【目的】 验证我国草地贪夜蛾Spodoptera frugiperda主要性诱产品的诱集效果、专一性、持效性和稳定性，丰富我国草地贪夜蛾监测防控技术手段。【方法】 2020年10月23日至12月29日，在我国草地贪夜蛾发生严重的云南寻甸，田间试验了中捷四方生物科技股份有限公司（ZJ）、宁波纽康生物技术有限公司（NK）、深圳百乐宝生物农业科技有限公司（BLB）和中国农业科学院植物保护研究所（ZB）4种性诱产品直接试验（ZJ-0、NK-0、BLB-0、ZB-0）和田间放置30 d（ZJ-30、NK-30、BLB-30、ZB-30）计8个处理对目标害虫和杂虫的诱集量，统计累计68 d的总诱蛾量、日均诱蛾量、最高和次高蛾峰值，以及捕获率及其变异系数、杂虫率。【结果】 综合总诱蛾量、日均诱蛾量、最高和次高蛾峰值，8个处理诱集效果由高至低依次为ZJ-30、NK-0、BLB-0、ZB-0、NK-30、ZJ-0、BLB-30和ZB-30；捕获率以ZJ-30最高，其次是BLB-0和NK-0，两者无差异，再次是ZB-0；4种产品的稳定性由高至低依次为NK、BLB、ZJ和ZB。BLB-0、NK-0和ZB-0诱到黄地老虎Agrotis segetum、劳氏粘虫Mythimna loreyi和异色瓢虫Harmonia axyridis 3种杂虫，杂虫率最高为2.08%。【结论】 持效性方面，ZJ和BLB两种产品可保证80 d的诱集效果，NK和ZB有50 d的诱集效果；稳定性方面，以NK、BLB产品表现较优；专一性方面，ZJ未诱到杂虫，另外3种杂虫率较低。建议草地贪夜蛾监测上优先选用稳定性较好的NK和BLB，且30 d更换诱芯；防治上4种产品均可用，优先选用诱蛾量高、持效期长的ZJ、NK和BLB，50-80 d更换一次诱芯。
英文摘要：
[Objectives] To evaluate the attractiveness, specificity, persistence and stability of the main sex pheromone lures used to trap Spodoptera frugiperda in China, and thereby improve the monitoring and control of this pest. [Methods] The number of S. frugiperda and other insects trapped using different experimental lure products was recorded and compared during a major S. frugiperda outbreak in Xundian, Yunnan province between October 23 and December 29, 2020. Data collected included the total trap catch, daily average catch, the highest, and second highest, capture peaks of S. frugiperda, as well as the capture rate, its coefficient of variation and by-catch rate over 68 days. [Results] The effectiveness of the 8 pheromone lures could be ranked from high to low in terms of total S. frugiperda trap catch, daily average S. frugiperda catch, and the highest, and second highest, S. frugiperda capture peaks, as follows: ZJ-30 > NK-0 > BLB-0 > ZB-0 > NK-30 > ZJ-0 > BLB-30 > ZB-30. Traps with the ZJ-30 lure had the highest capture rate, followed by those with the BLB-0 and NK-0 lures. Lures can be ranked in terms of stability, from high to low, as follows: NK > BLB > ZJ > ZB. The highest proportion of non-target pests (2.08%) were caught in traps with the BLB-0, NK-0 and ZB-0 lures, which trapped Agrotis segetum, Mythimna loreyi and ladybird beetles. [Conclusion] The ZJ and BLB lures continued to trap insects for 80 days, whereas NK and ZB were only effective for 50 days. The NK and BLB products were the most stable, whereas, ZJ was the most species-specific lure. We recommend that the NK and BLB lures should be preferentially selected for monitoring S. frugiperda on the basis of their superior stability, and that lure cores should be replaced within 30 days. All four sex pheromone products can effectively control S. frugiperda, however, the ZJ, NK and BLB lures are the best because of their higher capture rates and longer effective period. Lure cores should be replaced once every 50-80 days.
