Abstract

Long's Braya, Braya longii Fernald (Brassicales: Brassicaceae), is an endangered plant in the family Brassicaceae found only on the Limestone Barrens of the Great Northern Peninsula of Newfoundland, Canada. Conservation of this species hinges on management of pests, diseases, and disturbances, which threaten their small populations. In particular, a global agricultural pest, diamondback moth, Plutella xylostella L. (Lepidoptera: Plutellidae), causes significant damage to persistence of B. longii and contributes to possible extinction. This study investigates if there are key volatiles that attract P. xylostella to B. longii, thereby contributing to the pest's impact on the plant. Headspace collections, GC-MS, and GC-EAD revealed a unique volatile profile for B. longii, with (E)-2-nonenal as a key volatile that elicited strong antennal responses in P. xylostella. Oviposition assays confirmed female preference for E2-nonenal-baited radishes. This finding has implications for P. xylostella pest management, highlights the importance of chemical ecology in both crop protection and endangered species conservation.

濒危物种龙舌兰挥发物对小菜蛾产卵选择的影响。
龙舌兰属植物(Braya longii Fernald,芸苔科)是一种濒临灭绝的芸苔科植物,仅生长在加拿大纽芬兰大北半岛的石灰岩贫瘠地带。对这一物种的保护取决于对害虫、疾病和干扰的管理,它们威胁着它们的小种群。特别是一种全球性的农业害虫小菜蛾(Plutella xylostella L.),对长尾蛾的持久性造成了严重的破坏,并可能导致其灭绝。这项研究调查了是否有关键挥发物吸引小菜蛾到长叶白蝇,从而促进害虫对植物的影响。顶空收集、气相色谱-质谱和气相色谱- ead揭示了长叶假单胞菌独特的挥发性特征,其中(E)-2-壬烯醛是引起小菜假单胞菌强烈天线响应的关键挥发性物质。产卵试验证实雌性偏好e2 -壬烯醛诱饵萝卜。这一发现对小菜蛾有害生物管理具有重要意义,强调了化学生态学在作物保护和濒危物种保护中的重要性。
