[Aim]  To investigate the effectiveness of using pheromones to disrupt the mating of the striped rice stem borer, Chilo suppressalis, the rice leaf-roller, Cnaphalocrocis medinalis, the pink stem borer, Sesamia inferens, as well as a non-targeted pest, the brown planthopper, Nilaparavata lugens. [Methods]  High-dose, multi-target sex pheromone dispensers and pheromone traps were deployed in paddy fields and the number of adult moths of the above species captured, the amount of crop damage, the larval density of pests, and the abundance of brown planthoppers, were monitored. [Results] Pheromone dispensers effectively disrupted the mating behavior of Ch. suppressalis, Cn. medinalis and S. inferens, and significantly reduced the number of adults of these species captured. The average, total, disruption rates for Ch. suppressalis, Cn. medinalis and S. inferens moths were, 86.84% ±1.69%, 86.18% ±2.16%, and 86.13% ±1.92%, respectively. The average abundance of Ch. suppressalis adults and larvae in the treatment area were 81.08% ± 4.73% and 85.25% ± 4.89%, respectively, less than in the control area. The average abundance of adult Cn. medinalis was 90.63% ± 3.06% less than in the control area, whereas the average abundance of S. inferens adults and larvae in the treatment area were 56.85% ± 3.53% and 54.97% ± 3.52%, respectively, less abundant than in the control area. The abundance of N. lugens in the treatment area was significantly lower than in the control, with an average reduction of 83.54% ± 2.29%(t=4.12, df=18, P<0.001).[Conclusion]  Multi-targeted sex pheromone dispensers effectively controlled rice yellow stem borers, rice pink stem borers and rice leaf rollers, by disrupting their mating behavior, and may also indirectly suppress the population of rice planthoppers by protecting populations of their natural enemies in the field.
