Ethyl (2E, 4Z)-2,4-decadienoate, a pear-derived volatile, is a species-specific, durable, and highly potent attractant to the codling moth (CM), Cydia pomonella (L.), a serious pest of walnuts, apples, and pears worldwide. This kairomone attracts both CM males and virgin and mated females. It is highly attractive to CM in both walnut and apple orchard contexts, but has shown limited effectiveness in a pear orchard context. Rubber septa lures loaded with ethyl (2E, 4Z)-2,4-decadienoate remained attractive for several months under field conditions. At the same low microgram load rates on septa, the combined gender capture of CM in kairomone-baited traps was similar to the capture rate of males in traps baited with codlemone, the major sex pheromone component. The particular attribute of attracting CM females renders this kairomone a novel tool for monitoring population flight and mating-ovipositional status, and potentially a major new weapon for directly controlling CM populations.
(2E, 4Z)-2,4-癸二烯酸乙酯是一种源自梨的挥发性物质,是一种对苹果蠹蛾具有物种特异性、持久性且高效的引诱剂。苹果蠹蛾是一种严重危害全球核桃、苹果和梨的害虫。这种利它素能吸引苹果蠹蛾的雄性以及未交配和已交配的雌性。在核桃园和苹果园环境中,它对苹果蠹蛾具有高度吸引力,但在梨园环境中效果有限。装有(2E, 4Z)-2,4-癸二烯酸乙酯的橡胶塞诱捕器在田间条件下几个月内仍具有吸引力。在塞子上相同的低微克加载率下,用利它素诱饵诱捕器捕获的苹果蠹蛾雌雄总数与用主要性信息素成分性诱剂诱捕器捕获的雄性捕获率相似。吸引苹果蠹蛾雌性这一特殊属性使这种利它素成为监测种群飞行和交配产卵状态的新工具,并有可能成为直接控制苹果蠹蛾种群的主要新武器。
