Abstract

An insect pest-controlling apparatus (1) includes a light-reflecting attraction unit (4) that reflects sunlight and a trap (6) to trap insects attracted to light reflected by the light-reflecting attraction unit (4). The light-reflecting attraction unit (4) is a reflector whose reflectance of 220 to 390 nm light wavelength components is 5% or less. Because the light-reflecting attraction unit (4) reflects almost no ultraviolet rays, the contrast of ultraviolet rays is increased in the space compared with sunlight by the insect pest-controlling apparatus (1) and diurnal agricultural insect pests are strongly attracted to the light-reflecting attraction unit (4). Accordingly, diurnal agricultural insect pests can be attracted and trapped in large quantities in the daytime.

Claims

1. An insect pest-controlling apparatus having a light-reflecting attraction unit that reflects sunlight and a trap that traps insects attracted by the light reflected by the light-reflecting attraction unit, wherein

the light-reflecting attraction unit comprises a reflector whose reflectance of light wavelength components of 220 to 390 nm is 5% or less.

2. The insect pest-controlling apparatus according to claim 1, wherein the light-reflecting attraction unit is further the reflector whose transmittance near a transmittance peak wavelength of the light wavelength components of 380 to 600 nm is 10% or more.

3. The insect pest-controlling apparatus according to claim 2, further comprising an odor generation unit that generates an odor to attract the insects, wherein

the odor generation unit uses an aqueous solution containing at least one of green leaf alcohol and green leaf aldehyde as an odor source.

4. The insect pest-controlling apparatus according to claim 1, further comprising an odor generation unit that generates an odor to attract the insects, wherein

the odor generation unit uses an aqueous solution containing at least one of green leaf alcohol and green leaf aldehyde as an odor source.

5. The insect pest-controlling apparatus according to claim 1, further comprising a light irradiation unit that emits the light to attract the insects, wherein

the light irradiation unit emits the light of at least a region of a wavelength range of 250 to 330 nm.

6. The insect pest-controlling apparatus according to claim 5, wherein the light irradiation unit is controlled so that a total quantity of the light in the wavelength range of 250 to 330 nm on an emission surface is 100 μ

W/cm² or more.

7. The insect pest-controlling apparatus according to claim 6, further comprising a filter, wherein

the filter is configured so that the light wavelength components of 340 to 380 nm of the light emitted from the light irradiation unit are not transmitted.

8. The insect pest-controlling apparatus according to claim 5, further comprising a filter, wherein

the filter is configured so that the light wavelength components of 340 to 380 nm of the light emitted from the light irradiation unit are not transmitted.

9. An insect pest-controlling apparatus having a light irradiation unit that emits light to attract insects and a trap that traps the insects attracted by the light emitted from the light irradiation unit, wherein

the light irradiation unit emits the light of at least a region of a wavelength range of 250 to 330 nm.

10. The insect pest-controlling apparatus according to claim 9, further comprising an odor generation unit that generates an odor to attract the insects, wherein

the odor generation unit uses an aqueous solution containing at least one of green leaf alcohol and green leaf aldehyde as an odor source.
