建立了一个综合的计算机模型，用于模拟牛的微小牛蜱(Boophilus microplus(Canestrini))和环状牛蜱(B.annulatus)的种群动态。该模型是确定性的，基于每周时间步长的动态生命表。该模型模拟了环境温度、饱和亏、降水量、牧场类型、牛的类型和牛的密度等主要环境变量对牛蜱种群动态的影响。模型的总体效度是通过比较模拟和观测的年标准雌蜱密度/宿主/天来建立的。B.Microplus人口使用澳大利亚昆士兰两个地点的每周天气数据进行了一系列年份的比较。当使用澳大利亚7个地点和美洲23个地点的历史天气时，该模型还产生了初始人口增长率、世代时间和3年人口密度的可接受值。该模型为牛蜱传播巴贝斯虫的研究提供了一个框架，可用于研究控制技术的效果和制定更有效和环境可接受的牛蜱根除策略。
A comprehensive computer model was developed for simulation of the population dynamics of the cattle ticks, Boophilus microplus (Canestrini) and B. annulatus (Say). The model is deterministic and based on a dynamic life table with weekly time steps. The model simulates the effects of major environmental variables, such as ambient temperature, saturation deficit, precipitation, type of pasture, type of cattle, and cattle density on Boophilus cattle tick population dynamics. General validity of the model is established by comparing simulated and observed yearly densities of standard female ticks/host/day. B. microplus population comparisons were made for a series of years using weekly weather data from two locations in Queensland, Australia. The model also produced acceptable values for initial population growth rate, generation time, and 3-yr population density when historical weather at 7 locations in Australia and 23 locations in the Americas were used. This model provides a framework for the study of Babesia transmission by Boophilus ticks, and can be used to study the effects of control technologies and to develop more efficient and environmentally acceptable eradication strategies for Boophilus ticks.
