In order to accumulate the ecological information of Drosophila suzukii for export negotiations of domestic strawberry, we weekly monitored occurrence of D. suzukii at three strawberry fields located in Gok-seong, Dam-yang and Hwa-sun using the best combination of trap and attractant from November 2017 to May 2018, the period of strawberry production. Monitoring was carried out at three sites (a hill located 150 meter distant to greenhouse, outside greenhouse and inside greenhouse) in Gok-seong. Drosophil suzukii was trapped at three short periods from November to the beginning of December, from the end of December to the beginning of January, and from April in a hill. At outside greenhouse, D. suzukii was trapped at two short periods from November to the early December and the beginning of May. In inside greenhouse, it occurred once after May 24th. Gok-seong data can be summarized as more occurrence for longer period as the distance to greenhouse increases. Dam-yang occurred once in a short period inside greenhouse and hill, respectively on May. In case of Hwa-sun, D. suzukii did not trapped in whole trapping sites during trapping period, except for the surrounding grape and peach cultivation areas at the end of November. Summarized, no occurrence periods are from November 20th, 2017 to May 14th, 2018 inside greenhouse; from December 11th, 2017 to May 3rd, 2018 outside greenhouse; and from January 8th, 2018 to April 12th, 2018 on a hill. In connection with strawberry culture, the D. suzukii tends to occur at the beginning and the end of the strawberry production period. We expect this result can serve as a helpful data for export negotiation for quarantine.
