建立了一个综合的计算机模型，用于模拟北美犬蜱（ADT）的种群动态。该模型模拟的主要环境变量，如环境温度，饱和赤字，栖息地的种类，和主机密度，在生态系统中的ADT人口动态与小型哺乳动物作为主机的未成年蜱和中型哺乳动物或家犬作为主机的成年蜱。通过比较弗吉尼亚州、马里兰州和马萨诸塞州一系列年份的模拟和实际人口密度，建立了该模型的一般有效性，并将每年的实际每周天气数据作为模型输入。该模型使用ADT已知地理范围内11个地点和该范围外3个地点的历史平均天气数据，为初始种群增长率和世代时间以及现实的平衡种群密度和季节性活动模式提供了可接受的值。该模型可以作为一个框架，额外的建模工作，以模拟落基山斑疹热的传播，并研究各种策略的ADT人口的管理。
A comprehensive computer model was developed for simulation of the population dynamics of the American dog tick (ADT), Dermacentor variabilis Say, in North America. The model simulates the effects of major environmental variables, such as ambient temperature, saturation deficit, kind of habitat, and host density, on ADT population dynamics in ecosystems with small mammals as hosts for immature ticks and medium-sized mammals or domestic dogs as hosts for adult ticks. General validity of the model was established by comparisons between simulated and actual population densities for a series of years at locations in Virginia, Maryland, and Massachusetts using actual weekly weather data for each year as a model input. Using historical-average weather data for 11 locations within the known geographic range of ADT and 3 locations outside this range, the model produced acceptable values for initial population growth rate and generation time, as well as realistic equilibrium population densities and seasonal activity patterns. This model can be used as a framework for additional modeling efforts to simulate the transmission of Rocky Mountain spotted fever and to study various strategies for management of ADT populations.
