Field populations of Amblyomma americanum (L.) were tested in North Carolina, Florida, and Oklahoma with various formulations of permethrin, NRDC 161 ((S)-[cyano(3-phenoxyphenyl) methyl] cis -(+ )-3-(2,2 ,-dibromoethenyl)-2, 2-dimethylcyclopropanecarboxylate), carbaryl, diazinon, and chlorpyrifos. Probit analyses indicated that effective doses to achieve a 6 weeks 95% control level for permethrin, NRDC 161, and carbaryl were 0.9,0.07, and 8.2 kg AI/ha, respectively. Control with 3 formulations of diazinon at 1.12 kg AI/ha ranged from 71–92%. Differences in rainfall between North Carolina and Florida apparently had little influence on control by diazinon. Chlorpyrifos, at 0.56 ka AI/ha produced a control level of ca. 79%. A method for the laboratory testing of potential acaricides is described. The field-tested materials ranged from 10–0.26X relative to the chlorpyrifos standard in these laboratory tests.
