摘  要:利用真空抽气压缩装置获得柑桔大实蝇[Dacuscitri(chen)]雌成虫释放的性信息物质,经过二氯乙烷溶剂洗脱得到性信息素提取液。室内生物测定结果表明:该提取液对大实蝇雄成虫具有明显的性兴奋刺激反应,如摆动触角、频频振翅、腹部翘起、伸出抱握器等,两种室内测定方法的反应率分别达95%和933%。该结果为进一步探明柑桔大实蝇性信息素成分、结构及人工合成性诱剂提供了依据。The relative components of sex pheromone released by adult female Chinese citrus fly (Dacus citri) were obtained by vacuum compressor on. The sex pheromone extracts was collected by washing with dichloroethane solution. The two experiments demonstrated that the extracts caused obvious sex stimulating reaction of Chinese citrus fly, such as, antenna pendulum, wing vibration, abdomen lift and harpago stretch, etc. The ratio of positioe reaction in the two experiments was 95% and 93.3% respectively. The experiments provided important theoretical basis for further study on the components of the sex pheromone of Chinese citrus fly and their structure as well as the synthesis of man-made products.
