| 为更好地发挥性诱捕器对棉花主要害虫绿盲蝽 Apolygus lucorum 、棉铃虫 Helicoverpa armigera 和甜菜夜蛾 Spodoptera exigua 的监控及诱杀作用, 进一步优化性诱捕器田间设置技术, 笔者研究了不同悬挂高度对3种害虫性诱捕器田间诱集效果的影响。结果表明, 悬挂高度对3种害虫的诱集效果均存在显著影响, 绿盲蝽性诱捕器悬挂高度高于棉株顶尖40 cm时效果最好, 与顶尖持平和高于顶尖20 cm的诱集效果略低, 三者差异不显著; 棉铃虫性诱捕器悬挂高度0~40 cm时诱集效果均较好, 诱捕器处于顶尖以下时诱集效果显著降低; 甜菜夜蛾性诱捕器悬挂高度在高于顶尖20 cm和40 cm时诱集效果差异不显著, 高于顶尖40 cm时诱集效果最好。棉花打顶前, 绿盲蝽和棉铃虫性诱捕器随着棉花株高变化可适当减少调整频次, 但低于棉花顶尖时应及时调整。 |
| 英文摘要: |
| Apolygus lucorum, Helicoverpa armigera and Spodoptera exigua are the main pests on cotton. In order to exploit and make better use of sex pheromone traps for monitoring and managing, we compared the trapping efficacy of sex pheromone traps with different hanging heights. The results showed that the hanging height had an effect on the trapping efficacy. The effect was the best when the hanging height of A.lucorum trap at 40 cm above the top of cotton, and the trapping efficacy was slightly lower when the top was flat and hanging height at 20 cm above the top of cotton, and the difference among the three was not significant. The trapping efficacy was better when the hanging height of H. armigera trap at 0-40 cm, and when the sex pheromone lure was at 20 cm under the top of cotton, the trapping efficacy was significantly reduced. There was no significant difference when the hanging height of S. exigua at 20 cm and 40 cm, and the trapping efficacy was the best when it was at 40 cm above the top of cotton. Before topping, the frequency of adjustment of the sex pheromone traps for A.lucorum and H. armigera could be decreased with the change of cotton plant height, but it should be adjusted in time when it was lower than the top of cotton. |
