The Asian giant hornet () was recently detected in western British Columbia, Canada and Washington State, United States. are an invasion concern due to their ability to kill honey bees and affect humans. Here, we used habitat suitability models and dispersal simulations to assess potential invasive spread of We show are most likely to establish in areas with warm to cool annual mean temperature, high precipitation, and high human activity. The realized niche of introduced populations is small compared to native populations, suggesting introduced populations could spread into habitats across a broader range of environmental conditions. Dispersal simulations also show that could rapidly spread throughout western North America without containment. Given its potential negative impacts and capacity for spread, extensive monitoring and eradication efforts throughout western North America are warranted.
亚洲大黄蜂（）最近在加拿大不列颠哥伦比亚省西部和美国华盛顿州被发现。由于它们能够杀死蜜蜂并影响人类，因此被视为入侵物种的担忧。在这里，我们使用栖息地适宜性模型和扩散模拟来评估的潜在入侵传播。我们表明，在温暖到凉爽的年平均温度、高降水和高人类活动的地区，最有可能建立。与本地种群相比，引入种群的实际生态位很小，这表明引入种群可能会传播到更广泛的环境条件下的栖息地。扩散模拟还表明，如果不加以控制，可能会迅速蔓延到整个北美西部。鉴于其潜在的负面影响和传播能力，有必要在整个北美西部进行广泛的监测和根除工作。
