Abstract: By ‘mark-release-recapture' of fluorescence-labeled Apolygos lucorum, the trapping efficiency of sex pheromone traps for A. lucorum and its affecting factors were investigated in a Xinzheng jujube orchard in June 2015. Adult males reared in the lab were marked with red fluorescent powder and released in the center of the orchard, where sex pheromone traps were set up at certain direction and distance to the released points. Catches in the traps were collected for seven successive days and those labeled with fluorescence were detected. The effective trapping radius of the sex pheromone traps was from 10 m to 30 m, and the best trapping efficiency occurred at 20 m from the release points. The trapping efficiency was affected by meteorological factors, such as wind direction, wind speed and the relative humidity. The largest trap catches was in the windward of dominant wind direction.Regression analysis showed that a significant linear regression between the average night wind speed (x) and trap catches (y), y=0.540+0.232x, and a significant negative correlation between night average relative humidity (x) and trap catches, y=1.887-0.20x. These results indicate that, within a certain range, high night wind speed and low relative night humidity can increase the trapping efficiency.
