梨小食心虫[Grapholitha molesta(Busck)],又名东方果蛾,是一种世界性的果树害虫,主要为害梨、桃、李、杏和苹果。 1969年,Roelofs等报告,梨小食心虫性外激素的主要成份是顺-8-十二碳烯醋酸酯。后来又发现在这种人工合成的性外激素中加入少量反式异构体,能显著地提高诱蛾效力。 1975年5月,我们合成了梨小食心虫性外激素,并从6月至9月在北京地区进行了田间试验,重点研究了诱蛾活性与顺、反异构体比例的关系,也对性外激素与糖醋水的诱蛾效果,以及粘胶诱捕器与水瓶诱捕器的诱蛾效果等进行了比较。现将试验的初步结果整理如下。
Grapholitha molesta (Busck), also known as oriental fruit moth, is a worldwide pest of fruit trees, mainly pears, peaches, plums, apricots and apples. In 1969, Roelofs et al. Reported that the main component of the pest mite pheromone was cis-8-dodecene acetate. Later found in this synthetic sex hormone added a small amount of trans-isomer, can significantly improve the effectiveness of the moth. In May 1975, we synthesized the pest mite pheromone and conducted a field experiment in Beijing from June to September. The study focused on the relationship between the moth’s activity and the cis and trans isomer ratio, Gynostemma and the sweet and sour water traps the moth effect, as well as viscose traps and water bottle traps the effect of the moth were compared. The preliminary results of the trial are now organized as follows.
