Agronomic measures for a decrease of the Amblyomma variegatum tick populations

Abstract

Some pasture and herd exploitation methods could be applied successfully to decrease cattle infestation with Amblyomma variegatum. Soil purification can be obtained by a temporary over-grazing followed by a “trap” animal treatment. This purification can be maintained by limiting grazing to a 6 p.m., 6 a.m. period, when very few engorged ticks drop from hosts and infest pastures and when very few flat ticks are active and go and fix upon the hosts. On the opposite, nymph and overall Amblyomma variegatum adult longevity is such that infestation decrease by animal rotation practice on pasture is an irrelevant method.
