Abstract

•A multiple pheromone trap (MP trap) attracted three sympatric hemipteran species.•MP trap attracted a tachinid parasitoid of hemipterans, Gymnosoma rotundatum, too.•Attractiveness of the traps was not decreased, compared with each separated trap.•Using MP trap might be economical for monitoring the hemipterans and parasitoid.

Sympatric hemipterans such as Riptortus pedestris Thunberg (Hemiptera: Alydidae), Plautia stali Scott (Hemiptera: Pentatomidae), and Halyomorpha halys Stål (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. 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.
