This study was conducted to determine the occurrence and route tracking of Riptortus clavatus from 5th April to 10th November, 2010. Investigation area was selected: farmland at Chungbuk National University (CBNU), Jujung-dong (Cheongju) and O-Chang (Cheongwon) that distinguished the farmland and the fores, and two sites by an altitude at Mt. Yangseong (Munui-myeon, Cheongwon). Aggression pheromone trap (below trap) and trap+soybean are set on two sites by an altitude of Mt. Yangseong farmland (80m) and forest (200 and 300 m). Population density of Riptortus pedestris showed the highest in Mid-Jun., Mid-Aug, and Late-Oct., and caught more trap+soybean than trap. Two sites of O-Chang and Jujung, R. pedestris was more caught to a farmland in June to August, but caught to forest at Sept. Comparison between traps, trap+soybean is more caught than trap, higher caught in season to a farmland from Jun. to Aug., a forest from Sept. to Nov. Farmland of CBNU without forest was caught from Mid-Jul. to Late-Aug, and the number of caught insect was higher in trap+soybean. This pattern caught more in trap+soybean shows the similar result from five investigation area but showed the difference according to the investigation area. R. pedestris was released after marked with florescent paint for route tracking. Ten days after release of 500 density at 200 m altitude (25th Aug), R. pedestris was re-caught seven in the same altitude, but the release at 80 m altitude (4th Oct.), R. pedestris was re-caught at 200 and 300 m. This result suggest that R. pedestris did not move in August to other altitude because of rich-food, however, R. pedestris seems to move in Oct. to the forest by reason of food-shortage or overwintering.
