Antheraea yamamai silkworm cocoon is considered as a natural biocompatible materials, but can not be used as medical resources due to its difficult processability. In this study, we examined the general characteristics including cocoon shell weight and structural and thermal properties of Antheraea yamamai silkworm cocoon. The cocoon shell weight and thickness of wild silkworm cocoon was 0.528 g and 0.424 mm, respectively. The cocoon has yellow-green color in outside cocoon but white in inner layer cocoon. Amino acid analysis showed that the main amino acid of Antheraea yamamai cocoon is alanine, glycine, serine, aspartic acid, tyrosine and arginine. X-ray diffractometry showed that strong diffraction peaks at
, corresponded to
-sheet structure and sharp diffraction peaks at
due to the presence of calcium oxalate on cocoon surface. Antheraea yamamai cocoon was degraded at
. These results might be used as basic information for development of non-textile materials using Anthereae yamamai silkworm cocoon.

This study was conducted to consider practical use of F2 hybrid and intervariety crossing for the improvement of silkworm eggs export and silkworm eggs manufacture. Now Kumokjam and Baegokjam come into wide use to sericulture farmers but comparison test of F1, F2 hybrid and intervariety have not been done. We weighed against the productivity among economical character. While larval period of F2 among them is most long time, pupation percentage and cocoon yield per 10,000 3rd molted larvae are lower than intervariety. With comparing F2 and intervariety, single cocoon weight of F2 is lower 9 ~ 21% than intervariety, and cocoon shell weight of F2 was lower 10 ~ 18% than intervariety. By number of cocoons per liter, F2 hybrid was lower and more irregular size than intervariety. In coparison with number of egg laid, F2 hybrid Baegokjam was 655 ea (14%) and Kumokjam 625 ea (40%) more than F1 hybrid. Also, F2 hybrid for filament grade went down than F1 hybrid. The advantage of egg production in F2 hybrid can reduce costs because there is no necessity for sex discrimination and germination control. But besides increase of number of egg laid, the productivity including economical characters was greatly lowered. Except for being a lot of laying eggs, cocoon productivity of the F2 was greatly reduced by degeneration of practical traits. Therefore the further studies are needed in order to increase utilization value of the F2 hybrid silkworm.

Though mulberry fruit is known to a by-product that was produced from mulberry tree after harvesting leaves for silkworm rearing, as a yield and consumption of mulberry fruit was increased, it has been fixing to a new income crop. But, a stable production of mulberry was issued on damage by the weather disaster, so it is requires that agricultural disaster insurance import. So, in this study as a basic research for a importation of agricultural disaster insurance, the cultivation of mulberry for the production of mulberry fruits, the shape of tree, the number of a bearing fruit from each cultivar, the occurrence of mulberry fruit sclerotic disease, and a yield and the market price of mulberry fruits were investigated and that results obtained were as follows; The number of mulberry tree each 10a was abundant in Buan and Jeongeup region that cultivated a suitable cultivar on low cut shape, however, a large cultivated Gochang region was little. The number of a bearing fruit per 1m on the branch was highest in the variety of Cheongilppong at Gochang. Yield of mulberry fruits each 10a was Cheongilppong at Gochang, followed by Iksuppong at Sangju. Average sale price of the mulberry fruits was high in the order of Gwasang No. 2, Suwonppong, Iksuppong, and Cheongilppong.

Since based on the revised educational curriculum, the insects and spiders in eight biology textbooks I and II of high school are as follows. In class level, two classes, Insecta and Arachnida were investigated and their frequence numbers in the textbooks were a total of 143 times. In order level, 12 orders in insecta, 2 orders in Aranea were appeared in the textbooks. The most appearing frequence number was represented in Lepidoptera (33 times) and then in Araneae (11 times). For each publisher, the most appearing frequencies of insecta and spiders was shown in Gyohaksa (23 times), and then in Hyeongseol and Centurla education research institute (21times, respectively). In the textbooks, four species were found to misidentify in their species name and five mistakes were investigated in their photos and content.

To increase the income of sericultural farms and expand sericulture industry, new high value-added products of sericulture which are beyond current products like 5th instar 3 day dried silkworm, male pupa and silkworm dongchunghacho are needed. For this sericulture product diversification, it is in desperate need of the edible processing method after 5th instar 4 day silkworm that silkgland formation is rapidly in progress during the larva periods. So far it was hard to eat because of silkgland formation in their body. So we try to boil and steam frozen-, dried-, and living-silkworm to develop low-cost edible processing methods for farmers. As the result, the silkgland of frozen and dried silkworm was not degenerated, so silkgland in their body was not edible. But in the case of living silkworm, the silkgland of mature silkworm was degenerated by boil and steam treatment, so the body and silkgland of silkworm were not only edible but also tasted good. Then the dried silkworm was easily powdered and there was no problem when it was eaten. This source technology can be widely used in the general food industry, health functional food cosmetics, pet food and so on, so it is predictable that this will contribute to increase the income of sericulture farms and expand sericultural industry.

We characterized tissue specific-expressed genes in the posterior silk gland of Bombyx mori using by the Annealing Control Primer based differential display-PCR manner. In this study, we isolated 34 differentially expressed PCR amplicons, which one of these was identified as a novel transcript named as ACP-16 (366 bp), its expression was observed only in the posterior silk glands by Northern blot analysis. To determine promoter region of the ACP-16, we isolated and analyzed a phage DNA having 1.7 kb-long genome DNA including the open reading flame and 5'- upstream untranslated region of the ACP-16 gene from a genomic DNA library. We have estimated a promoter region of the ACP-16 gene by a web promoter prediction engine, which locates -750 ~ -165 from translation initiation site (ATG, +1). ACP-16 gene is necessary to more studies about critical biological role in order to apply the silkworm's transgenic system.

Mulberry fruit is common to keep a frozen storage because of the very high water content. Because freezing-storing cost is generated before the processing or sales, farmers of mulberry fruit production are weighted in financial burden. In addition, mulberry fruit has difficulty in expanding consumption by made in the simple processed products like the mulberry jam, mulberry juice, mulberry enzyme, alcohol, etc. Recent, frozen fruits including frozen blueberries, frozen strawberries, frozen mango, frozen rich, frozen mulberry fruit has been started to sell in the large discount stores and convenience stores. However, there is restricted sales in only special place that have the frozen distribution facilities. So, for the income improvement and consumption promotion of mulberry farmers facing these difficult situations, we developed the processing method of semi-dried mulberry fruit using the vacuum freezing dryer. The frozen mulberry fruit which was stored below
is to dry in a vacuum freeze dryer, at
, 23 ~ 24 hours. Semi-dried mulberry fruit seperated respectively. It had soft texture, and maintained shape, size and flavor. In particular, semi-dried mulberry fruit can be stored at room temperature.

Melittin is the main component of Bee Venom and has antibacterial activity against several bacteria. To produce the melittin antimicrobial peptide, we constructed transgenic silkworm that expressed melittin gene under the control BmA3 promoter using piggyBac vector. The use of the 3xP3-driven EGFP cDNA as a marker allowed us to rapidly distinguish transgenic silkworm. Mixtures of the donor vector and helper vector were micro-injected into 300 eggs of bivoltin silkworms, Baegokjam. In total, 131 larvae (G0) were hatched and allowed to develop into moths. The resulting G1 generation consisted of 36 broods, and we selected 4 broods containing at least 1 EGFP-positive embryo. The rate of successful transgenesis for the G1 broods was 11%. We identified 12 EGFP-positive G1 moths and these were backcrossed with wild-type moths. With the aim of identifying a melittin as antimicrobial peptide, we investigated the Radical diffusion Assay (RDA) and then demonstrated that melittin possesses high antibacterial activities against gramnegative bacteria.
