Capture strategies for the brown marmorated stink bug, (Hemiptera: Pentatomidae), are challenging. Here we developed and evaluated a multimodal trap which combines visual and olfactory stimuli. Visual stimuli consisted of LEDs emitting UV-A and visible light. Olfactory stimuli were comprised of the synthetic aggregation pheromone and odours from trapped individuals. Stink bug attraction at different wavelengths was evaluated in laboratory two-choice bioassays, and different prototypes of the trap were tested in 2021 in natural, agricultural, and urban settings. Traps with a combination of UV-A and blue or green visible wavelengths provided higher attraction (up to ~8-fold) compared to traditional sticky or small pyramidal traps. The concurrent presence of synthetic pheromone and LED had a synergistic effect on positive phototaxis. Further development and implementation of the multimodal trap is discussed for prospective use in attract-and-kill or push-pull strategies.
捕获褐边绿刺蝽（半翅目：蝽科）的策略具有挑战性。在此，我们开发并评估了一种结合视觉和嗅觉刺激的多模式诱捕器。视觉刺激由发出UV-A和可见光的发光二极管组成。嗅觉刺激由合成聚集信息素和被捕个体的气味组成。在实验室双选生物测定中评估了不同波长下臭虫的吸引力，并于2021年在自然、农业和城市环境中测试了诱捕器的不同原型。与传统粘性或小型金字塔形诱捕器相比，结合UV-A和蓝色或绿色可见波长的诱捕器具有更高的吸引力（高达约8倍）。合成信息素和发光二极管的同时存在对正向趋光性具有协同作用。讨论了多模式诱捕器的进一步开发和应用，以期用于诱捕杀灭或推拉策略。
