The effects of climate change and shifting consumer preferences for tropical/subtropical mango fruits have accelerated their greenhouse cultivation in South Korea, which has consequently exacerbated the risk of unexpected or exotic insect pest outbreaks. This study used the pest risk analysis (PRA) of greenhouse-cultivated mangoes provided by the Animal & Plant Quarantine Agency in Korea to evaluate the potential of ethyl formate (EF) fumigation as a new pest management strategy against the yellow tea thrips (), which is considered a surrogate pest in the thrips group according to the PRA. The efficacy and phytotoxicity of EF were evaluated in greenhouse-cultivated mango tree (Irwin variety) and post-harvest mango fruit scenarios. EF efficacy ranged from 6.25 to 6.89 g∙h/m³ for lethal concentration time (LCt) and from 17.10 to 18.18 g∙h/m³ for LCt, indicating similar efficacy across both scenarios. Application of 10 g/m³ EF for 4 h at 23 °C could effectively control (100% mortality) without causing phytotoxic damage to the greenhouse-cultivated mango trees, while post-harvest mango fruit fumigation with 15 g/m³ EF for 4 h at 10 °C showed potential for complete disinfestation of without compromising fruit quality.
气候变化以及消费者对热带/亚热带芒果偏好的转变，加速了韩国芒果的温室种植，这也因此加剧了意外或外来害虫爆发的风险。本研究利用韩国动植物检疫局提供的温室栽培芒果的有害生物风险分析（PRA），评估甲酸乙酯（EF）熏蒸作为一种针对黄蓟马的新害虫管理策略的潜力，根据PRA，黄蓟马被视为蓟马类群中的替代害虫。在温室栽培芒果树（欧文品种）和采后芒果果实的情况下，评估了EF的功效和植物毒性。对于致死浓度时间（LCt），EF的功效范围为6.25至6.89 g∙h/m³，对于LCt，功效范围为17.10至18.18 g∙h/m³，表明两种情况下功效相似。在23°C下以10 g/m³的EF处理4小时，可以有效控制黄蓟马（死亡率100%），且不会对温室栽培的芒果树造成植物毒性损害，而在10°C下以15 g/m³的EF对采后芒果果实熏蒸4小时，显示出在不影响果实品质的情况下完全灭虫的潜力。
