Development of a new approach of pasture management to control Rhipicephalus microplus infestation

Despite several decades of chemical control, the cattle tick Rhipicephalus microplus remains an important constraint for cattle farmers. The regular use of chemicals has led to the development of tick strains that are multi-resistant to acaricides. New methods of tick control are being developed and combined in integrated tick management programs. Grazing management is one part of these control methods. However, until now, grazing management consisted essentially of resting pastures for 4 to 5 months. This amount of time is generally sufficient to allow for natural tick larvae mortality to occur, but this method often compromises the quality of forages, which is less than optimal at the time of arrival of the animals in the paddock. In this paper, we propose a new approach to pasture management-based tick control that optimizes forage production. It is based on tick development biological parameters, herd management and strategic treatments. This approach was tested for 2 years on two farms raising tick-susceptible European breeds of cattle under tropical conditions. The number of chemical treatments decreased respectively by 82.9% and 70.9%. This cost-effective approach may prove useful in decreasing the number of acaricidal treatments on farms facing high tick loads.
