This study was conducted to compare the community structure and biodiversity of epigeic spiders between pear fields cultivated by integrated pest management (IPM) and organic methods. This is the first study of this kind to be conducted in Korea. Eighty-four spider species from 22 families were identified among the collected 2,489 arthropods, with 754 individuals being sampled from IPM fields and 1,735 individuals from organic fields. Generally, Theridiidae, Linyphiidae, Lycosidae, Agelenidae, Gnaphosidae, and Salticidae were the dominant spider families in the pear orchard regardless of the farming methods, and species richness and abundance were higher in organic fields than in IPM fields. The dominant species were the wolf spiders (Lycosidae) and stone spiders (Gnaphosidae), and their cumulative abundance was 70.7% in IPM fields and 72.7% in organic fields. The community structure between organic and IPM fields was heterogeneous, with a 45% similarity level. Biodiversity, species richness, abundance, and species diversity index were higher in organic fields than in IPM fields, and significantly different between the farming methods. Seasonal fluctuations in biodiversity were similar in both IPM and organic fields. The species richness and species diversity index increased and the abundance decreased in the second half of the cultivation period. This study on the community structure and biodiversity of epigeic spiders, which form one of the most important predator groups, will provide principal ecological and faunistic information required to maintain the biodiversity of useful arthropods in agricultural ecosystems and help implement sustainable agriculture based on the active use of natural enemies.

Crop inputs in excess of the yield potential of the soil type reduce profitability and increase pollution problems from leaching and runoff. Inaccurate fertilizer and pesticide application can also result in profit loss. Current farming practices plan only for the dominate soil in the field. A government-supported program titled "Pilot village project for the environment-friendly agriculture" was proceeded from 1999 to 2001 to tackle the problems with which our agriculture is faced by introducing IPM, INM and others. The objective of this study is to consider the potential input savings of agricultural chemicals and economic feasibility of the project compared with the conventional farming. The results of the analysis indicate the followings: (1) organic or no-pesticide farming size was increased from 9% in 1999 to 20% in 2001 ; (2) crop yield was a link bit lower than that of the conventional farming, but the sal6 price, gross income and income of the pilot village were 6%, 10% and 9% higher than that of the conventional farming, respectively; and (3) fertilizer and pesticide use also showed decreasing trend gradually.

1950년대에 종합적 유해생물관리(IPM)의 개념이 발달하기 시작하여 1960년대에는 경제학적 개념이 해충방제에 포함되기 시작하였다. 1970년대부터 미국과 유럽을 중심으로 종합방제와 관련된 연구가 진행되었다. 우리나라 병해충 종합방제에 관한 연구는 1970년대 감귤해충에 대한 종합방제연구와 통일계 품종의 보급에 따른 수도해충종합방제연구에서 시작되었다. 우리나라 사과 병해충종합관리 연구는 1980년대 화학농약을 이용한 방제 및 약제 저항성 연구, 해충 및 천적생태에 대한 연구, 성페로몬에 대한 연구를 시작으로 진행되었다. 1990년대부터는 농가보급을 위한 IPM 연구사업과 현장실증사업이 병행되었다. 2000년대에는 교미교란제를 중심으로 한 해충예찰과 발생모형 개발, 해충에 대한 DB프로그램 및 정보공유를 위한 네트워크가 구축되었다. 2010년대는 무인예찰 및 자동화기술 개발을 통해 IPM 기술이 확장되고 있다.

본 연구는 임산물 가운데 생산과 수출 양면에서 가장 중요한 밤을 대상으로 환경과의 조화로 지속가능한 밤 생산을 실시하면서 소비자에 대한 밤의 안전성 확보는 물론 일반관행재배 밤과의 가격차별화를 통해 농가소득 증대에 기여할 수 있는 친환경 밤 생산 확대방안을 도출하는데 목적이 있다. 이를 위해 친환경 밤 생산농가의 실태 및 경영성과 분석을 실시하였다. 그 결과, 친환경 밤 생산은 아직 초기단계로서 생산기술의 미정립, 제초작업 및 병충해방제 등 관리적인 문제, 안정적인 판로의 미확보, 높은 생산비 등이 문제점으로 지적되었다. 따라서 이러한 문제들을 해결하여 친환경 밤 생산 확대를 유도하기 위해서는 민관(民官)협력 하에서 친환경 밤 생산기술 체계의 확립 및 보급, 친환경적인 토양관리(INM) 및 병충해종합관리시스템(IPM) 구축, 생산효율성을 향상 시킬 수 있는 친환경 밤 생산단지 조성, 일반관행 밤 생산에서 친환경 밤 생산으로 전환 할 경우 이로 인한 소득감소분을 보전할 수 있는 친환경직불제도입, 일반관행재배 생산농가 및 소비자에 대한 지속적인 친환경 밤의 홍보강화 등이 필요하다.

Citrus farming become one of highly potent area for the farmer s income in the Asia region. Because of its favorable taste and distinctive aroma, attractive color, and nutritional values, market demand has increased steadily along with the income increases in the region. However, realization of the potent have been constrained due to poor orchard management, frequent occurrences of pest and diseases, and a high cost in production besides of the market failures. Cutting down of production cost should be an operational goal to obtain mope profit where marketing structure has yet been underdeveloped. The objective of this study was to provide a comparative information to those program efforts of searching comparative advantage in production. For the three countries, reduction of labor cost by reduction of chemical application frequency was recommended while pursuing further mechanization in those operation such as in pruning, harvesting and pest control. Adoption of the IPM (integrated pest management) will be useful to reduce the number of spraying chemicals with changed knowledge and attitude of the farmers.
