Catch rates of black army cutworm moths,Actebia fennica (Lepidoptera: Noctuidae), were determined for different types of traps and different dispenser loads of sex attractant. Of the five traps tested, highest catch (35 males/per night) was obtained with Uni-Traps, whereas Pherocon 1CP, Delta and Hara traps rapidly became saturated at 9, 6, and 11 males/per night, respectively. Multi-Pher traps, like the Uni-Traps, have a covered vertical cone with a large collecting bucket but only catch about 1/3 of the number of moths (9 males/per night) as the Uni-Traps, thus reducing potential saturation. Red rubber septa loaded with 500 μg of attractant blend gave a consistent catch for at least 60 days; 1000 and 2000 μg loadings lasted for a minimum of 90 days. Polyvinylchloride and red rubber septa dispensers containing 100 μg of attractant had similar catch rates, which decreased rapidly with age. Based on these trap and lure-loading experiments, Multi-Pher traps baited with 1000 μg of attractant in a red rubber septum were selected for future calibration studies between catch density and population fluctuations on susceptible sites. Two years of monitoring results also are reported.
黑条灰灯蛾雄蛾的诱捕率取决于不同类型的诱捕器和不同剂量的性引诱剂。在测试的五种诱捕器中，Uni-Traps 的诱捕率最高（每晚 35 只雄蛾），而 Pherocon 1CP、Delta 和 Hara 诱捕器在每晚 9、6 和 11 只雄蛾时迅速达到饱和。Multi-Pher 诱捕器与 Uni-Traps 类似，具有带大收集桶的覆盖式垂直圆锥体，但诱捕的蛾类数量仅为 Uni-Traps 的 1/3（每晚 9 只），从而降低了潜在的饱和风险。装有 500μg 引诱剂混合物的红色橡胶隔片至少可以持续 60 天保持稳定的诱捕效果；1000μg 和 2000μg 的载药量至少可以持续 90 天。装有 100μg 引诱剂的聚氯乙烯和红色橡胶隔片的诱捕器具有相似的诱捕率，但随着时间的推移迅速下降。基于这些诱捕器和诱芯加载实验，选择在红色橡胶隔片上加载 1000μg 引诱剂的 Multi-Pher 诱捕器，用于未来在易感地点进行诱捕密度和种群波动之间的校准研究。还报告了两年的监测结果。
