Abstract： [Objectives] To confirm the efficacy and benefit of using different integrated multiple green control techniques for the Asian corn borer, Ostrnia furnacalis (Guenée). [Methods] The efficacy of 6 different integrated multiple green control techniques for the Asian corn borer were compared in corn fields. Efficacy was assessed by control efficacy and decrease of corn yield loss, and also by corn yield and quality and input-output ratio. [Results] The control efficacy of the six methods was 83.55%, 85.26%, 87.28%, 89.57%, 84.74% and 86.75%, and the associated reduction of corn yield loss was 15.55%, 16.13%, 16.97%, 17.53%, 15.66% and 16.50%, respectively. The input-output ratio for each technique was 1︰57.23, 1︰25.76, 1︰19.41, 1︰17.53, 1︰9.23 and 1︰8.48. The 6 integrated multiple green control techniques assessed were projection-type, moth-killing lamps + suspended sex pheromone cores, projection-type moth-killing lamps + Trichogramma release, projection-type moth-killing lamps + Bt WP spray, Trichogramma release + Bt WP spray, sex pheromone traps + Trichogramma release and sex pheromone traps + Bt WP spray. [Conclusion] Trichogramma release + Bt WP spray, projection-type moth-killing lamps + Bt WP spray, projection-type moth-killing lamps + Trichogramma release, Bt WP spray + suspended sex pheromone cores, were the best of the methods evaluated.
