LED杀虫灯对温室害虫的诱杀效应

Study on the Trapping Effect of LED Insect-trapping Lamp on Greenhouse Pests

[目的]为防治温室害虫提供安全有效的杀虫手段。[方法]以高压电网和粘虫黄板为对照,研究自制LED灯板对温室害虫的诱杀效果。[结果]在4月20日和21日,强、中、弱光黄色LED杀虫灯的杀虫量分别为36、20、19和93、82、80头;其对射黄板的杀虫量分别为20、15、10和57、40、39头;无杀虫灯对射黄板的杀虫量分别为5和8头。光强越强,杀虫越多。LED杀虫灯的诱杀效果高于相应对射黄板,杀虫灯对射黄板的杀虫量高于无杀虫灯对射的黄板。在4月26日和27日,绿、蓝、黄、红杀虫灯的杀虫量分别为66、56、43、5和228、234、120、23头;绿色、蓝色LED杀虫灯杀虫最多,黄色杀虫灯次之,红色杀虫灯最少。[结论]LED杀虫灯适用于防治温室害虫。

[ Objective] The study aimed to provide safe and effective insecticidal means for controlling greenhouse pests. [ Method] With highvoltage electrified wire fence and yellow sticky board as CK, the trapping effect of self-made LED insect-trapping lamp-board on greenhouse pests was studied. [ Result] On Apr. 20th and 21st, the insects killed by intense, moderate and weak yellow LED insect-trapping lamp were 36, 20, 19 and 93, 82, 80 resp. ; the insects killed by the yellow sticky boards exposed to them were 20, 15, 10 and 57, 40, 39 resp. ; the insects of yellow sticky boards non-exposed to insect-trapping lamp were 5 and 8 resp. The more intense the light intensity was, the more the killed insects were. The trapping effect of LED insect-trapping lamp was higher than that of the corresponding yellow sticky boards exposed to them and the insects killed by yellow sticky board exposed to insect-trapping lamp were more than that killed by yellow sticky board non-exposed to insect-trapping lamp. On Apr. 26th and 27th, the insects killed by green, blue, yellow and red insect-trapping lamp were 66, 56, 43, 5 and 228,234, 120, 23; the insects killed by green and blue LED insect-trapping lamp were most, the insects killed by yellow insect-trapping lamp were secondary and the insects killed by red insect-trapping lamp were least. [ Conclusion] LED insect-trapping lamp was suitable for controlling greenhouse pests.
