The attractiveness to male navel orangeworm moth, Amyelois transitella, of various combinations of a four-component pheromone blend was measured in wind-tunnel bioassays. Upwind flight along the pheromone plume and landing on the odor source required the simultaneous presence of two components, (11Z,13Z)-hexadecadienal and (3Z,6Z,9Z,12Z,15Z)-tricosapentaene, and the addition of either (11Z,13Z)-hexadecadien-1-ol or (11Z,13E)-hexadecadien-1-ol. A mixture of all four components produced the highest levels of rapid source location and source contact. In wind-tunnel assays, males did not seem to distinguish among a wide range of ratios of any of the three components added to (11Z,13Z)-hexadecadienal. Dosages of 10 and 100 ng of the 4-component blend produced higher levels of source location than dosages of 1 and 1,000 ng.
在风洞中进行的生物测定中,测量了雄性 navel orangeworm 蛾 Amyelois transitella 对四种成分信息素混合物的各种组合的吸引力。沿着信息素羽流逆风飞行并降落在气味源上需要同时存在两种成分,(11Z,13Z)-十六碳二烯醛和(3Z,6Z,9Z,12Z,15Z)-二十碳五烯,并且添加(11Z,13Z)-十六碳-1-醇或(11Z,13E)-十六碳-1-醇。四种成分的混合物产生了最高水平的快速源定位和源接触。在风洞中进行的试验中,雄性似乎没有区分添加到(11Z,13Z)-十六碳二烯醛中的任何三种成分的广泛比例。与 1 和 1000 ng 的剂量相比,10 和 100 ng 的 4 种成分混合物的剂量产生了更高水平的源定位。
