Wild pigs (Sus scrofa) are a destructive invasive species throughout many regions of the world. In 2018, a field evaluation of an early prototype of a sodium nitrite (SN) toxic bait in the United States revealed wild pigs dropped large amounts of the toxic bait outside the pig‐specific bait stations while feeding, and thus subsequent hazards for non‐target animals. We modified the SN‐toxic bait formulation, the design of the bait station, and the baiting strategy to reduce dropped bait. We tested the modifications in Queensland, Australia (December 2018), Alabama, USA (August 2019), and Texas, USA (March 2020) under differing climatic and seasonal conditions for one night.

改良的亚硝酸钠有毒饵料对野猪的功效和风险

野生猪（Sus scrofa）是世界许多地区的破坏性入侵物种。2018年，在美国对亚硝酸钠（SN）有毒诱饵的早期原型进行了现场评估，结果显示野猪在喂食时将大量有毒诱饵掉落到特定于猪的诱饵站外，从而对非诱饵造成后续危害目标动物。我们修改了SN毒性诱饵配方，诱饵站的设计以及减少掉落诱饵的诱饵策略。我们在澳大利亚昆士兰州（2018年12月），美国阿拉巴马州（2019年8月）和美国德克萨斯州（2020年3月）在不同的气候和季节条件下测试了一晚的修改。
