JOURNAL FREE ACCESSThe effects of the dietary levels of protein and pyridoxine (B6) on growth and survival of the 5th-instar larvae of the silkworm were studied under aseptic condition. The silkworms were reared with the twenty-four different diets containing 15 to 60% of protein in combination with 0 to 1mg B6 per g of the dry diet. When the larvae reared on the diet containing 30, 45, and 60% protein, they grew well at B6 levels of 10, 100μg, and 1mg, respectively. All the larvae died with the diet containing less than 0.1μg of B6 before pupation. Mortality of larvae was very high when they fed on high protein and low B6 diet. Mortality of larvae was lowered with the increase of protein content in the diet. When the dietary protein level was low, excess amounts of B6 showed slightly an inhibitory effect on the larval growth. Female larvae required a higher amount of B6 than male larvae throughout the development. Minimum quantity of B6 for survival ranged from 6 to 8μg in female and from 4 to 6μg in male larvae. Larvae needed more amounts of protein and B6 for the growth of silkgland, than those for the other tissues.View full abstractDownload PDF (820K) -

JOURNAL FREE ACCESSThe latex agglutination test was employed to detect microsporidian spores in Nosema bombycis (Nb), Nosema sp. M 11 (M 11), and Vairimorpha sp. M 12 (M 12) infected mother moth. On the slide agglutination test, Nb, M 11, and M 12 spore specific monoclonal antibody-sensitized latex particles were specifically attached to the spores isolated from homogenate of Nb, M 11, and M 12 infected mother moth, respectively. Our slide agglutination test using the monoclonal antibody-sensitized latex particles will be useful for a practical technique of pebrine inspection.View full abstractDownload PDF (446K) -

JOURNAL FREE ACCESSFeeding response to an artificial diet which contained 2-10% of fish meal, yeast, pupal powder, rape bran, gluten meal and alfalfa, and subsequent larval growth were investigated in newly-hatched larvae of original strains, hybrid races, and polyphagous strains. The results showed that Japanese strains such as Sawa J and N 01 were able to grow on all of the diets unlike the larvae of the Chinese strain (C 01). Some larvae of hybrid races grew on diets containing rape bran, gluten meal, and yeast, whereas almost all of the larvae used did not survive on the other diets. Polyphagous strains showed a high feeding ability and survival rate on these diets. Furthermore, the feeding ability and survival rate of polyphagous strains increased, when 5% of mulberry leaf powder was added to the diets. Based on these results, it was concluded that feed ingredients for livestock could be used partly in artificial diets, in which the content of mulberry leaf powder was reduced to less than 5% in the case of polyphagous strains.View full abstractDownload PDF (653K) -

JOURNAL FREE ACCESSVariations in susceptibilities of the various silkworm strains to peroral infection with a nuclear-polyhedrosis virus (NPV) were relatively large when the larvae were fed on artificial piets instead of mulberry leaves. The larvae reared on artificial diets were more susceptible to peroral infection with NPV than those reared on mulberry leaves, and the difference in susceptibility between them increased with larval age. However, no difference in susceptibility to intrahemocoelic infection with NPV was observed of the both larvae, suggesting food quality is important in the susceptibility of larvae to peroral infection with NPV. The gut juice from the larvae fed on mulberry leaves was significantly higher in the antiviral activity than that from the larvae fed on artificial diets. The antiviral activity of the gut juice seemed to be depended on a protease.View full abstractDownload PDF (547K) -

JOURNAL FREE ACCESSRecently, filature factories have many problems in daily work because of decrease of the cocoon cooking experts. Irregularity in size and quality of cocoon, which is caused by decrease the cocoon production in each sericultural farm household, accompanied by great difficulty in cocoon cooking technique. In order to solve these problems, the authors introduced an expert system by means of applying principal component analysis into the cocoon cooking process. This system is a computer aided consulting one in the process, and contains theoretical and experienced knowledge of experts in the cocoon cooking. Namely, the system infers the correct prescription by using the theoretical and experienced knowledge of experts, and solves the technical problems instead of the cocoon cooking experts. In this paper, this system was applied to a filature factory, and an examination was made of the relationship between the reeling results and the cocoon cooking technique. As a result, it was confirmed that the expert system was useful for supporting unskilled engineers in the filature factory.View full abstractDownload PDF (648K) -

JOURNAL FREE ACCESSIn this paper, in order to find the optimum temperature pattern of the cocoon cooking, the authors examined the method finding the optimum temperature pattern based on the fuzzy theory from among the various temperature patterns derived from multivariate analysis. The results obtained were as follows: 1) Three temperature patterns were derived from principal component analysis for regression. Each partial regression coefficient was normalized by the mean value, and the normalized value corresponded to the base of discrete fuzzy variables. 2) In order to reduce the number of fuzzy rules, the discrete fuzzy variables of conditional part of the rule was defined three ones, and each variable was divided into seven grades. 3) Based on the above methods, the program was developed, an examination was made of finding the optimum temperature pattern of the cocoon cooking on the basis of the data. Consequently, the temperature pattern that the authors considered best empirically was matched with the inference result by computer.View full abstractDownload PDF (526K) -

JOURNAL FREE ACCESSA computer controlled data acquiring system was developed to collect information for filature factories. This system is composed of two parts, the data collection of water temperatures in addition to the pH values of the cocoon cooking machine, and the data count of the feeding end and the reel stop on the autmatic reeling machine. This system can also indicate to the operator the irregular operation of each reeling machine that is individually set with a flashing light and buzzer. In consideration for the feasibility of maintenance and software productivity, the data processing program was written in BASIC. The problem of mechanical and electric noise in the factory which causes data transfer errors was investigated, and the trouble shooting circuit was applied to this system. After investigating the fundamental functions, it was confirmed that a real time data collection system for monitoring filature factory operations could be constructed using a computer and I/O devices.View full abstractDownload PDF (805K) -
