Abstract

(E)-β-Farnesene, the major component of the alarm pheromone of many aphids, is prepared in 65% yield by passing commercial nerolidol through an evacuated column of alumina, treated with pyridine, at 200° C. The product is stored without air and applied to aphids as vapor at low speed (ca. 230 mm/sec) in air or nitrogen. The response of eight economically important aphid species was assessed in the laboratory; over 90% ofMyzus persicae responded in a large scale trial.

摘要

(E)-β-法呢烯是许多蚜虫报警信息素的主要成分，通过将商业的香叶醇在 200°C 通过真空氧化铝柱，用吡啶处理，以 65%的产率制备。产品在没有空气的情况下储存，并在空气或氮气中以低速（约 230mm/sec）作为蒸汽应用于蚜虫。在实验室中评估了八种具有经济重要性的蚜虫物种的反应；在大规模试验中，超过 90%的桃蚜有反应。
