Lures that are used to attract German cockroaches, Blattella germanica (L.), to traps were compared in olfactometer assays in the laboratory and in trapping experiments in cockroach-infested homes and a swine farm. In olfactometer assays, AgriSense GP-2 was the most attractive lure, followed by peanut butter, and distiller's grain. Other lures, including Trapper tablet; Victor pheromone, a crude fecal extract that ostensibly contains B. germanica aggregation pheromone; and Victor food lure elicited upwind orientation from <50% of the test insects. Peanut butter and distiller's grain were equally attractive in trapping experiments in swine production barns and they captured significantly more cockroaches than the GP-2 tablet or the Victor pheromone lure; the commercial lures failed to attract significantly more cockroaches than the unbaited control traps. When tested against blank controls, cockroaches preferred to rest in shelters that contained the aggregation pheromone-based lure (Victor), but this lure was the least attractive to cockroaches in olfactometer assays. These results do not support claims that commercial crude fecal extracts attract cockroaches to traps, and they highlight a need for developing more attractive lures for detection of cockroaches and for monitoring populations.
在实验室的嗅觉测定试验以及蟑螂滋生的家庭和养猪场的诱捕实验中，对用于将德国小蠊（Blattella germanica (L.)）吸引到诱捕器的诱饵进行了比较。在嗅觉测定试验中，AgriSense GP - 2是最具吸引力的诱饵，其次是花生酱和酒糟。其他诱饵，包括诱捕片剂；Victor信息素（一种表面上含有德国小蠊聚集信息素的粗粪便提取物）；以及Victor食物诱饵，能使不到50%的受试昆虫向上风方向移动。在养猪场的诱捕实验中，花生酱和酒糟的吸引力相当，它们捕获的蟑螂比GP - 2片剂或Victor信息素诱饵显著更多；这些商业诱饵吸引的蟑螂数量并未比未放置诱饵的对照诱捕器显著更多。当与空白对照进行测试时，蟑螂更喜欢在含有基于聚集信息素的诱饵（Victor）的遮蔽物中休息，但这种诱饵在嗅觉测定试验中对蟑螂的吸引力最小。这些结果不支持商业粗粪便提取物能将蟑螂吸引到诱捕器的说法，并且突出了开发更具吸引力的诱饵用于蟑螂检测和种群监测的必要性。
