The shift to more environmentally sensitive agricultural practices over the last several decades has changed farmland landscapes worldwide. Changes including no-till and retaining high biomass mulch has been coincident with an increase in rodent pests in South Africa, India, South America and Europe, indicating a possible conflict between conservation agriculture (CA) and rodent pest management. Research on effects of various crop management practices associated with CA on pest rodent population dynamics is needed to anticipate and develop CA-relevant management strategies.
During the Australian 2020-2021 mouse plague, farmers used postharvest stubble management practices, including flattening and/or cutting, to reduce stubble cover in paddocks to lessen habitat suitability for pest house mice. We used this opportunity to assess the effects of both harvest and stubble management on the movement and abundance of mice in paddocks using mouse trapping and radio tracking. We found that most tracked mice remained resident in paddocks throughout harvest, and that mouse population abundance was generally unaffected by stubble management.
Recent conversions to CA practices have changed how pest house mice use cropped land. Management practices that reduce postharvest habitat complexity do not appear to reduce the attractiveness of paddocks to mice, and further research into new management strategies in addition to toxic bait use is required as part of an integrated pest management approach. © 2023 The Authors.

过去几十年，向更环保的农业实践的转变改变了全球农田景观。包括免耕和保留高生物质覆盖物在内的变化，与南非、印度、南美洲和欧洲啮齿动物害虫的增加同时发生，表明保护农业（CA）和啮齿动物害虫管理之间可能存在冲突。需要研究与 CA 相关的各种作物管理实践对害虫啮齿动物种群动态的影响，以便预测和制定与 CA 相关的管理策略。
在澳大利亚 2020-2021 年的鼠灾期间，农民采用了收获后秸秆管理措施，包括压扁和/或切割，以减少牧场中的秸秆覆盖，降低害虫家鼠的栖息地适宜性。我们利用这个机会，通过老鼠诱捕和无线电跟踪，评估了收获和秸秆管理对牧场中老鼠移动和丰度的影响。我们发现，大多数被追踪的老鼠在收获期间都留在牧场中，并且老鼠种群的丰度通常不受秸秆管理的影响。
最近向 CA 实践的转变改变了害虫家鼠对作物土地的利用方式。减少收获后栖息地复杂性的管理措施似乎并没有降低牧场对老鼠的吸引力，作为综合虫害管理方法的一部分，除了使用有毒诱饵外，还需要进一步研究新的管理策略。© 2023 作者。害虫管理科学由 John Wiley & Sons Ltd 代表化学工业协会出版。
