was used for structure identification. Afterward, their electrophysiological and behavioral activity was evaluated in the laboratory and field. Herein, we eventually determined two active components, E-11-tetradecenyl acetate (E11-14:Ac) and Z-11-tetradecenyl acetate (Z11-14:Ac), at a ratio of 96:4, as the sex pheromone of P. machaeralis. The identification of sex pheromones would facilitate the development
叶害虫Pyrausta machaeralis (鳞翅目:Crambidae)是我国柚木( Tectona grandis )的严重害虫。昆虫信息素的应用作为一种环境友好型害虫综合治理(IPM)技术被广泛应用。在本研究中,收集了P. machaeralis雌性性信息素腺的粗提物,然后使用气相色谱/触角电检测 (GC/EAD) 和气相色谱-质谱 (GC-MS) 进行分析。红外光谱(IR)和核磁共振(NMR)光谱的结合用于结构鉴定。随后,他们的电生理和行为活动在实验室和现场进行了评估。在此,我们最终确定了两种活性成分, E -11-乙酸十四碳烯酯( E 11-14:Ac)和Z -11-乙酸十四碳烯酯( Z 11-14:Ac),其比例为96:4,作为性别P. machaeralis的信息素。性信息素的鉴定将有助于制定监测和控制P. machaeralis野外种群的有效策略。
