The southern Silk Road kingdom of Khotan was long considered by Chinese pilgrim monks to be just another stop on the road to India in search of Buddhist scriptures. The aim of this dissertation is to recast Khotan as a unique and innovative mediator of religious and cultural expression within the Buddhist network through an analysis of the Khotanese silk princess narrative, the tale of an eastern princess who is credited with acquiring the secrets of Chinese sericulture for the Khotanese king.

Die Serikultur, Produktion und Verarbeitung von Seide durch Ernährung der Seidenraupen mit Maulbeerblättern, hat ihren Ursprung in China. Von dort aus breitete sie sich jedoch in vielen anderen Ländern aus. Die Arbeit konzentriert sich auf einen Fall Indonesiens, analysiert die Prinzipien des Projektzyklus'' des BSA-Projekts in Zentral-Java, um durch Verknüpfung von induktiver und deduktiver wissenschaftlicher Vorgehensweise zu ermitteln, wie ein Projekt praktisch hinsichtlich grundlegender Methoden und ihrer Generalisierbarkeit analysiert werden kann. Ziele der Arbeit sind zunächst die Darlegung der Implementierung der Entwicklungsziele in einem konkreten Fall. Weiteres Ziel ist die Veranschaulichung der Ergebnisse einer Investitionsanalyse, um auf der Basis aller durchgeführten Analysen die Rolle der Serikultur als Annäherung zum Ziel der potentiellen Cash-Gewinnung und Armutsreduzierung in Zentral-Java zu beurteilen. Es wurde eine Investitionsanalyse und Sensitivitätsanalyse nach drei unterschiedlich Betriebsgrößen erstellt. Um einen Strategieplan zu entwickeln, wurde eine Regressionsanalyse anhand einer Evaluierung der Maulbeersorten Morus alba L. (Ma), Morus cathayana (Mc) and Morus multicaulis (Mm) und der optimalen Frequenz der Fütterung der Seidenraupen unternommen. Die institutionelle Organisationsleistung wurde anhand einer SWOT-Analyse (Strengths; Weaknesses; Opportunities; Threats) ausgewertet. Die sich daraus ergebenden Schlussfolgerungen wurden im Hinblick auf die zukunftsfähigen Unternehmungen im Projekt BSA dargestellt. / Sericulture, the production and processing of natural silk from silkworms feeding on mulberry leaves has its origin in China, but has spread to many other countries.

In the latter case, the silk cocoon, which is produced at the end of the 5th larval instar, is used in the production of various yarns and fabrics. This branch of Brazilian agribusiness, known as sericulture, is well developed in the state of Paraná, where it is a form of small-scale family farming. Several factors impact negatively on Brazilian sericulture, such as diseases during rearing, and B. mori is susceptible to a virus from the Baculoviridae family, namely, Bombyx mori multiple nucleopolyhedrovirus (BmMNPV), genus Alphabaculovirus (AlphaBV), which infects the larvae and jeopardises commercial production of the cocoon, causing losses to farmers and industry. Studies have proved that BmMNPV is polyorganotropic and there are several target organs, such as the tracheal system; however, details of its cytopathology are not known. The tracheal system is responsible for the aeration of the tissues of the insect. Thus, the present study aimed to describe the cytopathology of the tracheas of hybrid larvae of B. Mori, infected experimentally with BmMNPV, and isolated geographically in the state of Paraná. Fifth instar hybrid larvae were divided into two groups; one control, and the other inoculated. After ingestion, and on different days post-inoculation (dpi), from the 2nd to the 9th dpi, the larvae were anesthetized and dissected. Segments of organs such as the integument, muscle and silk gland, containing branches of the trachea, were collected and fixed in Karnovsky modified for transmission electron microscopy. On the 2st dpi, fresh hemolymph analysis was conducted in order to determine the susceptibility of the hemocytes. The results revealed that the hemocytes were infected from the 2nd dpi and the epithelial cells of the trachea were infected from the 4th dpi. The cytopathology of the tracheal cells showed hypertrophic nucleus, containing the viroplasm, the site of the synthesis of the nucleocapsids. Subsequently, the formation and development of the polyhedra occured, accentuating the nuclear hypertrophy and culminating in cell lysis. Virions were also observed, immersed in the basal lamina of the trachea, which appeared to be disorganized. Thus, the cytopathology of the trachea was consistent with the infection caused by AlphaBV, and the data that was obtained provides a better understanding of the infectious cycle of BmMNPV in the body of the insect. The time of infection, later for the hemocytes, and the presence of virions in the basal lamina of the trachea, indicated that this system is a secondary target for infection, and also that the hemolymph is an important dispersant of viral infection / Bombyx mori é um inseto da ordem Lepidoptera encontrado somente em bancos de germoplasma, sendo utilizado em pesquisas científicas e para fins comerciais. Neste caso, seu casulo de seda, construído ao final do 5º instar larval, é usado na produção de diversos fios e tecidos. Este ramo da agroindústria brasileira, conhecido como sericicultura, se apresenta bem desenvolvido no Estado do Paraná, estando incluído no programa de agricultura familiar. Vários são os fatores que exercem influência na sericicultura nacional, como as doenças, e B. mori é susceptível a um vírus da família Baculoviridae, o Bombyx mori multiple nucleopolyhedrovirus (BmMNPV), gênero Alphabaculovirus (AlphaBV). Ao infectar as lagartas o vírus compromete a produção comercial do casulo, causando prejuízos aos produtores rurais e a indústria. Estudos comprovam que o BmMNPV é poliorganotrófico e vários são os órgãos-alvos, como o sistema traqueal; entretanto, detalhes de sua citopatologia não são conhecidos. O sistema traqueal é responsável pela aeração dos tecidos do inseto e o presente estudo objetivou descrever a citopatologia das traqueias de lagartas híbridas de B. mori infectadas experimentalmente pelo BmMNPV, isolado geográfico do Paraná. Para tanto, lagartas híbridas de 5º instar foram divididas em dois grupos, controle e inoculado. Neste, o inóculo viral foi fornecido na alimentação e em diferentes dias pós-inoculação (dpi), do 2º ao 9º dpi, as lagartas foram anestesiadas e dissecadas; segmentos do tegumento, músculo e glândula da seda, contendo ramos da traqueia, foram coletados e fixados em Karnovsky modificado para a microscopia eletrônica de transmissão. No 2º dpi foi efetuada análise a fresco da hemolinfa, para averiguar a susceptibilidade dos hemócitos. Os resultados revelaram que os hemócitos se apresentaram infectados a partir do 2º dpi e as células epiteliais da traqueia a partir do 4° dpi. A citopatologia das células traqueais revelou núcleo hipertrófico, contendo o viroplasma, que é o local de síntese dos nucleocapsídeos. Posteriormente, houve a formação e o desenvolvimento dos poliedros, acentuando-se a hipertrofia nuclear e culminando com a citólise. Vírions também foram visualizados na lâmina basal da traqueia, que se apresentou desorganizada. Assim, a citopatologia da traqueia condiz com a infecção causada por AlphaBV, e as informações obtidas permitem um melhor entendimento do ciclo infeccioso do BmMNPV no corpo do inseto. O tempo de infecção, posterior ao dos hemócitos, e a presença de vírions na lâmina basal da traqueia, indicam que este sistema é alvo secundário e, ainda, que a hemolinfa se apresenta como um importante dispersor da infecção viral.

Sericulture is an important agro industry in Indian economy. Reeling sector is a vital component of sericulture linking the agriculture based activity of cocoon production with the industrial activity of fabric production. Reeling converts the cocoons into raw silk yam. Karnataka contributes about 63% of the silk production of the country and therefore the present study is focused on the silk reeling industry of Karnataka. Silk reeling sector, though provides a vital transformation, appear to be the weakest link owing to its innumerable problems and the limited value addition that takes place. Problems are associated with raw material availability, working capital constraints, marketing and quality related aspects. Reeling sector is input dependent activity and its operations are influenced heavily by three factors viz., cocoon quality, cocoon price and cocoon supply. However, there has not been adequate thrust on quality due to the absence of quality based price fixation. Absence of quality based pricing has been a major deterrent factor in the pursuit for quality improvement. The seasonality associated with cocoon quality, cocoon supply and price as also the raw silk price almost always determine the fate of reeling activity. Being aware of the limited research done in respect of Indian silk industry, an elaborate literature review in the area of economics and management aspects of the silk industry in general and silk reeling operations in particular, was made. Studies on the economics of reeling operations done in the past indicate negative net revenue for the reeling units. However, if the reeling industry has survived over the years, it cannot be in spite of the loss. The industry has to breakeven over a period of time to consolidate the gains, however meagre. So, it is worthwhile to study the economics of silk reeling industry over a sufficient period of time, that is enough to include a cycle of seasonality, be it with respect to cocoon quality, cocoon availability, cocoon price, raw silk demand or raw silk price. In addition, if the element of uncertainties at varying points of time is included to study their effect on reeling economics, it makes the study more meaningful. It may be noted that, the variations in cocoon price over a period of time are dictated by the seasonality with respect to cocoon supply and demand. With regard to the variations in cocoon price at a given point of time (within a season), price differential between the cocoon lots appears to be largely due to its quality. A study of the inter relationship between cocoon quality, its quantity and price as also raw silk price is important. It is therefore felt that, the relationship between the cost of cocoons, cocoon quality and its productivity, when built into the determination of reeling economics, the analysis will be more realistic. A study of a typical reeling unit, to unearth the intricacies of operations and decision-making in the light of the volatile situation in the industry forms a pre requisite for a clear understanding of its functioning. Since reeling activity is highly input dependent, ignoring the aspects of the input market dynamics would not yield a holistic perspective of the operations. If one has to study and understand the market dynamics, the attributes of the commodity transacted should be clearly known. The commodity in question here is cocoon. The quality of cocoons does not have a unique expression, either to consider as a variable for studying the relationships in the market or as an input into the production process or as a yardstick for commercial transactions. The thesis thus deals with three major aspects of silk reeling industry in Karnataka, relating to the quality of raw material, dynamics of market transactions and analysis of the day to day operations of a typical silk reeling unit. There are around five quality parameters used for testing the quality of cocoons and each of them has a certain dimension of importance in defining the quality of cocoons. The procedures followed in Japan and China are not readily adaptable for Indian conditions. Therefore, an attempt has been made to develop a unique measure of cocoon quality under Indian conditions both from the point of view of appropriateness of representation as also the ease of determination commercially. In view of the importance of shell ratio 9c (SR%) and defective cocoon % (DC%) in representing the quality of cocoons, these two quality parameters are used for fixing the cocoon quality index. The statistical technique chosen for developing the Cocoon Quality Index (CQI) is discriminant analysis. Data on SR% and DC9c in respect of a sample of around 40,000 lots of multibi cocoons spanning a period of two years were collected for the analysis. The objective was to group the cocoons into low, medium and high quality in addition to arriving at a discriminant function to represent the quality index from SR% and DC% as independent variables. The analysis has contributed in establishing an index for assessing and grading the quality of, both mutibi and bivoltine cocoons in the Indian context. The study has also brought to focus the fact that, SR% and DC% adequately represent the quality of cocoons. As an extension of the objective, the commercial application of CQI as a means of price fixation mechanism in the cocoon markets has been illustrated. An analysis of the quality of cocoon lots presently being transacted in Karnataka has been made. The study of the market dynamics focused first on estimation of the relationship between cocoon price and its quality and supply (quantity) and then establishment of the causal relationship between cocoon price and silk price. Day wise aggregate data were used in. these two instances. In addition, the relationship between lot size, quality and price of cocoons being transacted in the cocoon markets has been established using the lot wise micro level data. The interrelationships of the various time series data have been studied through ARIMA analysis. The asymmetry in response of raw silk price to changes in cocoon price has been studied. The study enabled the identification of the determinants of cocoon price and raw silk price which are the major factors contributing to the revenue of a silk reeling unit. The capability of the buyers to assess the quality of cocoons subjectively even in the absence of an analytical system, speaks about the experience and expertise of the reelers. The supply quantity of cocoons largely influences the cocoon price. The dependence of raw silk price on cocoon price indicates the predominance of the supply side of the industry. The symmetry in the response of raw silk price to changes in cocoon price has also been established. The problems typical of a reeling unit merit the application of simulation technique in order to gain insights into the operations of a reeling unit. Discrete Event System Simulation has been used with fixed time increment approach and terminating criteria. The operations of a typical silk reeling unit have been simulated for a period of one whole year. A typical model based on the heuristic thinking of reelers to reflect the practices ingrained in the reeling units has been developed. The strategies they adopt to counter the vagaries of their operations have also been considered. Silk reeling being an input controlled industry, the heuristics of cocoon buying decision has been incorporated as the core of the model. The heuristics are derived from discussions with several prominent reelers and observation of their operations. The model tries to incorporate the volatile situation of the cocoon market and the raw silk sale price as also the constraints of working capital and the decision the reeler tends to take under these conditions. Standard procedures of simulation viz., variance reduction techniques, verification and validation of simulation model etc. have been followed. Simulation experiments have been made considering the factors of strategies, working capital borrowed money and installed capacity, in order to study its influence on the performance of a reeling unit. The simulation experimental data have been initially subjected to rnultivariate analysis and later to univariate ANOVA for each of the two response variables viz., cumulative net revenue and cumulative capacity utilisation. The unique relationship between revenue and capacity utilisation indicated a trade-off between the two. The reeling unit has to aim at maximising utilisation without major setbacks in revenue. It has been found that the capacity utilisation of a reeling unit is influenced more significantly by the factors or parameters of the model viz., strategy, working capital, and borrowed money and plant capacity, while the variables of the model viz., cocoon price, CQI and raw silk price influence cumulative net revenue. The importance of cocoon quality for better economics of production has been clearly established which should serve as a guiding factor for cocoon buying decision. An interesting result is that when there is adequate working capital, a bigger batch size for raw silk sales earns higher net revenue. The seasonality in net revenue is overwhelming in all the cases. The reeling unit has positive net revenue in the first six months with a few ups and downs and the gain it had consolidated slowly reduces before stabilising at a relatively lower level. The important contributions are the development of a quality index for grading of cocoons, establishment of the interrelationships among cocoon price, its quality and supply quantity as also the relationship between cocoon price and raw silk price. The much needed insight into the operations of a reeling unit has been provided by the simulation analysis. For the first time it has been established that, reeling units do make profits from the primary product. The model incorporated good management decision making for the purchase of cocoons and handling of working capital and other operations.

This diploma thesis is focused on the silk production of invertebrates. The aim of the work is to systematically introduce important species and describe the purpose of their silk production. The ability to produce silk is widespread in many insect families. The production of proteinaceous fibers also occurs in arachnids and (in the form of byssus threads) also in mollusks. The Domestic Silk Moth (Bombyx mori) is an economically important insect, being a primary producer of silk. Hence, an integral part of the thesis focuses on Domestic Silk Moth. In this thesis all developmental stages of Silk Moth (from an egg to an adult) are described. In the past, efforts to breed silkworms also appeared in the Czech lands. Therefore, a short chapter of the thesis is devoted to the history of sericulture. Furthermore, this thesis describes methods of rearing silkworm larvae. For students of Natural Sciences and Biology, it is crucial to be in touch with live objects. Because the silkworm rearing is quite simple, it is possible to incorporate this topic to the school projects about holometabolous insects. The practical part of this thesis contains schedule of practical exercise about silk moths. And in final section of practical part, worksheets for lower-secondary students are presented.
