The aim of this work was to test the efficacy of winter–spring control strategies against Rhipicephalus (Boophilus ) microplus (Canestrini, 1888) (Ixodida: Ixodidae) in an area highly favourable for its development in Argentina. Control schemes using three or four annual applications of synthetic acaricides were evaluated. Furthermore, the dynamics of the non‐parasitic phases of R. microplus were analysed to provide a framework for the application of pasture spelling as a tool for tick control. The treatment schemes provided appropriate levels of efficacy against R. microplus and also prevented the occurrence of the major peak in abundance of this tick in autumn. A significant overall effect against R. microplus can be achieved when the control strategies tested in this study are applied within the area most ecologically favourable for this tick in Argentina. Analysis of the dynamics of the non‐parasitic phase of R. microplus indicates that the spelling period required to achieve a significant reduction of larvae in pastures fluctuates between 12 and 17 weeks if spelling is initiated in spring or early summer, but between 20 and 28 weeks if spelling is started in late summer, autumn or winter.

在阿根廷非常有利于其发展的地区，采取管理策略以尽量减少使用合成化学杀螨剂来控制牛tick Rhipicephalus（Boophilus）microplus（Canestrini，1888）。

这项工作的目的是在阿根廷最有利于该地区发展的地区，测试冬春季控制策略对小头头hip（Boophilus）microplus（Canestrini，1888）（Ixodida：Ixodidae）的功效。评估了每年使用三到四次合成杀螨剂的控制方案。此外，分析了R. microplus的非寄生虫阶段的动力学，为应用牧场拼写作为as控制工具提供了框架。该治疗方案提供了适当水平的抗微小芽孢杆菌功效，并且还防止了在秋季出现此壁虱丰度的主要高峰。对当在这项研究中测试的控制策略应用于对阿根廷for虫最生态有利的地区时，可以实现微小micro。对R. microplus非寄生虫阶段动态的分析表明，如果春季或夏季初开始进行拼写，则使草地上的幼虫显着减少所需的拼写时间在12至17周之间波动，但在20至28之间如果在夏末，秋季或冬季开始拼写，则需要数周的时间。
