Controlling Chilo suppressalis and Scripophaga incertulas by using synthetic sex pheromone is an environment-friendly alternative to chemical insecticide. New sex pheromone lures (named SM lures 1, 2, 3, 4 and 5) for both C. suppressalis and S. incertulas males were prepared and tested in rice field in the flight periods of overwintering and 1st generation during 1998–2001 when standard C. suppressalis lure (CL) and S. incertulas lure (SL) were used as the control lures. The SM lures contained 4-component (Z9-hexadecenal, Z11-hexadecenal, Z13-octadecenal and hexadecenal) blends with different ratio and dosage. CL lure contained Z9-hexadecenal, Z11-hexadecenal and Z13-octadecenal and SL lure contained Z9-hexadecenal, Z11-hexadecenal and hexadecenal and 5 types of SM lures were attractive to both male C. suppressalis and S. incertulas. Average catches per week per trap of 5 types of SM lures were 229.4, 158.0, 253.0, 76.4 and 160.6 for over-wintering, and 129.5, 96.8, 157.1, 50.2 and 86.2 for the 1st generations respectively. Among the 5 types of SM lures, SM1 and SM3 were more attractive than other three types of SM lures.
