Athetis dissimilis (Hampson) (Lepidoptera: Noctuidae) [뒷흰날개담색밤나방] was attracted to pheromone traps for Euzophera batangesis (Lepidoprera Pyrimidae) [밤알락명나방], when occurrence of E. batangesis was monitored in sweet persimmon orchard with its pheromone, (Z)-9-tetradecenol (Z9-14OH), (Z9,E12)-9,12-teradecadienol (Z9,E12-14OH) and their mixture. With the components, we monitored the seasonal occurrence of A. dissimilis, tested response of the moth to single or mixed components, and compared efficacy of three different types of traps. A. dissimilis was trapped on May 14 for the first time. First occurrence peak was observed during June 4-24 and second peak during August 20 – September 10. A. dissimilis was attracted to single component of Z9-14OH and Z9,E12-14OH and to their mixture at Jinju, Sancheong, and Sacheon. In trap efficacy tests, delta traps with white color caught most number of the moths significantly at Sacheon. However, at Sancheong, there was no statistical difference among the traps, although funnel trap caught most number of A. dissimilis. Pest status of A. dissimilis is not known eg. whether it is a pest of persimmon or other fruits. However, with Z9-14OH, E9,E12-14OH and their mixture, it is expected to be monitored and controlled.
