ABSTRACT Stoats (Mustela erminea) were introduced to New Zealand to control rabbits in the 1880s and their impact on native birds has been devastating. Stoat control needs to be ongoing if some iconic species are to survive on the mainland. A re-setting toxin device (Spitfire) has been developed that fires a paste containing para-aminopropiophenone (PAPP) on to the belly of stoats as they pass through a tunnel. When the stoats groom the paste from their fur, they ingest the toxin. A pilot field trial of the device was undertaken in the Blue Mountains, West Otago in late 2013. The probability of detecting stoats using camera traps declined by between 76.6% and 89.8% within 6 weeks following the deployment of the Spitfire; however, by this time, some of the Spitfires had malfunctioned. Spitfires could be a useful additional control tool for stoats, but they need to be re-engineered to be made more durable for field conditions.

一种新的白鼬毒素输送装置——来自现场试验的结果

摘要 白鼬（Mustela erminea）在 1880 年代被引入新西兰以控制兔子，它们对本地鸟类的影响是毁灭性的。如果一些标志性物种要在大陆生存，就需要持续控制白鼬。已经开发出一种重置毒素装置 (Spitfire)，当白鼬通过隧道时，它会将含有对氨基苯丙酮 (PAPP) 的糊状物发射到白鼬的腹部。当白鼬从它们的皮毛上梳理糊状物时，它们会摄入毒素。该设备于 2013 年底在西奥塔哥的蓝山进行了现场试验。在部署喷火战斗机后的 6 周内，使用相机陷阱检测到白鼬的概率下降了 76.6% 至 89.8%；然而，此时，一些喷火战斗机出现了故障。喷火战斗机可能是白鼬的一个有用的附加控制工具，
