The present invention relates to a fruit fly-attracting trap device including a first casing having a body portion that has an open upper surface and a hollow structure, a base that is formed in a lower portion of an upper body portion, a coupling step portion that is formed at an upper end of the body portion, and a hook step that is formed to protrude from an inner circumferential edge of the coupling step portion； a second casing having a disk that is mounted on the hook step, a plurality of capturing pipes that are vertically coupled to penetrate the disk, a phosphorescent attracting member that is provided in the vicinity of upper ends of the capturing pipes, and reversal prevention tubes that are coupled with respective lower end portions of the capturing pipes； and the second casing having a hollow head portion that has an opening portion in a front surface and a neck portion that is integrally formed in a lower portion of the head portion, has an open lower portion, and is fastened to the coupling step portion, in which an attraction agent filling tank for liquid attraction agent filling is provided in the body portion of the first casing and the first and second casings have an animal shape when coupled with each other. The present invention has an outer shape resembling an animal character and thus fits harmoniously with surrounding environments. Also, fruit flies are attracted by using phototaxis at night and by the fruit fly attraction agent, and escape of the fruit flies attracted and captured is prevented from the beginning. In addition, the captured fruit flies can be easily removed and charging and discarding of the liquid attraction agent can be facilitated.본 발명은 초파리 유인 트랩장치에 관한 것으로, 상부면이 개방된 중공 구조인 몸체부와, 상부 몸체부의 하부에 형성된 받침대와, 상기 몸체부의 상단에 형성된 결합단부와, 상기 결합단부의 내주연에 돌출 형성된 걸림단을 갖는 제 1 케이싱과； 상기 걸림단에 거치된 원판과, 상기 원판에 관통되게 수직 결합된 복수 개의 포집관과, 상기 포집관의 상단 주변에 제공된 축광 유인부재와, 상기 포집관의 하단부와 각기 결합된 역행 방지튜브를 갖는 제 2 케이싱과； 전면에 개구부가 형성된 중공 구조의 머리부와, 상기 머리부의 하부에 일체로 형성되
