A series of laboratory and field experiments were performed to assess the responses of (Herbst) and other stored-product beetles to pheromone-baited traps and trap components. A commercial pitfall trap called the Flit-Trak M, the predecessor to the Dome trap, was superior in both laboratory and field experiments over the other floor trap designs assessed at capturing walking . In field experiments, (L.) and (Stephens) both preferred a sticky trap to the pitfall trap. Although the covered trap is effective at capturing several other species of stored product beetles, the synthetic aggregation pheromone lure is critical for the pitfall trap's efficacy for . Although the food-based trapping oil used in the pitfall trap was not found to be attractive to when assayed alone, it had value as an enhancer of the pheromone bait when the two were used together in the trap. A dust cover modification made to go over the pitfall trap was effective in protecting the trap from dust, although the trap was still vulnerable to dust contamination from sanitation techniques that used compressed air to blow down the mill floors. Capture of in the modified trap performed as well as the standard trap design in a non-dusty area of a flour mill, and was significantly superior over the standard trap in a dusty area. responded in flight outside a flourmill preferentially to multiple funnel traps with pheromone lures compared to traps without pheromone.
进行了一系列实验室和田间试验，以评估赫氏皮蠹（Herbst）和其他仓储甲虫对信息素诱饵诱捕器及诱捕器组件的反应。一种名为Flit-Trak M的商用陷阱式诱捕器（即Dome诱捕器的前身），在实验室和田间试验中，在捕获行走的赫氏皮蠹方面，比评估的其他地面诱捕器设计都更具优势。在田间试验中，赤拟谷盗（L.）和谷蠹（Stephens）都更喜欢粘性诱捕器而非陷阱式诱捕器。尽管有盖诱捕器在捕获其他几种仓储甲虫方面很有效，但合成的聚集信息素诱饵对于陷阱式诱捕器捕获赫氏皮蠹的功效至关重要。尽管单独检测时发现陷阱式诱捕器中使用的基于食物的诱捕油对赫氏皮蠹没有吸引力，但当两者在诱捕器中一起使用时，它作为信息素诱饵的增强剂具有价值。对陷阱式诱捕器进行的防尘罩改装有效地保护了诱捕器免受灰尘影响，尽管该诱捕器仍易受到使用压缩空气吹扫工厂地面的清洁技术造成的灰尘污染。在面粉厂的无尘区域，改装后的诱捕器捕获赫氏皮蠹的效果与标准诱捕器设计相当，而在多尘区域则明显优于标准诱捕器。与没有信息素的诱捕器相比，面粉厂外飞行的赫氏皮蠹对带有信息素诱饵的多个漏斗形诱捕器反应更强烈。
