Cigarette beetle, Lasioderma serricorne (F.), is one of the most common stored-product pests. We monitored their population dynamics and distribution in two coffee bean warehouses in New Jersey, USA, using pheromone traps and sticky traps during September 2018-October 2020, and light traps in 2020. The two warehouses only implemented treatment procedures for controlling Indian meal moth (Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae)) during the study period. The first L. serricorne adult appeared on pheromone traps from late May to early June when temperature reached 21-22 °C, and the last L. serricorne adult appeared on pheromone traps from late October to mid-November when temperature dropped to 10-14 °C. The majority of L. serricorne was caught during July-October. Light traps caught 5.5- and 2.2-times more L. serricorne per trap than pheromone traps in Warehouse 1 and 2, respectively. Warehouse 1 had a significantly higher density of L. serricorne than Warehouse 2. The L. serricorne activity peaks were not always clear and varied between year and the two warehouses. Zero to 3 hot spots, where had the largest numbers of L. serricorne, were identified from July to October in each warehouse based on pheromone traps, and their locations were similar through the months both in 2019 and 2020. The L. serricorne counts from pheromone traps placed inside warehouse were at least 2.3-times more than those placed outside. Also, the L. serricorne active period outside of the warehouses was shorter than that from inside of the warehouses.
烟草甲（Lasioderma serricorne (F.)）是最常见的仓储害虫之一。2018年9月至2020年10月期间，我们在美国新泽西州的两个咖啡豆仓库中，使用性诱捕器和粘虫板监测了烟草甲的种群动态和分布情况，并于2020年使用了灯光诱捕器。在研究期间，这两个仓库仅实施了控制印度谷螟（Plodia interpunctella (Hübner)（鳞翅目：螟蛾科））的处理程序。烟草甲成虫最早于5月下旬至6月初出现在性诱捕器上，此时温度达到21 - 22°C，最后一只成虫于10月下旬至11月中旬出现在性诱捕器上，此时温度降至10 - 14°C。烟草甲的捕获高峰大多出现在7月至10月。在仓库1和仓库2中，灯光诱捕器捕获的烟草甲数量分别是性诱捕器的5.5倍和2.2倍。仓库1中烟草甲的密度显著高于仓库2。烟草甲的活动高峰并不总是清晰明显，且在不同年份和两个仓库之间有所变化。根据性诱捕器的数据，在每个仓库中，7月至10月期间可识别出0至3个烟草甲数量最多的热点区域，其位置在2019年和2020年的各个月份中都较为相似。放置在仓库内部的性诱捕器捕获的烟草甲数量至少是放置在外部的2.3倍。此外，仓库外部烟草甲的活跃期比内部短。
