| 为提高现有诱捕器及灯光诱捕对美国白蛾Hyphantria cunea (Drury)的诱捕效果, 本研究对目前应用的6种美国白蛾诱捕器进行筛选, 以明确对美国白蛾诱捕效果最佳的诱捕器及LED波段; 同时对美国白蛾日节律进行了观察?结果显示, 桶形诱捕器对美国白蛾的诱捕效果最好, 平均每个7.1头, 显著高于其他诱捕器; 灯光诱捕美国白蛾成虫效果最好的波段为360~365 nm; 性信息素协同360~365 nm LED灯的诱捕效果显著高于其他两组; 美国白蛾昼伏夜出的特性明显, 试验结果表明该虫在凌晨02:00-04:00和晚上18:00-20:00的活跃度最高?本研究为性信息素诱捕器及LED灯在不同时间段进行美国白蛾监测与防治提供了技术支撑? |
| 英文摘要: |
| In order to improve the trapping efficiency of existing traps and light traps against Hyphantria cunea, this study screened six traps currently in use to identify the best trap and LED bands for trapping H.cunea. Meanwhile, the circadian rhythm of H. cunea was also observed. The results showed that the barrel trap is the best for H. cunea. Averagely 7.1 moths were caught per trap, significantly higher than by other traps. The band with the best trapping effect was 360-365 nm. The effect of sex pheromone combined with 360-365 nm tube was significantly higher than that of the other two groups. H. cunea had an obvious nocturnal habit. The experimental results indicated that the most dynamic time of H. cunea occurred between 2:00 am and 4:00 am, and between 18:00 pm and 20:00 pm. These results provide a useful trapping system for synthetic sex pheromones and fluorescent tubes for better monitoring and control of H. cunea. |
