A no-choice test was performed to determine survival and reproductive capacity of stored-product insect pests on pecan, Carya illinoensis (Wangenheim) Koch. Insects used were Indianmeal moth, Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae); sawtoothed grain beetle, Oryzaephilus surinamensis (L.) (Coleoptera: Cucujidae); red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae); lesser grain borer, Rhyzopertha dominica (F.) (Coleoptera: Bostrichidae); and rusty grain beetle, Cryptolestes ferrugineus (Stephens) (Coleoptera: Laemophloeidae). Fifty adults of each beetle species or 10 reproductive pairs of P. interpunctella adults were placed in 0.5-liter containers with either whole-shell pecans, cracked-shell pecans, randomly selected in-shell pecans, pecan nutmeats, cracked wheat, or glass beads and held at 28 degrees C, 60-70% relative humidity, and 16:8 (L:D) photoperiod for 2, 4, 6, and 8 wk. Four replications of each insect-diet-interval combination were performed. Larvae of P. interpunctella, O. surinamensis, T. castaneum, C. ferrugineus, and adult P. interpunctella and O. surinamensis developed on cracked and nutmeat pecan diets. R. dominica did not complete reproduction on pecans. Knowledge that these pests can reproduce on stored pecan will assist pecan growers, accumulators, and storage facilities in preventing insect outbreaks on their product.
进行了无选择测试，以确定美洲山核桃（Carya illinoensis（Wangenheim）Koch）上储存的害虫的生存和繁殖能力。所用昆虫为印度谷螟（Plodia interpunctella（Hübner））（鳞翅目：Pyralidae）；锯谷盗（Oryzaephilus surinamensis（L.））（鞘翅目：Cucujidae）；赤拟谷盗（Tribolium castaneum（Herbst））（鞘翅目：Tenebrionidae）；玉米象（Rhyzopertha dominica（F.））（鞘翅目：Bostrichidae）；和锈赤扁谷盗（Cryptolestes ferrugineus（Stephens））（鞘翅目：Laemophloeidae）。每种甲虫 50 只成虫或印度谷螟成虫 10 对生殖对被放置在 0.5 升容器中，容器内装有完整的山核桃、破裂的山核桃、随机选择的山核桃、山核桃仁、碎小麦或玻璃珠，并在 28 摄氏度、60-70%相对湿度和 16:8（L:D）光照条件下保持 2、4、6 和 8 周。每个昆虫-饮食-间隔组合进行了 4 次重复。印度谷螟、锯谷盗、赤拟谷盗、锈赤扁谷盗的幼虫和印度谷螟成虫和锯谷盗成虫在破裂的山核桃和山核桃仁饲料上发育。玉米象不能在山核桃上完成繁殖。这些害虫可以在储存的山核桃上繁殖的知识将帮助山核桃种植者、收集者和储存设施防止其产品上发生虫害。
