梨圆蚧,Quadraspidiotus Pernicious(Comstock)是对果林危害较大的害虫。该虫的性信息素包括三个组分:3-亚甲基-7-甲基-7-辛烯-1-醇丙酸酯(1)、(2Z)-3,7-二甲基-2,7-辛二烯-1-醇丙酸酯(2)和(2E)-3,7-二甲基-2,7-辛二烯-1-醇丙酸酯(3)。据报道这些组分具有几乎同等的引诱活性。我们开展该虫性信息素的合成研究,以探索进行生物防治的途径。
Pear scale, Quadraspidiotus Pernicious (Comstock) is a pest harmful to fruit trees. The sex pheromone of this insect includes three components: 3-methylene-7-methyl-7-octen-1-ol propionate (1), (2Z) Octadien-1-ol propionate (2) and (2E) -3,7-dimethyl-2,7-octadien-1-ol propionate (3). These components are reported to have almost the same attractant activity. We carry out the synthesis of the insect sex pheromone to explore ways to biological control.
