The results showed that the averages trap caught of rice srem borer was from 1.95 males to 4.19 males (the maximum was 24 males) per trap every evening during test periods.The numbers of rice stem borer larvae, the rice blight sheath and white ear were decreased 87.70%,76.19% and 90.92% separately in the test plot.
