Summary of responses of simulated southern cattle fever tick, Rhipicephalus (Boophilus) microplus, populations to dipping cattle in acaricide every 3 weeks for 9 months when the indicated percentages of the cattle are treated. a Probabilities of eliminating host-seeking larvae from the simulated pasture. Blue bars and red bars represent results from the versions of the model with k = 4200 and k = 7300, respectively. Ranges in the number of weeks after the first acaricide application to elimination with k = 4200 (b) and k = 7300 (c). No bars indicated eliminations did not happen under the specific treatments. Results are based on 10, 5-year, Monte Carlo simulations of each treatment level
