[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.
