Abstract

The varroa mite (Acari: Mesostigmata: Varroidae) has developed resistance to the 2 major miticides (fluvalinate and coumaphos) registered for control of this invasive pest of bees (Hymenoptera: Apidae) in the United States. Comparative studies on miticide toxicity with and without the synergists piperonyl butoxide and formamidine indicated that enhanced metabolism by mixed-function oxidases and altered target site were the major mechanisms of resistance to organophosphorus and pyrethroid insecticides in varroa mite populations of northern Florida.

 

Sumario

El ácaro Varroa (Acari: Mesostigmata: Varroidae) ha desarrollado resistencia a 2 acaricidas principales (fluvalinato y cumafós) registrados para el control de esta plaga invasora de las abejas (Hymenoptera: Apidae) en los Estados Unidos. Estudios comparativos sobre la toxicidad de los acaricidas con y sin las sinergistas butóxido de piperonilo y formamidina indicaron que el aumento del metabolismo por oxidasas de función mixta y sitio del enfoque alterado fueron los principales mecanismos de resistencia a los organofosforados y piretroides en poblaciones de ácaros Varroa del norte de Florida.
