Insect pest-controlling apparatus
First Claim
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, andwherein 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.

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.
