The invention relates to a method for preparing spring-cankerworm sex pheromones. The method includes the steps that alkynol serves as a raw material; hydroxyl is protected by dihydropyran ether; alkynyl and halogenated hydrocarbon are coupled; an acetylation reaction is carried out to generate a compound cis-4-tetradecenyl acetate and a compound cis-6-tetradecenyl acetate, wherein the total yield of the compound cis-4-tetradecenyl acetate and the total yield of the compound cis-6-tetradecenyl acetate are 58.1% and 55.2% respectively. The method has the advantages that the raw material is easy to obtain, the method is simple, the condition is mild, the total yield is high, cost is low, and the method is suitable for large-scale production. The method provides the necessary condition for replacing fruit-pest chemical-pesticide control with the wide application of the spring-cankerworm sex pheromones, and has the high theoretical significance and the quite good application value.
