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 comprising:

a light-reflecting attraction unit that reflects sunlight;

a trap that traps insects attracted by the light reflected by the light-reflecting attraction unit, the light-reflecting attraction unit comprising a reflector whose reflectance of light having wavelength components of 220 to 390 nm is 5% or less,

wherein the transmittance of the reflector near a transmittance peak wavelenght of light having wavelength components of 380 to 600 nm is 10% or more;

a light irradiation unit that emits light to attract the insects,

wherein the light emitted by the light irradiation unit is within at least a region of a wavelength ranging from 250 to 330 nm, and

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 of the light irradiation unit is 100 μ

W/cm ² or more; and

a filter,

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

2. 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.

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, wherein the trap traps the insects attracted by the light emitted from the light irradiation unit.

5. The insect pest-controlling apparatus according to claim 4, 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 the green leaf aldehyde as an odor source.

6. The insect pest-controlling apparatus according to claim 1, wherein the light-reflecting attraction unit is impregnated with an odor source that attracts insects.

7. The insect pest-controlling apparatus according to claim 1, wherein the filter is separate and distinct from the emission surface of the light irradiation unit, and wherein the filter is positioned between the light irradiation unit and light-reflecting attraction unit.
