摘　　要：为探索无公害防治杨毒蛾的方法，利用320～585 nm的单波长太阳能灯19盏开展林间诱杀研究。结果表明，365 nm太阳能灯对杨毒蛾总量和雄蛾诱杀量最大，368 nm太阳能灯对杨毒蛾雌蛾的诱杀量最大，以19：30-20：30时段诱杀效果最好。供试诱虫灯诱杀杨毒蛾总量的雌雄比2.1：1；18：30-19：30雌雄比最高，为7.5：1；21：30-22：30雌雄比最低，为0.7：1；4个时段诱杀杨毒蛾雌雄性比差异显著。蓝色容器的诱杀量较大，白色容器诱杀量较小；将装水容器放于距地面1.2 m高度比放在地面上对杨毒蛾有更好的诱杀效果。365 nm太阳能灯可作为诱杀杨毒蛾的最佳灯具，通过与筛选的最适时间、敏感容器颜色和容器高度组合，能够达到较好的诱杀效果。For exploring the nuisanceless means of controlling the harm of Stilpnotia candida,19 single-wavelength solar lamps with the wavelength being 320~585 nm were used in forest. The results showed that 365 nm solar lamp trapped the biggest numbers of to-tal S. candida adults and male S. candida adults and the 368 nm solar lamp trapped the biggest number of female S. candida adults. The best time interval for trapping S. candida adults is 19：30-20：30. The female-male ratio of S. candida adults trapped by total solar lamps was 2.1：1. During 18：30-19：30, the female-male ratio was 7.5：1 and reaches the biggest. During 21：30-22：30,the fe-male-male ratio was 0.7：1 and reaches the lowest. The female-male ratios of S. candida adults trapped during four time intervals were significantly different. The number of S. candida trapped by blue water containers was the biggest and by white water containers was the least. It could get better effect of trapping S. candida when the water container placed 1.2 meters higher than placed on the ground. The 365 nm solar lamp was a better choice for trapping S. candida and could achieve better control effect in forest when combined with the best time,the suitable container color and the suitable water container height.
