Tick control: further thoughts on a research agenda.

Tick control is a subject that has stimulated intense interest for more than a century. This article is a commentary on the research needs for tick control proposed in Peter Willadsen's recent article and it calls attention to tick control strategies that were either poorly represented or omitted from the latter. Special consideration is given to host-targeted devices to control disease vector ticks infesting wildlife, to pheromone-impregnated decoys for attracting and killing ticks in the natural environment and on hosts, and to more up-to-date advances in vaccine development.
