Pheromone-baited traps have been widely used in integrated pest management programs, but their economic value for growers has never been reported. We analyzed the economic benefits of long-term use of traps baited with the citrus fruit borer Gymnandrosoma aurantianum sex pheromone in Central-Southern Brazil. Our analysis show that from 2001 to 2013 citrus growers avoided accumulated pest losses of 132.7 million to 1.32 billion USD in gross revenues, considering potential crop losses in the range of 5 to 50%. The area analyzed, 56,600 to 79,100 hectares of citrus (20.4 to 29.4 million trees), corresponds to 9.7 to 13.5% of the total area planted with citrus in the state of São Paulo. The data show a benefit-to-cost ratio of US$ 2,655 to US$ 26,548 per dollar spent on research with estimated yield loss prevented in the range of 5-50%, respectively. This study demonstrates that, in addition to the priceless benefits for the environment, sex pheromones are invaluable tools for growers as their use for monitoring populations allows rational and reduced use of insecticides, a win-win situation.
信息素诱捕器已广泛应用于害虫综合治理项目中,但从未有过关于其对种植者经济价值的报道。我们分析了在巴西中南部长期使用柑橘果蛀蛾(Gymnandrosoma aurantianum)性信息素诱捕器的经济效益。我们的分析表明,在2001年至2013年期间,考虑到潜在作物损失在5%至50%之间,柑橘种植者避免了总计1.327亿美元至13.2亿美元的害虫造成的收入损失。所分析的面积为56,600至79,100公顷柑橘园(2040万至2940万棵树),占圣保罗州柑橘种植总面积的9.7%至13.5%。数据显示,每投入1美元用于研究,收益成本比分别为2655美元至26548美元,估计可防止5%至50%的产量损失。这项研究表明,除了对环境有不可估量的益处外,性信息素对种植者来说也是非常宝贵的工具,因为使用它们来监测虫口数量可以合理且减少杀虫剂的使用,这是一种双赢的局面。
