Abstract：With mark-release-recapture methods, the trapping efficiency of traps with sex pheromone of Prodenia litura and the effect of meteorological factor on trapping efficiency were studied in the field. The results showed that the trapping efficiency was from 7.46 % to 72.46 %. The effective trapping radius of were from 20 m to 40 m. The trapping efficiency to Prodenia litura was determined by meteorological factors: like wind direction，wind speed and the relative humidity. The largest number of Prodenia litura attracted by traps was in the windward of dominant wind direction. Higher speed of wind and lower relative humidity could promote the trapping efficiency at night.
