Sex pheromone monitoring lures from five different commercial sources were compared for their attractiveness to male diamondback moth, Plutella xylostella L. (Lepidoptera: Plutellidae) in canola, Brassica napus L., fields in western Canada. Lures that had the highest pheromone release rate, as determined by aeration analyses in the laboratory, were the least attractive in field tests. Lures from all the commercial sources tested released more (Z)-11-hexadecenal than (Z)-11-hexadecenyl acetate and the most attractive lures released a significantly higher aldehyde to acetate ratio than less attractive lures. Traps baited with sex pheromone lures from APTIV Inc. (Portland, OR) and ConTech Enterprises Inc. (Delta, BC, Canada) consistently captured more male diamondback moths than traps baited with lures from the other sources tested. In two different lure longevity field trapping experiments, older lures were more attractive to male diamondback moths than fresh lures. Pheromone release from aged lures was constant at very low release rates. The most attractive commercially available sex pheromone lures tested attracted fewer diamondback moth males than calling virgin female moths suggesting that research on the development of a more attractive synthetic sex pheromone lure is warranted.
来自五个不同商业来源的性信息素监测诱芯在加拿大西部油菜，甘蓝型油菜的田间对小菜蛾雄性的吸引力进行了比较。通过实验室通气分析确定的具有最高信息素释放率的诱芯在田间测试中最不具吸引力。所有测试的商业来源的诱芯释放的（Z）-11-十六碳烯醛均多于（Z）-11-十六碳烯基乙酸酯，而最具吸引力的诱芯释放的醛与乙酸酯的比例明显高于不那么有吸引力的诱芯。用 APTIV Inc.（波特兰，OR）和 ConTech Enterprises Inc.（加拿大不列颠哥伦比亚省三角洲）的性信息素诱芯诱捕的诱捕器捕获的雄性小菜蛾比用其他测试来源的诱芯诱捕的诱捕器捕获的雄性小菜蛾多。在两个不同的诱芯寿命田间诱捕实验中，旧诱芯比新鲜诱芯对雄性小菜蛾更具吸引力。老化诱芯的信息素释放率保持在非常低的恒定水平。测试的最具吸引力的市售性信息素诱芯吸引的雄性小菜蛾比鸣叫的处女雌蛾少，这表明有必要研究开发更具吸引力的合成性信息素诱芯。
