Abstract
Simulated recreation areas were established in the Cherokee Wildlife Refuge in eastern Oklahoma in an effort to evaluate various integrated procedures for control of Amblyomma americanum (L.) in recreational areas. Six 1-acre plots were replicated 3 times and received one of the following treatments: (1) mechanical clearing of all undergrowth and enough of the larger vegetation to allow 70-80% sunlight penetration; (2) mechanical clearing with the addition of an acaricide; (3) mechanical clearing with the addition of a herbicide; (4) application of an acaricide to existing vegetation; (5) application of a herbicide to existing vegetation; or (6) no treatment. Rabon®(2-chloro-1(2,4,5-trichlorophenyl) vinyl dimethyl phosphate) 75% wettable powder, was used as the acaricide and applied at 1 lb toxicant per acre in the test plots. The herbicide used was 2,4,5-T, OS applied at the recommended rate. The order of treatment effectiveness was: mechanical clearing plus an acaricide, acaricide only, mechanical clearing plus a herbicide, herbicide only, and clearing only. The acaricide-treated plots were most effective on a short-term basis, but the herbicide-treated plots had the added features of decreasing animal utilization and thereby reducing the number of possible hosts present in the area.
