| 比较不同草地贪夜蛾引诱剂的田间诱集效果差异，筛选出长持效期引诱剂使用的缓释载体材料，为草地贪夜蛾的长期种群监测提供重要的理论依据。本研究首先将新型材料海藻酸钙/聚己内酯微球作为缓释载体应用于草地贪夜蛾引诱剂1，对其结构性能进行相关分析；通过田间诱集试验比较引诱剂1、引诱剂2、引诱剂3、引诱剂4、引诱剂5等五种不同草地贪夜蛾引诱剂的田间持续监测诱集效果；利用气相色谱仪定量比较两种诱集效果不同载体材料的引诱剂1（最优）、引诱剂2（最差）中所含性信息素组分的缓释能力。结果表明：新型材料海藻酸钙/聚己内酯微球的蛙卵状球形结可使草地贪夜蛾引诱剂1中信息素组分缓慢释放，室内静置2个月后该载体基本结构保持稳定；五种不同草地贪夜蛾引诱剂的持续诱捕能力对比为：引诱剂1＞引诱剂5＞引诱剂4＞引诱剂3＞引诱剂2，引诱剂1使用80 d仍然具有很强的引诱效果；通过对比诱集持续效果最优及最差的2种引诱剂1、引诱剂2所用载体的缓释性能，发现田间诱集持续效果最好的引诱剂1对草地贪夜蛾性信息素组分的缓释效果显著优于引诱剂2。海藻酸钙/聚己内酯微球作为载体材料可使草地贪夜蛾引诱剂的诱集持效期达80 d以上，可实现对草地贪夜蛾危害周期全覆盖，为持续开展草地贪夜蛾种群监测奠定了重要理论基础。 |

| To provide an important theoretical basis for the long-term population monitoring of Spodoptera frugiperda, we compare the field attraction effects of different lures on S.frugiperda, and select the dispenser material for the best attractant with prolonged release duration. In this study, SA@Ca2+/PCL microsphere was used as lure dispenser material for S. frugiperda. The attraction effects of five different lure compounds in filed monitoring assays were compared. Besides, the release dynamics of pheromone components in lure 1 and lure 2, which were carried with two different dispenser materials were compared by gas chromatography. The results supported that SA@Ca2+/PCL microsphere enabled to release the pheromone component slowly, and the basic structure of the dispenser material remained stable after 2 months in the laboratory. The continuous trapping ability of five different lures were ranked as follows: lure 1>lure 5>lure 4>lure 3>lure 2. It was worthy to note that lure 1 kept strong attraction effect after 80 d in the field. By comparing the sustained-release properties of lure 1 and lure 2 with different attractant effects, it was found that the sustained-release effect of lure 1 with long duration on the pheromone components in field attractant was significantly better than that of lure 2. SA@Ca2+/PCL microsphere has strong dispenser capacity over 80 d, which cover the full damage cycle of S. frugiperda, and this lays an important foundation for the continuous monitoring population of S. frugiperda. |
