【摘要】 昆虫性信息素在害虫的生物防治中具有用量少，防效良好，对天敌无害等特点，有助于减少化学农药的使用。本文以性信息素前体醇为原料，设计并合成了4种结构新颖的斜纹夜蛾性信息素类似物，包括反-11-十四碳烯丙酸酯、反-11-十四碳烯-2-氯乙酸酯，反-9-十四碳烯-3-甲硫基丙酸酯和反-9-十四碳烯-2,2-二氟乙酸酯。其结构经核磁共振（NMR）、红外（IR）和高分辨质谱（HR-MS）确证。触角电生理试验（EAG）初步测试结果显示，4种性信息素类似物对斜纹夜蛾均具有一定的活性。更多还原

【Abstract】 Insect sex pheromones have the characteristics of low dosage, good control effect, and harmless to natural enemies in the biological control of pests. They help to reduce the use of chemical pesticides. In this article, four structurally novel pheromone analogs were designed and synthesized, using sex pheromone precursor alcohols as raw materials, including trans-11-tetradecenepropionate, trans-11-tetradecene-2-chloroacetate, trans-9-tetradecene-3-methylthiopropionate, and trans-9-tetradecene-2,2-difluoroacetate. Their structures were characterized by NMR, IR and HR-MS. The results of the antennae electrophysiological test(EAG) showed that the four pheromone analogs all had certain activities against Spodoptera litura Fabricius.更多还原
