Noctuid pests, including tobacco budworm (Chloridea virescens (Fab.)) and bollworm (Helicoverpa zea (Boddie)), are significant pests of southern row crops including cotton (Gossypium hirsutum L.), corn (Zea mays L.), and soybean (Glycine max (L.) Moench.). This pest complex is seasonally monitored through Hartstack traps that are baited with synthetic lepidopteran pheromones across the southern United States. We examined bycatch from the noctuid traps deployed across the Mississippi Delta in 2015, 2016, and 2017 for the presence of bees. The most abundant species collected were honey bees (Apis mellifera L.), bumble bees (Bombus spp.), and long-horned bees (Melissodes spp.); these three genera accounted for 82.4% of specimens collected. We also evaluated the proportion of local- and landscape-level habitats on the abundance and richness of the bees caught as bycatch. The proportion of natural and semi-natural habitat affected the abundance and richness of bees collected at the landscape level, but not at more local scales. Additional research is needed to better understand these interactions between bycatch and landscape factors to minimize non-target collections.

景观对在信息素陷阱中捕获的夜蛾作物害虫（鳞翅目：夜蛾科）的本地蜜蜂（膜翅目：Anthophila）的影响

夜蛾害虫，包括烟草芽虫 (Chloridea virescens (Fab.)) 和棉铃虫 (Helicoverpa zea (Boddie))，是包括棉花 (Gossypium hirsutum L.)、玉米 (Zea mays L.) 和大豆在内的南方行作物的重要害虫（最大甘氨酸（L.）Moench。）。这种害虫复合体通过美国南部的合成鳞翅目信息素诱饵的 Hartstack 陷阱进行季节性监测。我们检查了 2015 年、2016 年和 2017 年在密西西比三角洲部署的夜光捕集器的兼捕物中是否存在蜜蜂。收集到的最丰富的物种是蜜蜂 (Apis mellifera L.)、大黄蜂 (Bombus spp.) 和长角蜜蜂 (Melissodes spp.)；这三个属占采集标本的82.4%。我们还评估了当地和景观水平栖息地的比例，以作为兼捕的蜜蜂的丰度和丰富度。自然和半自然栖息地的比例影响了在景观层面收集的蜜蜂的丰度和丰富度，但在更局部的尺度上没有影响。需要进一步研究以更好地了解兼捕和景观因素之间的这些相互作用，以尽量减少非目标收集。
