银花尺蠖(学名待定)是金银花的主要害虫之一。在金银花的产区平邑县等地为害十分严重。为了有效地探索其防治途径,刘清琪等对银花尺蠖越冬代和第一代雌蛾性信息素粗提物进行过性诱试验,说明雌蛾分泌的性信息素对雄蛾有明显的引诱作用。1980年8月份,为了取得较多的性信息素粗提物,以便进行分离提纯,进而鉴定结构和人工合成,为此,我们在山东省平邑县郑城公社东岭,对银花尺蠖第二代成虫的性信息素作了进一步研究。初步确定了性信息素提取的适宜时间和大量提取所适用的有机溶剂。并对
Silver flower ulnar (scientific name to be determined) is one of the main pests of honeysuckle. In the production area of honeysuckle, Pingshuo County and other places are very serious. In order to effectively explore its prevention and control methods, Liu Qingqi and others conducted a sexually induced test on the overwintering winter spurs and the crude female sex pheromone extracts of female moths, indicating that the sex pheromone secreted by female moths has obvious attraction to male moths. . In August 1980, in order to obtain more crude extracts of sex pheromones in order to carry out separation and purification, and then to identify structure and artificial synthesis, for this purpose, we are in Dongling, Zhengcheng Community, Pingyi County, Shandong Province, and Second-generation adult sex pheromones were further studied. Initially determined the appropriate time for the extraction of sex pheromone and a large amount of organic solvent suitable for extraction. And
