Abstract To assess the susceptibility of pseudocereals (amaranth and quinoa), minor cereals (teff and millet), and oilseeds (chia and hemp), now commercially available on the European market, to attacks by polyphagous and cosmopolitan insect pests, laboratory tests were set up. Tests involving controlled infestation of seeds, using laboratory-bred insects (Tenebrio molitor, Tribolium confusum, Oryzaephilus surinamensis, Cryptolestes pusillus and Plodia interpunctella), were carried out in a climatic chamber at 23 ± 2 °C and 65 ± 5% R.H.. Development time, the number of adults and the weight of these adults were evaluated. The results show that each considered foodstuff has a different susceptibility to infestation and differences both in the number of adults emerged and in their weight compared to control. Millet was the only product that allowed larval development up to the adult stage for all the species examined. No species developed on amaranth. T. confusum and O. surinamensis reached the adult stage on the greatest number of products, 5 and 4 respectively; C. pusillus and T. molitor completed their life cycles on only two commodities: millet and teff, while P. interpunctella only on millet and hemp seeds. Considering the impact of the different pests on the studied grains, T. confusum was the only species able to develop on all the grains, but the number of emerged adults was lower than on the standard diet. These results show that, even if these commodities are new in the European market, they are susceptible to the infestation of common stored product pests that could led to a removal from the market of a contaminated stock, so a continuous monitoring is needed.

最近引入意大利市场的谷物和种子的虫害易感性：实验评估

摘要 为了评估伪谷物（苋菜和藜麦）、次要谷物（画眉草和小米）和油籽（奇亚籽和大麻），现在在欧洲市场上可买到，对多食性和世界性害虫攻击的敏感性，进行了实验室测试。向上。在 23 ± 2 °C 和 65 ± 5% RH 的气候室中，使用实验室培育的昆虫（黄粉虫、迷惑蚴、Oryzaephilus surinamensis、Cryptolestes pusillus 和 Plodia interpunctella）对种子进行控制侵染的测试。评估发育时间、成虫数量和这些成虫的体重。结果表明，与对照相比，每种考虑的食品对侵染的易感性和出现的成虫数量和体重都存在差异。小米是唯一允许所有被检查物种的幼虫发育到成虫阶段的产品。没有在苋菜上发育的物种。T. confusum 和 O. surinamensis 达到成虫期的产品数量最多，分别为 5 和 4；C. pusillus 和 T. molitor 仅在两种商品上完成其生命周期：小米和画眉草，而 P. interpunctella 仅在小米和大麻种子上完成。考虑到不同害虫对所研究谷物的影响，T. confusum 是唯一能够在所有谷物上发育的物种，但出现的成虫数量低于标准饮食。这些结果表明，即使这些商品是欧洲市场上的新商品，它们也容易受到常见储存产品害虫的侵袭，这可能导致受污染的库存从市场上撤出，
