烟草夜蛾对太阳能诱虫灯和性诱剂趋向效果的比较研究

Study on Trapping Efficiency of Solar Trap Lamps and the Sex Pheromones to Helicoverpa assulta(Guenee)in Tobacco Fields

烟草夜蛾是烟草上的主要叶食性害虫之一。本研究在湖南省耒阳市烤烟大田生长期,应用太阳能诱虫灯与烟草夜蛾性诱剂诱芯对烟草夜蛾的诱集效果进行了对比研究,结果发现:太阳能诱虫灯和性诱剂诱芯对烟草夜蛾都有较好的诱集效果。同时发现,在单台太阳能诱虫灯的水盆上方添置烟草夜蛾诱芯时,诱捕到的烟草夜蛾数量明显多于单台不加诱芯的太阳能诱虫灯或单个使用诱芯的诱捕量的总量,但是,也明显少于两种诱捕器的总和。因此,对于烟草夜蛾,在诱虫灯上方加放同种性诱剂,虽然可以提高单灯诱虫效果,但是不如分开安装诱捕器二者诱蛾量的总和。所以,建议性诱与灯诱单独进行,不宜混合使用。

Tobacco budworm Helicoverpa assulta(Guenee)is one of the major tobacco leaf feeding pests in China.This study was conducted in Leiyang City,Hunan Province in tobacco growing stage.The trapping effects of solar trap lamp and tobacco budworm sex pheromone lure to tobacco budworm were evaluated.The results showed that solar trap lamp and sex pheromone lure of tobacco budworm have a good trapping effect.
