This study was conducted to compare the community structure and biodiversity of ground-dwelling invertebrates between conventional and organic paddy fields’s levees. Ground-dwelling invertebrates were collected using a pitfall trap every month for two years (2010-2011) in levees of conventional and organic paddy fields. The numbers of species and individuals were higher in organic paddy field than in conventional paddy field. For the pests, the treatment of insecticide and herbicide reduced the number of Delphacidae, and Chrysomelidae, but did not affect the other pests such as Chronomidae, Culicidae, Thripidae, and Aphididae. For the natural enemies, the treatment reduced the number of individuals of most of enemy's taxon (except only one taxonomic group, Ichneumonidae) in the levee of conventional paddy field.
