摘要: 探索梨小食心虫性信息素主要成分的合成方法,为梨小食心虫的田间迷向防治提供化合物.梨小食心虫性信息素主要成分是顺-8-十二碳烯乙酸酯(Z8-12: Ac)、反-8-十二碳烯乙酸酯(E8-12: Ac)、顺-8-十二碳烯-1-醇(Z8-12:OH).以1,8-辛二醇和正丁醛等为起始原料,以二甲基亚砜为溶剂,通过Wittig反应合成目标化合物Z/E8-12:OH,顺反比例为94﹕6,产率达42.5%,通过红外、GC、NMR、MS进行鉴定.以合成的性信息素主要成分制备散发器(迷向芯),在桃园进行田间迷向试验.结果表明,自主合成的产物对梨小食心虫有良好的迷向作用.

Abstract: Synthetic method of the oriental fruit moth's sex pheromone was studied to provide mating disruption reagent for field application. The mating disruption reagent includes Z-8-dodecenyl acetate, E-8-dodecenyl acetate and Z-8-dodecenol. Using the cheap industrial materials 1,8-octanediol and butyraldehyde as starting materials and dimethyl sulfoxide as reacting solvent, and through controls the reaction conditions of synthetic reaction, the synthesis yield reached 42.5%. The ratio of Z/E was 94﹕6. The synthesized sex pheromone was tested in a field mating disruption for control of oriental fruit mothby using two types of synthetic sex pheromone products (crude products and purified products) in peach orchards in Taigu County, Shanxi in April 2014. The tests showed good control efficiency against Grapholitha molesta (Busck).
