| 选取甘肃省12个苹果蠹蛾发生县区,研究了迷向防治技术对苹果蠹蛾的防治效果。结果表明:在种群密度较低(平均蛀果率在1%以下)的果园(连片面积17 hm2),采用迷向防治技术, 即在诱捕到第1头苹果蠹蛾成虫(4月末5月初)后进行第1次悬挂迷向条(120~150根/hm2),7月中旬进行第2次补充悬挂,可有效控制苹果蠹蛾为害,成虫诱蛾量和蛀果率分别较对照下降90.8%和92.6%,成虫无明显的诱集高峰; 采用迷向防治的果园,增加化学防治次数,对防治效果影响不显著(P>0.05)。本研究证实苹果蠹蛾迷向防治技术有较好的防治效果,虽然防治成本相对较高,但减少了环境污染,是未来值得推广的绿色防控技术措施。 |
| 英文摘要: |
| Effect of mating disruption on codling moth, Cydia pomonella, was investigated in Gansu Province. Mating disruption was applied at biofix (first consistent moth activity at the end of April to early May) for full effectiveness. Dispensers were placed in trees at a density of 120-150 /hm2. The results showed that mating disruption could effectively control codling moth infestation in low density population (average infested fruit rate was below 1%) at 17 hectare contiguous orchard. The percent of trapped male moths and damaged fruits decreased 90.8% and 92.6%, respectively. There were no obvious trapping peaks by using mating disruption. There was no significant influence on control effect (P>0.05) when increased application times of chemical control in orchards for matting disruption. Although the cost of mating disruption was relatively high, it is an environmentally safe plant protection strategy, and has good control effect on codling moth, thus it can be recommended to be used for codling moth control. |
