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.
