本文采用单个性信息素腺体分析技术、高效毛细管色谱、色质联用、触角电位、微化学反应和田间试验得知水稻三化螟性信息素有16:Ald(Ⅰ)、(Z)-9-16:Ald(Ⅱ)和(Z)-11-16:Ald(Ⅲ)等三个组份。据单个雌蛾性信息素腺体的分析结果表明:腺体中三个组份的比例平均为18.8(Ⅰ):27.1(Ⅱ):54.1(Ⅲ)(%)。按上述三元组份比例配制的诱芯在田间显示强烈的引诱作用,单盆每天最高诱捕数达45头雄蛾,平均每天诱捕15.8头雄蛾。 相似文献

The natural sex pheromone of the yellow rice borer, Scirpophaga incertulas is known to consist of 3 components: 16: Ald (Ⅰ), (Z)-9-16: Ald (Ⅱ) and (Z)-11-16: Ald (Ⅲ) by using single sex pheromone gland technique, high performance capillary CC, GC-MS, EAG, micro-chemical reaction as well as field trapping tests. Analysis of single sex pheromone gland showed that the precise ratio of the 3 components is 18.8 (Ⅰ): 27.1 (Ⅱ): 54.1 (Ⅲ) (%). The septura lure made according to the above precise blending showed strong attractancy in the field trapping tests. Maximun catch of a trap was 45 males/ day in the first generation in Guangxi Zhuang Autonomous Region. The average catch per day was 15.8 males. 相似文献
