摘　　要：The tea tussock moth(Euproctis pseudoconspersa)is one of the most destructive chewing pests in tea plantations and causes a serious allergic reaction on the skin of tea plantation workers.The sex pheromone components of its Japanese population were first identified as 10,14-dimethylpentadecyl isobutyrate(10Me14Me-15:iBu)and 14-methylpentadecyl isobutyrate(14Me-15:iBu),with a stereogenic center.Only 10Me14Me-15:iBu has been identified in the Chinese E.pseudoconspersa population.However,field tests have shown that 10Me14Me-15:iBu cannot meet the demand of effective pest control in China.To develop a high-efficiency E.pseudoconspersa sex pheromone formula,electroantennogram(EAG)recordings of(S)-and(R)-enantiomers of 10Me14Me-15:iBu and 14Me-15:iBu were obtained in the present study.The results demonstrated that the EAG responses of male antennae to(R)-enantiomers were significantly higher than responses to the(S)-enantiomers,and 14Me-15:iBu also elicited EAG activity.Field tests showed that the catch numbers of male moths by(R)-enantiomers were significantly higher(P<0.05)than those of(S)-enantiomers.Addition of 14Me-15:iBu significantly increased the catch numbers of both the(S)-and(R)-enantiomers.The efficient pheromone formula containing 0.75 mg(R)-10Me14Me-15:iBu and 0.1 mg 14Me-15:iBu showed significantly higher attractiveness than commercial pheromone products.Our study demonstrated that(R)-10Me14Me-15:iBu was the major sex pheromone component of E.pseudoconspersa,and 14Me-15:iBu might be the minor sex pheromone component.Furthermore,a high-efficiency sex pheromone formula for E.pseudoconspersa control was defined in this study.
