New approaches in the development and management of drugs used in ectoparasite control

This review examines the present trend in ectoparasite control towards application techniques designed to give prolonged persistence and efficacy. The consequences of this approach for resistance management and current developments in relation to the resistance problem are considered. Likely leads and new concepts in the search for alternative drugs are discussed. In particular the role of molecular biology in advancing knowledge and providing new techniques in this field is explored.
