Attractiveness of conspecific stink bugs to adult stink bug-baited traps in soybean fields

The attractiveness of live adult stink bugs used as baits in traps in soybean fields, Milyang, Korea, to conspecific stink bugs was evaluated. Both sexes of bean bug, Riptortus pedestris Fabricius (Hemiptera: Alididae), and one-banded stink bug, Piezodorus hybneri Gmelin (Hemiptera: Pentatomidae), were attracted to conspecific male adults-baited traps. Likewise, both sexes of brown-marmorated stink bug, Halyomorpha halys Stål (Hemiptera: Pentatomidae), and sole bug, Dolycoris baccarum L. (Hemiptera: Pentatomidae), were attracted to traps baited with conspecific male stink bugs. However, in Nezara antennata Scott (Hemiptera: Pentatomidae), both male and female used as baits in traps were attractive to conspecific adults. Accordingly, these results suggest that the only male adults of H. halys and D. baccarum and both sexes of N. antennata are attractive to conspecific male stink bugs.

► We evaluated attractiveness of conspecific stink bugs to adult stink bug-baited traps.
► Both sexes of Riptortus pedestris and Piezodorus hybneri attracted conspecific male adults.
► Both sexes of Halyomorpha halys and Dolycoris baccarum were attracted to conspecific male adults-baited traps.
► Both sexes of Nezara antennata were newly attracted to both sexes of conspecific adults.
