Strategic treatment of pastured beef cattle with acaricides: effect on populations of the lone star tick (Acari: Ixodidae)
Application of acaricides to beef cattle at 10 day intervals between late March and early July 1980 resulted in an 86.7 and 84.3 percent, respectively, in populations, of parasitic and free-living larvae of Amblyomma americanum (L.) during August and September 1980. Numbers of nymphs in August and September 1980 were reduced 72.7 percent (parasitic) and 95.6 percent (free living) as a result of the treatment regimen, whereas the numbers of parasitic and free living adults in spring 1981 were reduced 46.2 and 80.7 percent, respectively
