| Outline of Final Research Achievements |
Effects of the surrounding landscape characteristecs on insect pest population in paddy fields were evaluated. From June to September of 2015 and 2016, abundance of the major pest species were estimated in 24 organic paddy fields of Kamikawa, Sorachi and Ishikari district. In landscape characteristics, Abundance of T. caelestialium was positively related with area of wheat fields. Abundance of Oulema oryzae was positively related with area of forest area. Potential natural enemies of these pest insects were also related with surrounding landscape use, but the landscape type and scale vary in species.
