双光谱LED杀虫灯在新余蜜橘上的诱杀效果

Trapping and Killing Effect of Dual Spectrum Led Insecticidal Lamp on Xinyu Tangerine

2019年5月—2021年10月,在新余市汾阳果业柑橘基地开展新余蜜橘害虫的防治试验,使用双光谱LED太阳能杀虫灯,建立柑橘园绿色防控技术示范基地。结果表明,共诱杀柑橘主要害虫6目14科22种,以蛾类、金龟类和蝽类为主,其中斜纹夜蛾、吸果夜蛾、铜绿金龟、柑橘潜叶蛾、星天牛、麻皮蝽、茶翅蝽、柑橘小实蝇、爆皮虫、粉虱、橘实蕾瘿蚊较多,柑橘园虫口减退率最高达80.3%。而诱杀到的益虫蜻蜓、瓢虫、草蛉、寄生蜂数量较少,益害虫数比例小于1.08%,在一定程度上降低了杀虫灯对柑橘园生态的负面影响。灯下主要害虫的种类和数量呈季节性变化,与同期开展的柑橘园害虫调查结果对比,虫情发生期相一致,具有虫情预报功能。

From May 2019 to October 2021,the paper carried out the prevention and control of citrus pests in Xinyu Fenyang Fruit Industry Citrus Base in Xinyu City,and established a demonstration base for green prevention and control technology of citrus gardens with the use of dual-spectral LED solar insecticidal lamps.The test resulted show that the total of 6 orders,14 families and 22 species of citrus main pests were trapped and killed,with the main pests being moths,turtles and stinkbuys.Among them,leafworm,the moth,fruit noctuid moth,verdigris sawyer beetle,light green shield,hemp skin bugs,bugs,citrus tea wing small fruit fly,blasting,orange skin,whitefly bud gall midge were more common.Citrus orchard population decline rate up to 80.3%.However,the number of beneficial insects such as dragonflies,ladybugs,lacewings and parasitic wasps was small,and the proportion of beneficial pests was less than 1.08%.To a certain extent,the negative effects of insecticidal lamps on citrus orchards were reduced.The species and quantity of the main pests showed seasonal variations,and the occurrence period of pests was consistent with that of the citrus orchard pests survey conducted in the same period,which had the function of pest prediction.
