This study was conducted to identify the seasonal occurrence patterns of peach pyralid moth, Dichocroscis punctiferalis (Guenee), and persimmon fruit moth, Satthmopoda masinissa Meyrick, in persimmon orchards in four different regions, Ulsan and Jinyeong in Gyeongsangbuk-do, and Naju and Yeongam in Jeollanam-do. Three pheromone traps (Delta trap, GreeAgro Tech) for each moth species were installed at each site and checked with 1 week intervals. Peach pyralid moth and persimmon fruit moth occurred in all four study sites. Two moth species exhibited two distinctive peaks, but there were some time differences in the peak among sites. Peach pyralid moth first occurred in late May to early June in Ulsan, Jinyeong and Naju but occurred in late July in Yeongam. Overall, the first peak appeared in mid- to late June but the time of the second peak varied widely among sites. Persimmon fruit moth first occurred in early to mid-June in Ulsan, Jinyeong and Naju but occurred in mid-May in Yeongam. The first peak appeared in mid- to late June in Ulsan, Jinyeong and Naju but it appeared in late May in Yeongam. The time of the second peak was around late August in the study sites except Ulsan where the second peak time was in late September.
