Identification of sex pheromone components of Holcocerus hippophaecolus (Lepidoptera: Cossidae) and their biological activities

We identified the structure and component of sex pheromones of Holcocerus hippophaecolus (Lepidoptera: Cossidae), a destructive pest to Hippophae rhamnoidea growing in Northern China. Electroantennogram responses and field trapping effects by sex pheromones with different components were also studied. Seven components in an extract of sex gland were identified: (Z)-3-tetradecen-1-ol, (Z)-3 -tetradecenyl acetate, (E)-3-tetradecen-1-ol, (E)-3-tetradecenyl acetate, (E)-7-tetradecen-1-ol, (E)-7- tetradecenyl acetate and (Z)-9-tetradecenyl acetate. Results of the field trapping tests showed the biological activities of mixtures of two or five components are stronger than any single one.
