Sympatric hemipterans such as Riptortus pedestris Thunberg (Hemiptera: Alydidae), Plautia stali 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. pedestri s 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. stali AP alone (lure P), R. 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. stali , were attracted to the traps included P. stali 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. stali together, mixed, or set in parallel, is effective to attract sympatric hemipteran pests of sweet persimmon, R. pedestris , P. stali , G. subpunctatus , and H. halys , in addition to G. rotundatum . Attracting multispecies simultaneously could be a viable option in managing these sympatric pest species. |
