The invasion of , spotted-wing drosophila, across Europe and the US has led to economic losses for berry and cherry growers, and increased insecticide applications to protect fruit from damage. Commercial production relies heavily on unsustainable use of conventional toxic insecticides. Non-toxic insecticide strategies are necessary to alleviate the disadvantages and non-target impacts of toxic conventional insecticides and improve Integrated Pest Management (IPM). A novel food-grade gum deployed on dispenser pads (GUM dispensers) was evaluated to mitigate crop damage in five commercial crops and nine locations. Trials were conducted at a rate of 124 dispensers per hectare in cherry, wine grape, blueberry, raspberry, and blackberry in California and Oregon, USA during 2019 and 2020. The majority of trials with the food-grade gum resulted in a reduction of egg laying in susceptible fruit. In some cases, such damage was reduced by up to 78%. Overall, results from our meta-analysis showed highly significant differences between GUM treatments and the untreated control. Modeling simulations suggest a synergistic reduction of damage when used in combination with Spinosad (Entrust SC) insecticide. These data illustrate commercial value of this tool as a sustainable alternative to manage populations within a systems approach.
斑翅果蝇入侵欧洲和美国，给浆果和樱桃种植者造成了经济损失，为保护果实免受损害，杀虫剂的使用量也有所增加。商业生产严重依赖对传统有毒杀虫剂的不可持续使用。为减轻有毒传统杀虫剂的弊端和非目标影响并改善综合虫害管理（IPM），无毒杀虫剂策略必不可少。一种部署在分配垫上的新型食品级树胶（树胶分配器）在五种商业作物和九个地点进行了评估，以减轻作物损害。2019年和2020年期间，在美国加利福尼亚州和俄勒冈州，以每公顷124个分配器的速率，在樱桃、酿酒葡萄、蓝莓、树莓和黑莓上进行了试验。大多数使用食品级树胶的试验都减少了易受害果实上的产卵量。在某些情况下，这种损害减少了多达78%。总体而言，我们的荟萃分析结果显示，树胶处理与未处理对照之间存在极显著差异。建模模拟表明，与多杀霉素（安打悬浮剂）杀虫剂联合使用时，对斑翅果蝇损害有协同降低作用。这些数据表明了该工具作为一种可持续替代方法，以系统方法管理斑翅果蝇种群的商业价值。
