The occurrence and damage of stink bugs were monitored at South Korea from 2007 to 2008. A total of 11 stink bug species were observed in paddy field and occurrence periods of stink bugs were significantly differed by species. In occurrence period and damage of stink bug feeding in paddy field, Scotinophara lurida occurred from June, Cletus punctiger, Eysarcoris aeneus, Rhopalus maculatus, Riptortus clavatus, E. ventralis, Stenotus rubrovittatus occurred from August and Pachygrontha antennata, C. schmidti, Trigonotylus caelestialium, Paromius exiguus occurred from September. When we were classified into two region with mountain and plain area cultivated rice, generally C. puntiger population was higher in mountain area than plain area, and E. aeneus was higher in plain area than mountain area. Also, stink bug species were higher in environment condition formed with a paddy field and a waterway overgrown with weeds. Control threshold for E. aeneus in paddy field was 1-2 individuals/heading stage, and then rate of pecky rice made to 5.0% while milk stage, dough stage and yellow ripe stage made to less than 5.0%.
