Abstract: Sex pheromone control technology has always been one of the important ways to control Asian corn borer in China. In order to test the trapping effect of different dry trap and different concentration of trap core on male moth of Asian corn borer, the trapping experiment of male moth of corn borer was carried out with fixed or swing trap chamber, borer caliber and trap type. The trapping effect of barrel trap with 4 kinds of sex trap core was studied in experimental fields of different crops. The results showed that:  ① the trapping effect of the trap with fixed trap was better than that with swaying trap in trapping the male moths of corn borer. ② among the plastic traps with different caliber, the outer orifice diameter of 14 cm trap displayed a better effect on trapping male moths, and for the same caliber trap, rubber trap was better than toothpick trap in trapping male moths. ③ compared with bucket trap, plastic trap and triangular plate trap, bucket trap had the best effect on trapping male moths. ④ in corn and rice fields, there were more male moths trapped with 2.6∶1-XP traps, and in soybean fields there were more male moths trapped with 1∶1 traps. To sum up, the larger the trap entered the moths, the better the effect of trapping the male moths of corn borer was, and the better the effect of trapping male moths when the trap was fixed.  The better the effect of trapping male moths with rubber core when the male moths of corn borer were trapped with the same trap. The best sex-inducing cores of different crop fields are different. These  results provided a theoretical basis for the rational use of the sex trap and the sex-induced core to control the Asian corn field.
