossovers) during meiosis. In most species, the male transfers sperm to the female in a package, or spermatophore. [4] In Solifugae, the palps are quite leg-like, so that these animals appear to have ten legs. Silkworms (incorrectly spelled silk worms) are the larval form of the domesticated silk moth, Bombyx mori. edit the questions; save a copy for later; start a class game; view complete results in the Gradebook and Mastery Dashboards; automatically assign follow-up activities based on students' scores This led to Gandhi's promotion of cotton spinning machines, an example of which can be seen at the Gandhi Institute,[7] and an extension of this principle has led to the modern production practice known as Ahimsa silk, which is wild silk (from wild and semiwild silk moths) made from the cocoons of moths that are allowed to emerge before the silk is harvested. About 2,000 to 3,000 cocoons are required to make 1 pound of silk (0.4kg). . The genome has been sequenced (Mita et al. Silkworm: Some male insects can recognise their females by their smell. The route from the East China Sea began at the latest when the King of Zhou Wu killed Zhou. is silkworm an arachnidjacob wilson car accident lexington, ky. is silkworm an arachnidonce in a lifetime game hospital door code. While they prefer white mulberry (Morus alba), they also will consume leaves of other species of Morus (the mulberry genus) and some other Moraceae (the mulberry family). If the ingested protein exceeds the need to maintain tissue growth, renewal and repair, or when the energy storage material in the silkworm, Although real silk has excellent natural health care properties, it will also encounter some problems in use, such as: real silk is easy to fade, easy to fluff and white after washing, poor light fastness, easy to shrink, easy to get brittle, etc. For instance: a pen falls, leaving a stain across the silk dress. [10] At the base of the flagellum in the two latter groups there are gland who produce acetic acid as a chemical defense. . Recent research has also shown that sericulture can be developed as a highly rewarding agro-industry. This toxin causes unbelievable pain in humans, so imagine what it would do to a predator like a bird or small mammal. Bivoltine varieties are normally found in East Asia, and their accelerated breeding process is made possible by slightly warmer climates. Place sweat-stained silk bed sheets on a work surface, and keep the sweat stain facing up. [30] Major questions, however, remain unanswered, according to Jun Wang, co-author of a related study published in 2008,[31] who stated: "Whether this event was in a single location or in a short period of time in several locations cannot be deciphered from the data",[32] and research also has yet to identify the area in China where domestication arose. If youve been looking for an interesting summertime project for your family, you should consider keeping silkworms as pets. The silkworm is the larva or caterpillar of a silk moth. Spiders and silkworms spin silks that outcompete the toughness of all natural and manmade fibers. Arachnids produce digestive enzymes in their stomachs, and use their pedipalps and chelicerae to pour them over their dead prey. Naked and cold, she spit out the net and used it as a blanket to sleep. 2004). High-resolution silkworm pan-genome provides genetic insights into artificial selection and ecological adaptation | Nature Communications article Article Open Access Published: 24 September 2022. However, molecular phylogenetic studies suggest that the two groups do not form a single clade, with morphological similarities being due to convergence. The Uraraneida are an extinct order of spider-like arachnids from the Devonian and Permian. The eggs are covered with gelatinous secretion by which they stick to the leaves. Injury from exposure to these moths spines can be significant. silkworm moth, ( Bombyx mori ), lepidopteran whose caterpillar has been used in silk production ( sericulture) for thousands of years. [5], Mulberry silkworms can be divided into three major categories based on seasonal brood frequency. It is difficult to remove tough stains such as grease because of the fine nature of silk. Yoshitake, N. 1968. 1. They are not monophagous, since they can eat other species of Morus, as well as some other Moraceae, mostly Osage orange. The first pair, the chelicerae, serve in feeding and defense. Some mites have no heart at all. The lateral ocelli evolved from compound eyes and may have a tapetum, which enhances the ability to collect light. Quantity of cocoon and silk produced are directly related to the pupation rate and larval weight. Finally, slit sense organs are slit-like pits covered with a thin membrane. When the color of their heads turns darker, it indicates they are about to molt. According to records of the time when Chinese silk was spread out in the 4th century BC, it was introduced to India and Western countries, and became famous all over the world. China According to Chinese myth, sericulture and the weaving of silk cloth was invented by Lady Hsi-Ling-Shih, the wife of the mythical Yellow Emperor who is said to have ruled China in about 3,000 BC. It is estimated that 98,000 arachnid species have been described, and that there may be up to 600,000 in total. . In the U.S., teachers may sometimes introduce the insect life cycle to their students by raising domestic silk moths in the classroom as a science project. Horse in Chinese mythology Origins of sericulture. The final molt from larva to pupa takes place within the cocoon, which provides a vital layer of protection during the vulnerable, almost motionless pupal state. Sarah Underhill Wisseman, Wendell S. Williams. Adults emerge from the cocoon after about three weeks, reproduce, and then die within five days (Grzimek et al. However, due to the domesticated moth's requirement for human care to survive, gene flow is all but nonexistent and thus, despite its apparently recent origin, the domestic animal is generally treated as a distinct monotypic species today. They are totally dependent on humans; there are no wild populations. It is the closest relative of Bombyx mandarina, the wild silk moth. And we usually get new silk fans with wrinkles since they are flat-packed for transportation and storing which can save shipping cost. Caterpillars of Bombyx mori are about four centimeters (1.5 inches) in length, with a pale brown coloration and brown marks on the thorax (Grzimek et al. Steps of Cleaning Silk Pillowcases Mix 2 tsp. The arachnid subdivisions are listed below alphabetically; numbers of species are approximate. Roughly 3,000 silkworms are killed to make a single pound of silk. Treat stains as soon as, It is not an easy task to remove stains from clothes. Thus, even oily stains such as oil, lotion, salad dressing and butter can be easily removed. Dry Cleaning Process Pretreatment, also known as stain removal. The nearest wild relative of Bombyx mori is Bombyx mandarina, the wild silkmoth, which is able to hybridize with the domestic taxon (Goldsmith et al. About 1/3 of human life is spent in sleep. In some arachnids, the oesophagus also acts as an additional pump. In China, a legend indicates the discovery of the silkworm's silk was by an ancient empress named Leizu, the wife of the Yellow Emperor, also known as Xi Lingshi. With the exception of scorpions, which can have up to five pairs of lateral ocelli, there are never more than three pairs present. roots and other parts of mulberry trees, including more than 200 species belonging to Insecta, Arachnid and Gastropod. Satin Nightgowns Silk Nightgowns Production It is made by man from nylon and polyester being woven together. Currently, research is focusing on genetics of silkworms and genetic engineering. [34], Arachnids usually lay yolky eggs, which hatch into immatures that resemble adults. They comprise over 100,000 named species, of which 47,000 are species of spiders. This allows a much stronger cloth to be woven from the silk. Recently, silkworm Bombyx mori silk has caught attention owing to its natural enormous production, excellent biocompatibility and unique mechanical properties. The silkworm is the larva (the active immature form of an insect) or caterpillar of the Bombyx mori moth. However, you can follow the instructions below to remove stains, How to get sweat stain out of silk sheets? 20-40min before eclosion, the color of the feet, wings and abdomen becomes brown and milky. It is not known when the domestic silkmoth diverged from its wild relatives, only that the domestic population originated from inland Chinese rather than Japanese or Korean stock (Maekawa et al. It can be difficult to remove odor (smoke or body odor) from silk clothes due to its delicate nature. Mita, K., M. Kasahara, S. Sasaki, Y. Nagayasu, T. Yamada, H. Kanamori, N. Namiki, M. Kitagawa, H. Yamashita, Y. Yasukochi, K. Kadono-Okuda, K. Yamamoto, M. Ajimura, G. Ravikumar, M. Shimomura, Y. Nagamura, T. Shin-i, H. Abe, T. Shimada, S. Morishita, and T. Sasaki. For millennia, arthropod (arachnids, insects and myriapods) silk has been known to humans as an exceptional biomaterial. The Chinese guarded their knowledge of silk, but, according to one story, a Chinese princess given in marriage to a Khotan prince brought to the oasis the secret of silk manufacture, "hiding silkworms in her hair as part of her dowry", probably in the first half of the first century AD. [36] About AD 550, Christian monks are said to have smuggled silkworms, in a hollow stick, out of China and sold the secret to the Byzantine Empire. 1988; Arunkumar et al. 2004. Silkworm Silkworm Introduction A material which is composed of thin and continuous strands is known as fibre. [20], Arachnids may have one or two gonads, which are located in the abdomen. Bombyx mori (Latin: "silkworm of the mulberry tree") of the Bombycidae family feeds solely on the leaves of mulberry trees and produces the finest, most lustrous fiberthe major source of commercial silk. For the arachnida curve, see, Last edited on 12 February 2023, at 16:52, Invertebrate Zoology: A Tree of Life Approach, Morphological support for a clade comprising two vermiform mite lineages: Eriophyoidea (Acariformes) and Nematalycidae (Acariformes), The Colonisation of Land: Origins and Adaptations of Terrestrial Animals, Homeosis in a scorpion supports a telopodal origin of pectines and components of the book lungs, Fossil evidence for the origin of spider spinnerets - Nature, "Mechanics of Cuticular Elastic Energy Storage in Leg Joints Lacking Extensor Muscles in Arachnids", "Muscle Firing Patterns in Two Arachnids Using Different Methods of Propulsive Leg Extension", "Elastic energy storage in the pedipedal joints of scorpions and sun-spiders (Arachnida, Scorpiones, Solifugae)", "Early Terrestrial Animals, Evolution, and Uncertainty", Feeding habits and multifunctional classification of soil-associated consumers from protists to vertebrates, Diet, predators, and defensive behaviors of New Zealand harvestmen (Opiliones: Neopilionidae), How do harvestmen hunt? The average silkworm crop loss in India due to diseases is to the tune of 15-47%, while it is 10-15% in other countries like Japan, China and Italy. Silkworm breeding is aimed at the overall improvement of silkworms from a commercial point of view.
