PROBLEM TO BE SOLVED: To provide a destructive insect-controlling device thereby diurnal agriculturally destructive insects can thereby be attracted and trapped in large numbers during the day in which the insects are activated.SOLUTION: A destructive insect-controlling device 1 is provided with a light-reflecting attractant part 4 that reflects sunlight, and a trap 6 for trapping the insects that are drawn to the light reflected by the light-reflecting attractant part 4. The light-reflecting attractant part 4 is a reflecting plate that causes reflectance of 220-390 nm light wavelength components to be 5% or less. Because the light-reflecting attractant part 4 reflects almost no ultraviolet rays, the contrast of ultraviolet rays in the space is increased compared to sunlight by the destructive insect-controlling device 1 and diurnal agriculturally destructive insects are strongly attracted to the light-reflecting attractant part 4. Diurnal agriculturally destructive insects can thereby be attracted and trapped in large numbers during the day.COPYRIGHT: (C)2010,JPO&INPIT【課題】害虫防除装置において、活動が活発な日中に昼行性農業害虫を大量に誘引して捕獲することができる。【解決手段】害虫防除装置1は、太陽光を反射する光反射誘引部4と、光反射誘引部4に反射される光により誘引された虫を捕獲するための捕獲部6と、を備える。光反射誘引部4は、220~390nmの光波長成分の反射率を5%以下とする反射板である。害虫防除装置1は、光反射誘引部4が紫外線をほとんど反射しないので、太陽光と比較して空間における紫外線のコントラストが高くなり、昼行性農業害虫が光反射誘引部4に強く誘引されるために、日中に昼行性農業害虫を大量に誘引して捕獲することができる。【選択図】図1
