The expansion of the worldwide pet trade has increased the invasion risks from not only exotic pet animals, but also live feeder organisms for predatory pet animals. Here, we report the first field record of a tropical live feeder cockroach, Blaptica dubia (Serville, 1838), in the central part of Japan. This widely traded feeder insect may be able to colonize temperate zones because they were estimated to survive through two winters in Japan at temperatures close to the upper limits of their critical thermal minimum. Further field observations are needed to understand the behavior of this species in the wild and predict the risk of invasion in temperate zones.

在日本的温带地区引入的宠物饲养蟑螂Blaptica dubia（Serville，1838）（Blattidae，Blaberinae）的首次野外记录

全球宠物贸易的扩展不仅增加了外来宠物的入侵风险，还增加了掠食性宠物的活体饲养生物的入侵风险。在这里，我们报告了日本中部热带活食蟑螂Blaptica dubia（Serville，1838年）的第一个现场记录。这种广为交易的饲养昆虫可能能够在温带定居，因为据估计它们在日本的两个冬季都可以在接近其临界最低热量上限的温度下存活两个冬天。需要进一步的野外观察，以了解该物种在野外的行为并预测在温带地区入侵的风险。
