Abstract
Base-line data on acaricide susceptibility in the American dog tick, Dermacentor variabilis (Say), were collected on 27 compounds tested in the laboratory. Five- to 7-week-old nymphs were exposed for 22 to 24 h to residues of acetone dilutions of technical materials on disposable glass pipettes. Effectiveness of the compounds in killing ticks ranged from an LC50 of 0.00002% for propoxur to an LC50 of 0.001% for fenthion (median) to and LC50 of 1.97% for rotenone.Keywords
