PROBLEM TO BE SOLVED: To provide an anti-moth device for solving problems in which an anti-moth net has high effect in a no-fruit damage rate of 100% for suppressing damage of crops, but an installation cost is high and has to be removed in the typhoon, an anti-moth light has difficulty to irradiate all the crops with light and the no-fruit damage rate is around 60%, and the direction to oscillate acoustic wave in an ultrasonic wave oscillator cannot cover all directions of 360° and the no-fruit damage rate is around 65%.SOLUTION: An anti-moth device is an LED anti-moth light for emitting light in a range of 360° and the illuminance of a crop cultivation field emitted by the light is made 1 lux or more. Also, an ultrasonic wave oscillator for continuously emitting a sound wave toward the inside of the field is used together, and thereby the no-fruit damage rate becomes 90% or more.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】 作物の被害を抑制するため、防蛾ネットは無被害果率100%と効果は高いが、設置費用が高く、台風時には撤去しなければならない。防蛾灯は作物全てに光を照射することが難しく無被害果率は60%程度である。超音波発振器は音波を発振する方向が360°全方向に出すことができないため、無被害果率は65%程度である。【解決手段】 360°の範囲に光を放射するLED防蛾灯で光があたる農作物栽培圃場の照度を1ルクス以上にし、かつ前記圃場内部に向けて連続して音波を発する超音波発振器を併用することにより無被害果率は90%以上になった。【選択図】図1
