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.

In this study, three types of synthetic fiber materials were evaluated, namely, DM20, SK78, and T147, to replace steel chains in shipbuilding and offshore fields with fiber chains as there is increasing demand for chains with lighter weights and improved usabilities. The strength and quasi-static stiffness were analyzed to select suitable yarns for the fiber chains. The durability of the yarn was evaluated by performing a 3-T (time to rupture) test as a specific tension level. The results of the experiment revealed excellent dynamic stiffness in DM20 and highest values of the windward and leeward stiffness in T147. 3-T linear design characteristic curves for a specific tension level were derived for the three types of fiber materials. The findings of this study can provide insights for improving strength and durability in fiber chain design.
