枣镰翅小卷蛾性信息素通讯系统

采用单个雌蛾性信息素腺体分析技术对枣镰翅小卷蛾Ancylis sativa Liu雌蛾性信息素的组分和组分间的精确比例进行了测定，结果表明，枣镰翅小卷蛾雌蛾的性信息素系统由二个顺反异构体组分组成，即反-9-十二碳烯醋酸酯(E9-12∶Ac)和顺-9-十二碳烯醋酸酯(Z9-12∶Ac)组成，E9-12∶Ac与Z9-12∶Ac的比例为6.5∶3.5；雌蛾产生和释放性信息素具有时辰节律性，在光周期14L∶10D、温度为21℃时，性信息素产生的高峰期为进入黑暗期6.5 h；不同日龄雌蛾产生的性信息素有差异，1日龄最低，2日龄最高，3～5日龄居中，不同日龄雌蛾产生的性信息素组分间的比例无显著差异；对3个世代雌蛾产生的性信息素的量及组分间的比例的研究表明，越冬代含量最高，为(10.1±7.0)ng/头，第2代为(9.5±4.6)ng/头，第1代仅为(1.4±1.0)ng/头，3个世代性信息素组分间的比例无显著差异，在63.1%～64.3%(E)范围内。

THE SEX PHEROMONE COMMUNICATION SYSTEM OF ADULT JUJUBE LEAFROLLER ANCYLIS SATIVA LIU

In this paper, the titre and precise ratio of multi-components of Ancylis sativa Liu sex pheromone were determined by using analytical technique of single sex pheromone gland. The results showed that: (1)the female sex pheromone contained two isomers, i.e. E9-12∶Ac and Z9-12∶Ac, (2) the sex pheromone production of females had a diel periodicity. The female moths began to produce sex pheromone at the onset of the scotophaes and the quantity increased gradually. Pheromone production peak occurred at the 6.5 hour of the second scotophase, (3) the pheromone titres released by females of various generations are different. The pheromone titre released by females of the overwintering generation or the second generation was much higher than that of the first generation, but the ratios of the 2-isomeric components in different generations were the same.
