Five major migratory insect pest populations (Nilaparvata lugens, Sogatella furcifera, Laodelphax striatellus, Cnaphalocrocis medinalis, Mythimna separata) migrate from the southern China to Korea through jet streams. This study was conducted from July 2017 to August 2017 in rice paddy of Jeolla-province. C. medinalis and M. separata collected using pheromone traps, while N. lugens, S. furcifera and L. striatellus collected using 3 methods (visual surveys, sweeping surveys, sticky traps). Spatial Analysis by Distance IndicEs (SADIE) was used to analyze spatial distribution and index of aggregation Ia, index of clustering Vi, Vj were used to investigate the spatial distribution. Also, the clustering indices were mapped as red-blue plot.
