硬蜱是肉牛体外最主要的寄生虫与媒介节肢动物。据估计,仅美国每年因硬蜱吸血引起牛肉损失量为4.1kg/头,肉牛生产企业年损失量超过7 000万美元。本文讨论硬蜱引起肉牛年生产的经济损失与使用计算机发展蜱类IPM的策略,所模拟的因素包括经济的、生物的、宿主管理、草场轮换与化学防治等,作者并据计算机模拟提出评价损害的指标与综合管理的方法与策略 Ixodes ticks are the most important parasites and vector arthropods in vitro in beef cattle. It is estimated that the annual loss of beef in the United States alone is 4.1 kg per head due to blood-borne ticks and the annual loss of beef cattle producers exceeds 70 million U.S. dollars. This paper discusses the economic losses caused by ixodid-induced beef cattle production and the strategy of using computer to develop ticks IPM. The simulated factors include economic, biological, host management, pasture rotation and chemical control. The author also proposed to evaluate the damage according to computer simulation Indicators and integrated management methods and strategies
