Four acetates,Z-5-decenyl acetate,Z-5-,Z-7-, andZ-9-dodecenyl acetates, in microgram ratios of 1∶200∶2∶1 or 1∶200∶6∶2 were excellent, specific sex pheromone blends for capturing male redbacked cutworm moths in cone traps. Blends in ratios of 1∶200∶2∶1 and 2∶200∶2∶1 at 1000 μg/ rubber septum dispenser remained highly effective for 6 weeks under field conditions. The essential minor components,Z-5-decenyl,Z-7-, andZ-9-dodecenyl acetates, became inhibitory at concentrations of about 10% in the blends, and this may be an important general phenomenon in lepidopteran pheromones. Blends involving a parapheromone,Z-5-undecenyl acetate, withZ-5-,Z-7-, andZ-9-dodecenyl acetate, in microgram ratios of 8∶200∶2∶1 or 20∶200∶6∶2 were also excellent specific attractants for this species. TheZ-8-dodecenyl acetate had no obvious effect on the attraction of the redbacked cutworm males.
四种醋酸酯,Z-5-癸烯基醋酸酯、Z-5-、Z-7-和 Z-9-十二烯基醋酸酯,微克比为 1∶200∶2∶1 或 1∶200∶6∶2,是圆锥诱捕器中捕获雄性红背斜纹夜蛾雄蛾的极佳、特异性性信息素混合物。在 1000μg/橡胶隔垫分配器中,比例为 1∶200∶2∶1 和 2∶200∶2∶1 的混合物在田间条件下仍保持高度有效达 6 周。在混合物中,浓度约为 10%时,重要的次要成分 Z-5-癸烯基、Z-7-和 Z-9-十二烯基醋酸酯成为抑制性的,这可能是鳞翅目信息素中的一个重要普遍现象。涉及副信息素 Z-5-十一烯基醋酸酯的混合物,与 Z-5-、Z-7-和 Z-9-十二烯基醋酸酯的微克比为 8∶200∶2∶1 或 20∶200∶6∶2,也是该物种的极佳特异性引诱剂。Z-8-十二烯基醋酸酯对红背斜纹夜蛾雄蛾的吸引力没有明显影响。
