Uzi fly (Exorista bombycis Louis) is one of the major larval endo-parasitoid of silkworm (Bombyx mori). It causes extensive damage to sericulture industry. The application of synthetic organic pesticides has tremendous impact on minimizing pest population but their overuse and frequent misuse and high sensitivity towards the silkworms, has forced the entomologists to search for alternatives to chemical control, which is safe to silkworm, environment and farm workers. Biological control continues to offer exciting possibilities for the control of fly pest population. It is environmentally safe alternative to chemical control and offering a long-term protection. Several potential hymenopteran parasitoids have been screened. Among successful natural enemies, Nesolynx thymus, Trichomalopsis apanteloctena, Trichopria sp., Brachymeria lasus, Pediobius sp., Spalangia sp., Spilomicrus karnatakensis and Dhirhinus sp. are important. It is essential to predict accurately the efficacy of these natural enemies in a new habitat prior to its introduction. The important desirable attributes of these potential parasitoids viz., host searching capacity, specificity, power of increase and fitness and adaptability of the parasitoid in new environment has been recorded. Results of the host parasitoid interaction indicate that the aging of the host function as a factor that influence the host finding efficiency of the parasitoid. It is highly scored with 15-20 hrs old pupa of the host. However, aging of the parasitoid does not significantly affect it. The sex ratio is female biased which is advantageous from biological control point of view, Biological suppression methods involving conservation and utilization of natural enemies have been discussed in detail.

최근 국가적으로 환경정보들을 DB화하고, 체계화하며 통합하고자 하는 움직임이 활발히 전개되고 있는 있다. 이러한 노력은 특히 도시 및 지역차원에서 수립하는 법정계획인 환경보전계획의 공간계획화를 더욱 용이하게 하며, 이는 공간의 관리방향을 보다 명확하게 함으로써 토지의 보전은 물론 이용과 관련된 각종 계획들 간의 상충을 합리적으로 조정하도록 합의하는데 용이한 수단이 될 것으로 보인다. 이에 본 연구는 환경보전계획의 공간계획화를 위한 방안을 모색하였으며, 특히 환경요소 중 가장 민감한 자원으로 인식되는 생태환경을 중심으로 한 공간환경계획 수립방안을 제시하였다. 공간환경 계획 수립방안은 계획과정을 고려해 크게 1)기본방향, 2)공간정보의 수집, 3)공간환경현황 작성, 4)공간환경 관리계획 수립으로 구분하였으며, 특히 현황파악 및 계획수립 시 필요한 공간정보는 기존에 구축된 공간정보들을 최대한 활용할 수 있도록 국가나 지자체 차원에서 구축된 공간정보들을 목록화 하였다. 계획수립 시 고려되는 현황도는 토지이용(토지피복)과 자연생태 우수자원/지역 현황 작성방안을 제시하였으며, 이를 기반으로 광역생태축 계획과 보전, 복원지역 계획을 수립함으로써 생태환경을 고려한 환경보전계획의 공간화를 모색하였다. 기존연구 및 사례들을 통해 마련한 현황 및 계획방안은 경기도 지역에 적용해 봄으로써 그 활용가능성을 살펴볼 수 있었다. 이러한 계획은 관련 공간개발계획 수립 시 생태적 가치와 중요도를 고려한 계획안 마련에 기여함은 물론, 지역 내 개발사업 추진 시 계획의 적정성과 입지의 타당성을 검토하는 기초자료와 근거자료로 활용될 수 있을 것으로 보인다.

In order to identify key nations and bird species of conservation concern we described multinational collaborations as defined using network analysis linked by birds that are found in all nations in the network. We used network analysis to assess the patterns in bird occurrence for 10,422 bird inventories from 244 countries and territories. Nations that are important in multinational collaborations for bird conservation were assessed using the centrality measures, closeness and betweenness centrality. Countries important for the multinational collaboration of bird conservation were examined based on their centrality measures, which included closeness and betweenness centralities. Comparatively, the co-occurrence network was divided into four groups that reveal different biogeographical structures. A group with higher closeness centrality included countries in southern Africa and had the potential to affect species in many other countries. Birds in countries in Asia, Australia and the South Pacific that are important to the cohesiveness of the global network had a higher score of betweenness centrality. Countries that had higher numbers of bird species and more extensively distributed bird species had higher centrality scores; in these countries, birds may act as excellent indicators of trends in the co-occurrence bird network. For effective bird conservation in the world, much stronger coordination among countries is required. Bird co-occurrence patterns can provide a suitable and powerful framework for understanding the complexity of co-occurrence patterns and consequences for multinational collaborations on bird conservation.

관광단지 개발사업은 자연환경이 양호하고 경관이 우수한 지역을 대상으로 추진됨에 따라 주변 지역에 대한 환경부하를 지나치게 가중하는 점이 문제로 제시된 바 있다. 이에 본 연구에서는 2012년~2021년간 이루어진 국내 관광단지 개발사업의 환경영향평가 결과를 토대로 동 사업으로 야기되는 환경영향을 파악하였다. 특히 다양한 환경영향을 종합적·정량적으로 분석하고자 선행연구를 통해 마련된 EA-INDEX를 관광단지의 사업 특성에 적합하게 신규 도출하였으며, 이를 통해 관광단지 개발사업의 환경영향을 크게 자연환경 보전, 자원 보존, 생활환경 보호 부문으로 구분하여 각 세부 지표별로 살펴보았다. 그 결과 지난 10년간 국내 관광단지 개발사업은 친환경성이 증가하는 방향으로 추진·개발된 것으로 나타났으며, 특히 자연환경 보전 부문에서 그 증가 추세가 뚜렷함이 확인되었다. 반면 자원 보존 부문의 경우 친환경성이 감소하는 것으로 확인되었으므로 추후 신규 개발계획 수립 시 이를 제고할 수 있는 노력하는 것이 필요할 것으로 판단된다. 본 연구는 비교적 장기간에 걸친 관광단지 개발사업에 대한 환경적 영향을 파악하고, 특히 개발사업의 친환경성에 대해 각 세부 부문별 영향을 정량적으로 분석한 것에 의의가 있는 것으로 판단된다. 추후 개발사업과 관련한 정책 이벤트, 연관 사회적 이슈 등의 정보를 종합한 분석이 이뤄진다면, EA-INDEX를 활용한 개발사업의 경향 파악에 더욱 폭넓은 해설이 가능할 것으로 기대된다.

The purpose of this research is to analyze the contents related to environmental education(EE) in the elementary school textbooks for the following areas: well-balanced EE, and development of EE curriculum/teachers' guide in elementary school level. For the purpose of this analysis, elementary school teachers, education administrators and EE specialists were involved. Eleven content areas of EE, namely: natural environment, artificial environment, population, industrialization, natural resources, pollution, environmental conservation, environment sanitation, environment ethics, environmentally sound and sustainable development(ESSD), and daily li(e as a consumer, were analyzed. The results of the analysis are as follows: 1. There are total 1,140 contents related to EE in the elementary school textbooks of 7th Korea National Curriculum. 2. The textbooks of grade 6 contain the most number of EE contents, while the least number is in the textbooks of grade 3. 3. The subject that includes EE contents equally in its textbooks is social studies, and the subjects that relate a lot to EE are Korean language, science, and social studies respectively. 4. The content areas that are included a lot in textbooks are' natural environment', 'pollution', and' environmental conservation' respectively, while the contents of 'population','industrialization', 'ESSD' are included to a lesser degree. The content area most frequently mentioned in the textbooks is 'pollution', and the number of the contents are increasing along with the grade level. 5. Generally, the content areas of 'population', 'industrialization', and 'natural resources' are reflected in the textbooks to a lesser degree than others. 'Industrialization' is not included in the textbooks of grade 2, while 'population' is not included in ones of grade 4. According to the result, more concern about balanced EE in content areas is needed at the elementary school level. Similar studies tot K and secondary school levels are needed. The developmental study of EE guide book and teacher training for teaching EE using the book are also recommended.

Nepal is rich country in terms of its vast array of biological diversity. The relationship between local communities and the biological diversity in Nepal is a very entangle one, whereby two-thirds of our population are heavily dependent upon the biodiversity for their survival. The destruction of biodiversity signifies the destruction of people's livelihoods and survival. Biodiversity and genetic resources conservation has been a most significant part of the Nepalese society due to its socio-economic and cultural importance and provides the human race trees for timber, fuel, food, industrial raw materials, pharmaceuticals, beverages and environmental stabilization. Threats to biodiversity at global level is of greater concern, specially, human activities are the greatest factor currently affecting biodiversity, through the use of natural resources by industry, agriculture, hunting, and energy generation.

Recent conditions in North Sulawesi Province (NSP) have become favorable for the development of tourism. In this paper, we present the recent status of biodiversity and tourism in NSP as a basic consideration towards integrative biodiversity conservation strategy. Overall, biological accounts suggest that NSP is important for the world biodiversity conservation program. NSP's biodiversity makes the area a major nature-based tourism (ecotourism) site in the world. Development of diverse tourism programs in NSP has provided new opportunities for balancing development and conservation of regional ecosystems. However, the excessive tourism growth in some particular areas in NSP has been identified as the primary factor of environmental degradation. Nowadays, biodiversity of North Sulawesi regions are suffering from the number of tourist impacts and facilities. Based on those conditions, tourism planning and development in NSP is needed to formulate a proper strategy to protect the ecosystem and biodiversity from degradation and extinction. This will be a new challenge of sustainable island tourism development and biodiversity conservation in NSP.
