  • Biotechnological researches in Central Asian Research Institute of Sericulture were developed since 1981 when laboratory of artificial diets for mulberry silk­worm was created. The researches were directed not only to creation of accessible artificial diets (AD) for off-season mass rearing of economical beneficial insect and for industrialization of sericulture but also to obtaining of easy reproducible source of animal proteins, carbohydrates, lipids, enzymes, enzymes inhibitors and other metabolites - bioresource for manufacture of oriental medicine preparations. Space experiments with silkworms became possible with use of AD. These experiments used mulberry silkworm as high effective board test organism with outstanding developmental, reproductive and transgenic properties having impor­tant significance in future of cosmonautics. Introduction to practice of bioprotective and ecologically pure method of drying and sterilizing of green cocoons and by-products of silk manufacture allows to increase efficiency of cocoons reeling technology as well as to preserve nativity of biological active substances in mulberry silkworm pupae that is unachievable by traditional methods of raw material processing. New spheres of application of two important silk proteins - fibroin and sericin in medicine, cosmetics, for bio- and nanotechnology are opening with use of biotechnological approaches. At present the achievements and experience of R & D in these fields are used in creation of modern pests biocontrol agents. Schemes of efficient processing of cocoon raw material, by-products and wastes of sericulture and cocoon processing are devel- Institute of Physiology and Biophysics, Uzbek Academy of Sciences, I, Niyazov street, 700095, Tashkent, Uzbekistan. oped for obtaining of traditional and new consumer products.

  • Miller Fisher syndrome is characterized by ophthalmoplegia, ataxia and areflexia and develops after respiratory tract viral infection. Other events are GI tract infection, vaccination, digitalis intoxication, insect bite and delivery. Diagnosis of Miller Fisher syndrome can be made with clinical history taking, cardinal symptoms and normal findings of CT or MRI. We have experienced a case of Miller Fisher syndrome and treated with herbal medicine, eletro-acupuncture at paralytic external ophthalmic muscles. We enforced electro-acupuncture for 10 minutes daily. We used the PG-306 electro-acupuncture products(Suzuki Iryoki Co. Japan) and applied the low consequence wave of 1-8Hz. In 3 months, all the main symptoms disappered and the patient improved in health. Based on this experience, herbal medicine and eletro-acupuncture can be applied to the Miller Fisher syndrome.

  • To investigate the actual condition of orchard and pest management of persimmon orchards, a questionnaire was ask to the farmers in major cultivated areas of persimmon and dried persimmon, Sangju, Gyeongbuk in 2007 and 2008. 91.1% of persimmon farmers was over fifties in age and 94.7% of persimmon farmers was cultivated 'Sangjudungshi'. The greatest limiting factor for persimmon production was thought to be disease by the 58.4% of persimmon farmers and the most serious disease was anthracnose by Colletotrichum gloeosporioides. 60.2% of them was answered that the most serious insect pest was scale insects. Obtaining of knowledge or information on pest management depended own experience (37.2%) and 48.7% of answered farmers was decision-marking of pesticides depending on agrochemical market. 54% of persimmon farmers was applied pesticides $3{\sim}5$ times per year. Just 17.7% of them recorded the diary of pesticide application. The greatest problem for management of pest in persimmon orchard was lack of knowledge of pest (60.2%) and farmers considered increasing cost for pest management as the greatest problem with 52.2% in proportion. 66.4% of farmers was mixed cultivation with soybean (37.7%) and hot pepper (26.1%) in persimmon orchard. 44.2% among answered farmers mixed cultivation of persimmon with production of dried persimmon and 54.5% of farmers considered lack of labor as the greatest problem in production of dried persimmon.

  • A bacterial community analysis of the gut of Tenebrio molitor larvae was performed using pyrosequencing of the 16S rRNA gene. A predominance of genus Spiroplasma species in phylum Tenericutes was observed in the gut samples, but there was variation found in the community composition between T. molitor individuals. The gut bacteria community structure was not significantly affected by the presence of antibiotics or by the exposure of T. molitor larvae to a highly diverse soil bacteria community. A negative relationship was identified between bacterial diversity and ampicillin concentration; however, no negative relationship was identified with the addition of kanamycin. Ampicillin treatment resulted in a reduction in the bacterial community size, estimated using the 16S rRNA gene copy number. A detailed phylogenetic analysis indicated that the Spiroplasma-associated sequences originating from the T. molitor larvae were distinct from previously identified Spiroplasma type species, implying the presence of novel Spiroplasma species. Some Spiroplasma species are known to be insect pathogens; however, the T. molitor larvae did not experience any harmful effects arising from the presence of Spiroplasma species, indicating that Spiroplasma in the gut of T. molitor larvae do not act as a pathogen to the host. A comparison with the bacterial communities found in other insects (Apis and Solenopsis) showed that the Spiroplasma species found in this study were specific to T. molitor.

  • To elucidate the role of tow environmental factors, temperatures and photoperiod, in diapause induction and development of the dark grey cutworm, Agrotis tokionis B., field and laboratory experiments were implemented. As larvae entered diapause later, the diapause duration became shorter resulting in the synchronization of pupation of the test population. The summer diapause of this insect was assumed to be obligatory because every mature larvae had to experience summer dormant period at all experimental conditions of temperature and photoperiod. It was suggested that the diapause stage could be divided into two different phases in relation to temperature reaction. as the temperatures examined, the duration of diapause was shortened by higher temperature in the early phase, while it was shortened by lower temperature in the late phase. Th diapause period was the shortest under short-day condition (LD 8:16)

  • The Korea Water Resources Corporation(KOWACO) proposed bidding for an alternative design for Hwabuk Multi-purpose Dam in March of 2004. The site is located in Hakseong-ri, Goro-myeon, Gunwi-gun, Gyeongsangbuk-do and has adrainage area of $87.52km^2$. The purpose of this project is to establish an environmentally friendly plan for minimizing the damage that was caused by the construction of the Hwabuk Multi-purpose Dam. The design principle of KOWACO was the restoration of the natural environment, a harmonious landscape, and the creation of a space of regional and local culture. The basic concept of this project involves an ecological-restoration axis and a functional-connection axis. The site is divided into four spaces: (1) the space of memory and symbol, (2) the space of nature and ecology, (3) the space of regional and local culture, and (4) the space of the regional economy. There are four sub-spaces in the space of memory and symbol: the track forest, the time forest, the memory room, and the sun plaza. There are three sub-spaces in the space of nature and ecology: the habitat of aquatic birds, the wind forest, and the eco-corridor. There are five themed parks in the space of regional and local culture: the culture and relic room, the wildflower garden, the ecological pond, the insect observation park, and the pyogo maze. There are three areas in the space of the regional economy: the forest pension, the waterside pension, and the community center, as Dungdungi village was reorganized to serve as a lodging complex. These themed parks, working together, can offer an effective space for nature, culture, rest, and experience.

  • To investigate the actual condition of production and management of sod, a questionnaire was ask to 57 farmers in major cultivated areas of turf sod in Korea in 2010 and 2011. The results of the turfgrass management situation analysis showed a mixed farming where the ratio of the principal work and the side work progress similarly, and for the landholding type depending on the management scale, the rental ratio was high for a scale over 0.5 ha. Sod production farmers has high-profile in new varieties of turfgrass, integrated management of the fertilization and soil or disease and insect pest however the future of the turfgrass industry does not seem optimistic due to the problems such as market stability or scarcity of worker. Obtaining of information on culture methods depended neighbor's experience (81.8%). Concerning the varieties preference analysis, the 32.1% of farmer answered that the reproductive rate was a key factor for the new variety. Sod production farmers want to receive financial support (28.1%), improvement of distribution structure of sod (26.6%), and spread of good variety turfgrass (23.4%).

  • As a series of studies to develop pest management system for sweet persimmon production matched with the quarantine criterion of sweet persimmon-imported county, a survey was conducted by questionnaire on pest management practice and scheme of increasing income in sweet persimmon farms in Korea. Above 80% of sweet persimmon farmers was over fifties in age. The greatest limiting factor for sweet persimmon production was thought to be disease by the farmers. Percentage of farmers who answered that the most important pest is anthracnose cause by Gloeosporium kaki, and stink bugs was 64.6% and 73.5%, respectively. In particular, the farmers did not consider Dichocrocis punctiferalis, a main targer insect for quarantine in USA, as serious problem. Obtaining information on pest management practice or decision-making on both selection of pesticide and time of pesticide application depended highly on their own experience with the highest proportion. Eight to nine times of pesticide applications a year was highest among farms with 56.6%. More than 80% of farmers recorded the diary of pesticide application. farmers considered increasing cost for pest management as the greatest problem with 35.4% in proportion, and 34.5% of farmers pointed out that increase in export is essential for increasing farm income with highest proportion.
