Tribolium castaneum (Herbst) is an important pest of stored grain, and benzoquinones secreted by this pest are harmful to humans. T. castaneum has developed strong resistance to fumigants, and an ecofriendly alternative for managing T. castaneum is urgently needed. 1-Octen-3-ol is a major volatile compound present in many mushrooms and fungi. In the current study, the direct toxicity and sublethal and transgenerational effects of 1-octen-3-ol on T. castaneum were investigated. Our results showed that 1-octen-3-ol had strong insecticidal activity against all developmental stages of T. castaneum and repelled T. castaneum adults. 1-Octen-3-ol showed negative effects on the development and reproduction of parental T. castaneum and the subsequent generation: LC₃₀ and LC₅₀ treatments significantly decreased the pupa and adult weights, pupation and emergence rates and fecundity of the parental generation. In addition, LC₅₀ treatment shortened the larval and pupal periods. In the unexposed progeny (F₁) of 1-octen-3-ol-exposed parents, decreased survival and pupation rates as well as reduced pupa and adult weights were observed under LC₃₀ and LC₅₀ treatments. In addition, a model food-system experiment showed that 1-octen-3-ol at 98 μL/L exhibited an efficacy of 100% after 7 days of fumigation and completely eliminated T. castaneum offspring. Although a higher concentration of 1-octen-3-ol was needed to achieve an efficacy equal to that of the positive control, dichlorvos (DDVP), 1-octen-3-ol promoted the seedling growth of wheat seeds, suggesting that the concentration used was not only acceptable but also beneficial for wheat seeds. Overall, 1-octen-3-ol seems to be a promising candidate for use as a fumigant and repellent against T. castaneum as well as a seed protectant.

bol藜（Herbst）是储存谷物的重要害虫，该害虫分泌的苯醌对人体有害。锥栗（T. castaneum）对熏蒸剂具有很强的抵抗力，迫切需要一种生态友好的替代方法来管理锥栗（T. castaneum）。1-Octen-3-ol是许多蘑菇和真菌中存在的主要挥发性化合物。在目前的研究中，直接毒性和对-1-辛烯-3-醇的亚致死和跨代效果赤拟谷盗进行了调查。我们的结果表明1-辛烯-3-醇对锥栗和排斥锥栗的所有发育阶段均具有较强的杀虫活性。大人。1-Octen-3-ol对亲代锥栗和其后代的发育和繁殖显示出负面影响：LC ₃₀和LC ₅₀处理显着降低了亲代的the和成年体重，化脓和出苗率以及繁殖力。此外，LC ₅₀处理可缩短幼虫和p的时间。在LC ₃₀和LC ₅₀下，在1-辛烯-3-醇暴露的父母的未暴露后代（F ₁）中，观察到存活率和化脓率降低，和成年体重降低治疗。此外，模型食品系统实验表明，熏蒸7天后，98μL/ L的1-辛烯-3-醇显示出100％的功效，并完全消除了锥栗木后代。虽然需要更高浓度的1-octen-3-ol才能达到与阳性对照相同的功效，敌敌畏（DDVP），但1-octen-3-ol可以促进小麦种子的幼苗生长，这表明该浓度所用小麦不仅可接受，而且对小麦种子有益。总体而言，1-辛烯-3-醇似乎是有前途的候选物，可用作熏蒸剂和抗锥栗木的驱虫剂以及种子保护剂。
