The black cutworm (Agrotis ipsilon) and sod webworm are the main lepidopteran pests that injure the turfgrasses of golf courses. This study was conducted using the sex pheromone trap to find out the seasonal phenology of the black cutworm and sod webworm in the golf course. The attracted number to the traps of the black cutworm and sod webworm varied by year, and there were also differences between regions. Overall, black cutworm occurrence peaked between late May to early June, late June to mid-July, and mid-August to mid-September. In addition, sod webworm showed peak occurrence from late June to early July, mid-July, and late September to mid-October. Black cutworms were more attracted to the cone trap than the delta trap. Black cutworm had a higher incidence of 2nd generation, and sod webworm had a large amount of 3rd generation. Effectively control the two pests on the golf course, it is thought that it is necessary to devise a management method through accurate monitoring.
