The invasive brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae), is an important pest of field crops, fruit orchards, commercial vegetables, ornamental plants, and home vegetable gardens. Pheromone-baited traps designed to attract, trap, and kill H. halys are marketed for use in home gardens to reduce damage to plants. To test this assertion, we conducted the following experiment: One group of 15 gardeners placed stink bug traps at the end of a row of tomatoes, Solanum lycopersicum (L.), in their vegetable garden and another group of 14 placed no traps in their garden and served as controls. Gardeners with traps were no more or less likely to have H. halys on tomato plants than those without traps, but the abundance of H. halys on tomato fruits was marginally greater in gardens with traps. However, tomato fruits grown in gardens with traps sustained significantly more injury than tomato fruits grown in gardens without traps. Furthermore, tomato fruits on plants near the trap housed more H. halys than tomato fruits on plants at the end of a row away from the trap. Traps may be useful in identifying gardens where H. halys is likely to be found and ones in which stink bug injury to tomatoes is likely. We found no evidence that stink bug traps protected tomatoes from H. halys, and it appears that the addition of traps to gardens may increase injury to tomato fruits.
入侵性的茶翅蝽，学名Halyomorpha halys（斯塔尔）（半翅目：蝽科），是大田作物、果园、商业蔬菜、观赏植物和家庭菜园的重要害虫。用于吸引、诱捕和杀死茶翅蝽的性诱捕器已投放市场，供家庭菜园使用，以减少对植物的损害。为了验证这一说法，我们进行了以下实验：一组15名园丁在他们菜园的一排番茄（学名Solanum lycopersicum（L.））末端放置了蝽类诱捕器，另一组14名园丁在他们的菜园中未放置诱捕器，作为对照。放置诱捕器的园丁的番茄植株上出现茶翅蝽的可能性与未放置诱捕器的园丁相同，但放置诱捕器的菜园中番茄果实上的茶翅蝽数量略多。然而，放置诱捕器的菜园中种植的番茄果实遭受的损伤明显比未放置诱捕器的菜园中种植的番茄果实更多。此外，靠近诱捕器的植株上的番茄果实比远离诱捕器的一排末端植株上的番茄果实容纳了更多的茶翅蝽。诱捕器可能有助于识别可能发现茶翅蝽的菜园以及茶翅蝽可能对番茄造成损害的菜园。我们没有发现证据表明蝽类诱捕器能保护番茄免受茶翅蝽侵害，而且在菜园中添加诱捕器似乎可能会增加番茄果实的损伤。
