| 红火蚁Solenopsis invicta Buren是全球百种最具危害性的外来入侵物种之一，严重威胁农林业生产、人畜健康、公共安全及生物多样性。精准高效监测红火蚁是其防控的关键，而诱饵诱集是常用的监测手段。本研究在前期已研发的专业监测诱饵内添加5%、10%及15%的NaCl，并测试其储存期及对红火蚁诱集效果的影响，旨在进一步提升诱饵使用效能。结果表明，NaCl浓度越高，诱饵颜色与气味指标降级延迟效应越显著，说明NaCl对诱饵的腐败具有延缓作用。室内测试发现红火蚁的诱集效果总体上随着诱饵储存期的延长而降低，5% NaCl处理在第19天至第25天期间的诱集效果显著高于未添加NaCl的对照，10% NaCl处理仅在第19天、第22天显著，而15% NaCl处理仅在第16天显著。室外测试发现，前20 d NaCl处理与对照差异不显著；第30天，5% NaCl处理的诱集效果显著高于其他处理与对照。综上所述，添加5% NaCl的诱饵在储存期和诱集效果上均表现最佳，可为开发精准高效且低成本的红火蚁监测诱饵提供科学依据。 |

| Red imported fire ant (Solenopsis invicta Buren) is recognized as one of the world's 100 most detrimental invasive species, posing substantial threats to agricultural and forestry production, human and animal health, public safety, and biodiversity. Accurate and effective monitoring of S. invicta is critical for its prevention and control, with bait trapping being a widely used monitoring method. In this study, 5%, 10%, and 15% sodium chloride (NaCl) were added to a pre-developed specialized monitoring bait to investigate their effects on the bait's storage period and trapping efficacy against S. invicta, with the aim of further enhancing bait performance. Results showed that higher NaCl concentrations significantly delayed deterioration in bait color and odor indicators, suggesting that NaCl retards bait spoilage.Indoor tests revealed that the trapping efficacy of S. invicta generally decreased with prolonged storage. Specifically, the 5% NaCl treatment showed significantly higher trapping efficacy than the NaCl-free control from day 19 to day 25. The 10% NaCl treatment only showed significant superiority on days 19 and 22, while the 15% NaCl treatment was significantly more effective only on day 16. Outdoor field trials indicated no significant differences between NaCl treatments and the control within the first 20 days. However, on day 30, the 5% NaCl treatment exhibited significantly higher trapping efficacy than other treatments and the control. In conclusion, bait with 5% NaCl addition demonstrated optimal performance in both storage period and trapping efficacy, providing a scientific foundation for the development of precise, efficient, and cost-effective monitoring baits for S. invicta. |
