Abstract
A new method for testing acaricides against ticks on dogs is described. The tests involved natural populations of lone star ticks, Amblyomma americanum (L.), which infested beagle dogs in the field in woodlots of eastern Oklahoma. The described method has the advantage of using natural populations and infestations; this procedure eliminates the need for rearing ticks and artificially infesting hosts. The method was used from April to July in 1982 and 1983 to compare the effectiveness of 11 commercially available acaricides that were applied as dips to experimental dogs in field trials against nymphal and adult A. americanum. The residues from the dips lost effectiveness in killing >50% of the attached ticks from <4 days (pyrethrins) to 22 to 29 days (chlorfenvinphos).Keywords
