In this study the adulticidal and larvicidal effect of tansy, Tanacetum vulgare L. (Asteraceae) essential oil (EO) was estimated against four noxious stored-product insect species; Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), Tribolium confusum Jacquelin du Val (Coleoptera: Tenebrionidae), Tenebrio molitor L. (Coleoptera: Tenebrionidae) and Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae). The EO chemical composition, as determined by GC-MS, was dominated by oxygenated monoterpenes (68.2%), with borneol (13.6%), umbellulone (11.7%), artemisia ketone (9.3%), cis-chrysanthenol (6.9%), camphor (5.9%), and terpinen-4-ol (5.5%) as the major constituents. This profile was quite different from those previously reported from other T. vulgare European accessions which are characterized by high content of the toxic trans-thujone. The T. vulgare EO was applied as wheat protectant at two concentrations of 500 and 1000 ppm. Adult and larval mortality levels were estimated after 4, 8 and 16 h and 1, 2, 3, 4, 5, 6 and 7 days. Tanacetum vulgare EO caused complete mortality (100%) to T. castaneum larvae, but only 25.6% to adults at 1000 ppm 6 and 7 days post-exposure, respectively. The mortality rates of T. confusum larvae and adults were 56.7 and 8.9% on wheat treated with 1000 ppm EO, respectively after 7 days of exposure. The ΕΟ caused moderate mortality to T. molitor adults (52.2%), and low mortality to larvae (8.9%), at 1000 ppm at the end of the experimental period. High mortality of O. surinamensis larvae (93.3%) was noticed at 1000 ppm after 7 days of exposure, while only 13.3% of the exposed adults were dead at the same concentration and exposure interval. Overall, the T. vulgare EO could be considered as a potential wheat protectant for the management of important stored-product insects. However, its efficacy depends on the species and the life stage of the target pest.

在这项研究中，评估了艾菊 ( Tanacetum vulgare L. (Asteraceae)) 精油 (EO) 对四种有害贮藏昆虫物种的杀成虫和杀幼虫作用；Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), Tribolium confusum Jacquelin du Val (Coleoptera: Tenebrionidae), Tenebrio molitor L. (Coleoptera: Tenebrionidae) 和Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae)。由 GC-MS 测定的 EO 化学成分以含氧单萜 (68.2%)、冰片 (13.6%)、伞形酮 (11.7%)、蒿酮 (9.3%)、顺式-菊醇 (6.9%)、樟脑 (5.9%) 和萜品烯-4-醇 (5.5%) 作为主要成分。这种概况与之前报道的其他欧洲品种T. vulgare品种完全不同，后者的特点是毒性反式-thujone含量高。的大麦T. EO在500和1000ppm的两个浓度施加小麦保护剂。在 4、8 和 16 小时和 1、2、3、4、5、6 和 7 天后估计成虫和幼虫的死亡率水平。Tanacetum vulgare EO 导致T. castaneum幼虫完全死亡 (100%) ，但在暴露后 6 天和 7 天，1000 ppm 的成虫仅导致25.6%。T. confusum的死亡率暴露 7 天后，用 1000 ppm EO 处理的小麦的幼虫和成虫分别为 56.7% 和 8.9%。所述ΕΟ引起中度死亡率黄粉虫成年人（52.2％）和低死亡率的幼虫（8.9％），在1000ppm的在实验期结束时。暴露 7 天后，1000 ppm的O. surinamensis幼虫死亡率很高（93.3%），而在相同浓度和暴露间隔下，只有 13.3% 的暴露成虫死亡。总体而言，T. vulgare EO 可被视为一种潜在的小麦保护剂，用于管理重要的储藏产品昆虫。然而，其功效取决于目标害虫的种类和生命阶段。
