昆虫趋光行为及灯光诱杀技术

Insect Phototaxis Behavior and Light Trapping Technology

多种昆虫具有趋光习性,基此开发灯光诱杀技术进行害虫防治。我国诱虫灯装备发展经历了白炽灯、黑光灯、双波灯、频振式杀虫灯等阶段。但以上杀虫灯光谱范围较宽,选择性差,易杀伤天敌。随着半导体技术的进步,发光二极管(light-emitting diode,LED)相较传统光源具有多种优点:亮度较高、能源消耗少、波长范围窄等。LED灯作为诱虫光源可有效减少对天敌昆虫的误杀,成为目前最佳的诱虫光源。因此,LED诱虫灯在害虫防治中具有重要的应用前景。

Phototaxis is a common behavioral trait of many insect species and light trapping technology was developed based on this behavior.In China,pest light trapping technology and devices have undergone development stages as follows:incandescent lamp,black light lamp,two-wave-lamp,frequency trembler grid lamp.However,the above mentioned light traps have wide wavelength range,and not only can catch the targeted pest,but also the natural enemies.Recently developed light-emitting diode(LED)technology has advanced insect-vector traps and improved trap efficiency to the pest and reduced harmful effects to the natural enemies by using less energy and producing narrow spectral bands of light.Hence,LED lamp has a great potential for effective integration into the pest management programs.
