沙棘木蠹蛾雌蛾性信息素腺体提取物的生物活性研究

Study on Biological Activity of Female Sex Pheromone Extracted from Gland of Holcocerus hippoophaecolus Hua(Lepidoptera:Cossidae)

提取沙棘木蠹蛾雌蛾性信息素腺体分泌物，对雄蛾进行触角电位（EAG）检测和风洞及田间活性试验。结果表明，沙棘木蠹蛾雌蛾在特定时间（20：00～0：00）释放性信息素，且22：00时释放量最大，对雄蛾引诱作用最强。此项研究将为进一步深入探讨其性信息素提供依据。

Biological activity of female sex pheromone extracted from gland of Plolcocerus hippoopnaecotus Hua was studied by electroantennographic （EAG） analyses, and was validated in wind-tunnel and field trapping trials. Results showed that sex pheromone was released in particular time （20 ： 00-0 ： 00） and reached the maximum at 22 ： 00, having the strongest attractive effects to male moths. The conclusion provide the scientific basis for the further study of the sex pheromone of H. hi ppoophaecolus.
