Strategic tick control in Burundi.

Strategic tick control is an attempt to control ticks and reduce losses in animal production due to tick infestations while decreasing the cost for this control. Tick control is understood as a necessity to achieve maximum animal production from animals raised in tick-infested areas. At the same time, it has become difficult to justify intensive, year-round tick control for local breeds and their crosses. The increasing costs of acaricides, maintenance of the infrastructures, salaries for personnel, etc. have created a tick control programme where the benefits may not be adequate to justify the expense. This has been the case in Burundi. This programme with adequate participation from the cattle owners of Burundi and organizational support from government personnel can help solve this economic problem. The strategic programme reduces the period of tick control to four months each year. Once optimal participation is achieved, this period can probably be reduced to three months (Kaiser et al., 1988). The period of treatment corresponds to when there is maximal feeding activity of adult female ticks on the bovine population within a certain region. Cattle should be treated once each week throughout the four-month period in order to prevent female tick engorgement (based on the life cycle of R. appendiculatus). This will greatly reduce the number of female ticks which are available to recycle the population of ticks in the participating area. At the same time, a certain population of ticks must be maintained in order to assure contact between the cattle, ticks, and tick-borne diseases of this particular region.(ABSTRACT TRUNCATED AT 250 WORDS)
