The insect trap 1 includes a housing 3 whose front surface is opened and an attracting light source 4 as an attracting source for attracting the insect 2 from the opening 31 into the housing 3. Here, the housing 3 has a capture space 32 for capturing the insect 2. The insect trap 1 includes a suction unit 5 that sucks the insect 2 attracted by the attracting light source 4 into the capture space 32 and a disturbance light source 6 as a disturbance unit that disturbs the insect 2 sucked by the suction unit 5. .

  The housing 3 has a horizontally long box shape that can accommodate the above-described components, and is formed by, for example, sheet metal processing using a steel plate such as SUS material or aluminum material, or injection molding using acrylic resin or the like. The The capture space 32 is defined between the opening 31 and the suction portion 5, and an inlet 33 for sucking the insect 2 is disposed below the attracting light source 4. The outer edge of the entrance 33 is a substantially rectangular shape extending in the longitudinal direction of the attracting light source 4. The inlet 33 is not limited to the above-described configuration, and may have a laterally long oval outer edge, or may be formed by forming a plurality of holes in a plate-like member disposed in front of the capture space 32. May be. A part 34 of the partition wall forming the capture space 32 is detachable from the housing 3 so that the user can discharge the captured insect 2. The structure for discharging insects is not limited to the above, and the casing 3 may be provided with a window that can be opened and closed. A lower part in front of the housing 3 communicates with the capture space 32 and serves as an arrangement part 35 for attaching the suction part 5.

  The attracting light source 4 is a straight tube-shaped lamp that emits attracting light containing ultraviolet rays, and is provided horizontally above the disturbing light source 6. The ultraviolet rays contained in the attracting light are UV-A (wavelength: 315 to 380 nm) set based on the traveling curve or the visibility curve of the insects, and have a high attracting effect. Examples of the attracting light source 4 include a fluorescent lamp, a cold cathode lamp, a mercury lamp, and a xenon lamp. The attracting light source 4 is attached to sockets 7 disposed on both inner walls of the housing 3, and the socket 7 is connected to a terminal block 9 via a ballast 8. The terminal block 9 is connected to a commercial power source by a power line 10. A reflector 11 that reflects light from the light source forward is provided behind the attracting light source 4 so that the light from the attracting light source 4 is output through the opening 31 to the outside of the insect trap 1 without waste.

  The disturbing light source 6 is provided in the vicinity of the inlet 33 and irradiates the insect 2 attracted by the suction part 5 with attracting light from below to disturb the insect 2. Here, many of the insects 2 determine the sense of parallelism using light containing ultraviolet rays as a clue, and specifically, the direction of the light source that emits the light is determined as the upward (celestial) direction. Therefore, when the insect 2 is irradiated with intense attracting light from below, it is possible to take away the sense of balance of the insect 2 (the sense of direction of the top and bottom). The present invention makes use of such insect disrupting action.

  The disturbance light source 6 is composed of a narrow-angle light distribution type LED matrix in which a plurality of LEDs are combined, and the light distribution is adjusted so as to emit the attracting light upward. Therefore, the attracting light from the disturbing light source 6 does not leak to the outside of the insect trap 1, and the insect 2 around the insect trap 1 is not attracted to the disturbing light source 6. The spectral characteristics of the disturbing light source 6 are preferably those having a peak in the ultraviolet region where the wavelength is near 360 nm, and may include a white light region. The light from the disturbing light source 6 is set to have a higher luminance near the entrance 33 than the light from the attracting light source 4. The disturbing light source 6 is not limited to the above configuration, and may be a fluorescent lamp, a cold cathode lamp, a mercury lamp, a halogen lamp, or the like. The disturbance light source 6 is also connected to the terminal block 9 as described above.
