Sympatric hemipterans such as Riptortus pedestris Thunberg (Hemiptera: Alydidae), Plautia stall Scott (Hemiptera: Pentatomidae), and Halyomorpha halys Stal (Hemiptera: Pentatomidae) are reported as economic pests of persimmon fruits in Korea and Japan. Multi-attractiveness of the aggregation pheromones (AP) of R. pedestris and P. stali mounted on a single sticky trap was evaluated for the sympatric hemipteran pests of persimmon fruit. Four trap types were prepared: traps mounted with R. pedestris AP alone (lure R), P. stall AP alone (lure P), pedestris and P. stali AP mixed in a septum (lure R P), and traps with two parallel lures (lure R/P). R pedestris was equally captured in traps carrying lures R + P and R/P. P. stali and Gymnosoma rotundatum (Diptera: Tachinidae), a parasitoid of P. stall, were attracted to the traps included P. stall AP lures: P, R + P, and R/P. All traps carrying lure P attracted H. halys and Glaucias subpunctatus (Hemiptera: Pentatomidae), a pest of Japanese cedar and cypress, with no significant difference from control. This study shows that a single trap baited with pheromones of R pedestris and P. stall together, mixed, or set in parallel, is effective to attract sympatric hemipteran pests of sweet persimmon, R pedestris, P. stall, G. subpunctatus, and H. halys, in addition to G. rotundatum. Attracting multispecies simultaneously could be a viable option in managing these sympatric pest species.
