Since 2000, the damages of hemipteran pests have severely increased. This study was performed to find the proper monitoring methods and investigate seasonal occurrences of the two apple-infesting stink bug species by the year and to evaluate the orchard rate of infestation and rate of damaged apple. Also the preferences of stink bugs to the crabapple cultivars were investigated in orchards. Compared data obtained from monitoring methods using visible counts, aggregation pheromone traps or mercury light traps, the occurrence density of apple-infesting stink bugs (Plautia stali and Halyomorpha halys) could be monitored more effectively in aggregation pheromone trap than visible count or mercury light trap. The occurrence densities of two species during growing season were low in 2013, but increased in 2014. From the investigations at 25 orchards of eight districts was the infestation rate was at 16.7% in 2013 and 62.1% in 2014 . The occurrence density of stink bugs in crabapples was highest in ‘Purple lemoine’ followed by ‘Professor sprenger’ ‘M. baccata’, ‘Robinson crab’, ‘Sandong pingguo’, damaged fruit rate. The number of damaged holes was high in order as ‘Hopa-A’, ‘Sandong pingguo’, ‘Adam’s crab’, ‘Professor sprenger’, ‘Purple lemoine’.
