Managed Pollinator CAP Coordinated Agricultural Project The War Against Varroa

摘要

Varroa mites have been a significant and consistent problem for honey bee colonies in the United States for the past 25 years. By using hard and soft chemicals and IPM practices, beekeepers have attempted to keep mite levels down and colonies healthy.Much effort has been devoted to study the life cycle, behavior and control strategies for Varroa destructor, and this information has led to the development of new management techniques beekeepers use for this pest. However, for the most part, many of these new practices have not resulted in adequate control or are impractical due to excessive labor, time, and/or cost of application and this has pushed some beekeepers to investigate alternative methods and products. One strategy has been to return to the old varroacide, amitraz which is currently registered for use in Canada and Europe in the form of impregnated plastic strips, under the trade name Apivar~R.
