Abstract

This study aimed to provide information on the biodiversity of various arthropods living in paddy fields during the winter season by examining their incidence density. Insect collection was carried out by 50 × 50 cm grids of soil surface and plants from paddy fields, as well as from ridges between paddies, using a battery-powered aspirator. The total number of individuals collected from paddy fields and inter-paddy ridges was 41,197, most of belonged to the orders Collembola, Hemiptera, and Diptera. Arthropods showed similar appearance patterns in fields under both organic and conventional farming. However, a higher number of insects was collected in organic farms. The species diversity, species richness, and species evenness were all greater in inter-paddy ridges than in paddy fields, in a statistically significant manner (P < 0.05).

월동기 논과 논두렁에서 서식하고 있는 다양한 절지동물의 발생밀도를 조사하여 생물다양성에 대한 정보를 제공하고자 본 연구를 수행하였다. 동력흡충기를 이용하여 논과 논두렁에서 각각 5지점씩 50×50 cm 격자 내에 있는 지표면과 식물을 흡입하여 채집하였다. 논과 논두렁에서 채집한 총개체수는 41,197개체였으며, 대부분 Collembola, Hemiptera, Diptera가 많이 채집되었다. 영농형태별 유기농법 재배지와 관행농법 재배지에서의 절지동물 출현패턴은 거의 유사하였으나 채집된 개체수는 유기농법 재배지에서 더 많았다. 종다양성지수, 종풍부도지수, 종균일도 지수는 논보다는 논두렁에서 모두 높게 나타났고, 시기별로 큰 차이를 보였는데 이는 통계적으로 유의하였다(P < 0.05).
