First record of resistance to flumethrin in a varroa population from Uruguay
Varroa destructor is the most serious parasitic mite that infests the honey bee Apis mellifera. Different treatments with systemic acaricides are applied to control, but due to the intensive use of these chemicals, resistance to organophosphates and pyrethroids has developed worldwide. Most of the r...

Most of the resistance episodes have been registered for fluvalinate, and only in a few cases has flumethrin resistance been reported.

High infestation levels of V. destructor are continuously detected in colonies of A. mellifera after treatments with flumethrin.

Furthermore, the LC50 baseline levels for flumethrin in two Uruguayan populations were determinated. The LC50 for flumethrin for the population from Colonia Department was 3.8 μg/Petri dish, which means an increase of 34.5 fold when compared to the corresponding baseline, suggesting the development of resistance. These results are the first report of resistance to flumethrin in V. destructor in Uruguay, and extend the knowledge of acaricide resistance in the country. © 2016 National Scientific and Technical Research Council (CONICET).
