From April 2010 to the present, seasonal occurrence of Riptortus pedestris was investigated. Five locations for population density and migration route tracking were the same as last year (two sites of Mt. Yangseong, Jujung-dong, O-Chang, and the campus of Chungbuk National University(CBNU)). In Mt. Yangseong, separated the farmland (80m) and forest (200 and 300m) by altitude, population density in 2010 was showed high density at mid-June, mid-Aug., and late-Oct., but population density in 2011 was showed high density at late-April, late-July and mid-Aug. In O-Chang and Jujung-dong, population density in 2010 was captured the adult from June to Aug. in the farmland, and from Sept. to Nov. in the forest. Total captured number of R. pedestris were high in farmland than forest. In campus of CBNU, the adult was captured from mid-Jul. to late-Aug. It showed the difference in the population density by its environmental conditions. Attraction effect of pheromone lure trap with soybeans were good than that of pheromone lure trap only. To track the migration of R. pedestris, we painted the fluorescent paint with different color. Being painted 500 R. pedestris were released and recaptured 10 and 20 days after release. Among released 500 R. pedestris at asl 300m on Yangseong site A and B in 25 Apr. were recaptured one at 300 and 80 m at site A, and site B was recaptured one marked R. pedestris adult at 200 m. In 25 May, release at 200 m in site A was recaptured only 80 m with 2 and site B was recaptured 200m with 8 and 80m with 1. Released in 17 Jul. at 80 m, marked R. pedestris adults were recaptured only 80 m with 5 and 2, respectively. It means that R. pedestris adults seem to migrate from the forest to the farmland in this season, but the data from Aug. to Oct. in 2010 was different.
