摘　　要：为了有效地控制舞毒蛾Lymantria dispar的危害及保护自然天敌,研究了利用单一波长的太阳能灯诱捕舞毒蛾的方法。采用林间放置320 nm至585 nm不同波长的太阳能灯、不同颜色诱捕容器、长波与短波灯不同距离组合、太阳能灯与频振式杀虫灯对非靶标昆虫诱虫效果的比较等方法,确定灯光诱捕舞毒蛾的最佳技术。结果表明,340 nm太阳能灯诱捕舞毒蛾总量和雄虫量最大,且显著大于对照灯的相应诱捕量;380 nm太阳能灯诱捕雌虫量最大。诱捕舞毒蛾的最适时间为19∶30—21∶30。银色容器诱捕到的舞毒蛾最多。长波灯与短波灯相距50 m时,短波(340 nm)诱虫灯的诱捕量最大,且显著大于其他距离和短波对照灯的诱捕量,在此距离条件下,长波(520 nm)诱虫灯的诱捕量最小。单一波长的太阳能灯对非靶标昆虫的杀灭作用显著小于频振式杀虫灯。340nm太阳能灯可作为诱捕舞毒蛾的首选灯具,通过与筛选出的最适时间、敏感容器颜色和距离组合,能够在林间达到较好的诱捕效果。还可以通过长短波长的组合,在港口提供长波照明和短波诱虫,实现既减少舞毒蛾成虫和卵块随船迁移又兼顾亮化的双重目的。With the purpose of controlling the harm of Lymantria dispar and protecting its natural ene- mies, the methods of trapping L. Dispar adults with the single wavelength solar lamps were studied. In the study. The methods such as placing solar lamps with different light wavelength （change from 320 nm to 585 nm） in forest, using trap containers with different colors, combining long-wavelength with short-wavelength solar lamps at different distances and comparing the trapping effects of non-target in- sects by solar lamps with that by frequency trembler grid lamps were tested to find the better technology of light trapping method for L. dispar. The results showed the number of total L. dispar adults and male adults trapped by 340 nm solar lamp was the largest, which was significantly more than that of the con- trol. The number of the female L. dispar adults trapped by 380 nm solar lamp was the largest. The best time for trapping was 19： 30-21：30. The silver container displayed the best trapping effect for L. dispar adults. When the distance between long-wavelength lamp and short-wavelength solar lamp was 50 m, the short-wavelength （340 nm） solar lamp trapped the largest number of L. dispar, which was signifi- cantly higher than that of the others and the control. At the 50 m distance, the long-wavelength （520 nm） solar lamp trapped the least number of L. dispar adults. The killing effects of the single wave solar lamps on non-target insects were significantly lower than that of frequency trembler grid lamps. The 340 nm solar lamp with the best time, suitable container color and the best distance between long-wave- length lamps and short-wavelength solar lamps was a better choice for trapping L. dispar and could a- chieve better control effect in forest. Besides, by using long-wavelength solar lamps for lighting and short-wavelength solar lamps for trapping pests in harbor, the numbers of L. dispar adult and egg mass migrated with ships could be reduced and a better lighting effect could be achieved.
