Abstract
Seasonal densities of free-living Amblyomma americanum (L.) were determined for vegetatively managed and unmanaged areas in 5 Oklahoma parks during 1978 and 1979. A Dry Ice® method was used to sample for adults and nymphs, and a cloth drag method was used for larvae. Vegetative management consisted of partial removal of overstory, removal of understory, and frequent mowing to maintain the height of grasses at < 15 cm. Overall controls obtained through vegetative management for adult females, adult males, nymphs, and larvae were 78, 76, 93, and 84%, respectively.
