Israeli vine growers have been reluctant to adopt the mating disruption technique for control of the European vine moth, Lobesia botrana Den. & Schiff. Since the chemically controlled honeydew moth, Cryptoblabes gnidiella Mill., coexists with the European vine moth, growers have maintained that the use of mating disruption would fail to bring about a significant reduction in pesticide use. In this study, the efficacy of mating disruption techniques against C. gnidiella was tested, as well as the effect of these methods on pesticide use and damage to clusters when the method was employed against both of the pests in wine grapes. Comparisons were made between plots treated with (1) L. botrana mating disruption pheromone, (2) L. botrana and C. gnidiella mating disruption pheromones and (3) control plots. A significant difference in the number of clusters infested with the developmental stages of the moths was seen between pheromone-treated plots and controls, while no such difference was observed between plots treated with one versus two pheromones. A similar pattern was observed in the number of insecticide applications; the greatest number of applications was used in control plots, followed by plots treated with L. botrana mating disruption pheromone and by plots treated with pheromones against both pests, in which no pesticides were applied.
以色列的葡萄种植者一直不愿采用交配干扰技术来防治欧洲葡萄蛾，即葡萄小卷蛾（Lobesia botrana Den. & Schiff.）。由于与欧洲葡萄蛾共生的化学防治对象蜜露蛾（Cryptoblabes gnidiella Mill.），种植者坚持认为使用交配干扰技术无法显著减少农药使用量。在本研究中，测试了交配干扰技术对蜜露蛾的防治效果，以及在酿酒葡萄中同时使用这些方法防治两种害虫时，它们对农药使用和葡萄串损伤的影响。对分别用（1）葡萄小卷蛾交配干扰信息素、（2）葡萄小卷蛾和蜜露蛾交配干扰信息素处理的地块与（3）对照地块进行了比较。在信息素处理地块和对照地块之间，观察到受蛾类发育阶段侵害的葡萄串数量存在显著差异，而在使用一种信息素与两种信息素处理的地块之间未观察到此类差异。在杀虫剂施用次数上也观察到类似模式；对照地块施用次数最多，其次是使用葡萄小卷蛾交配干扰信息素处理的地块，而使用两种害虫信息素处理的地块未施用任何农药。
