A new mutation in the octopamine receptor associated with amitraz resistance in Varroa destructor.

Our data indicate the association of the F290L mutation in the octopamine receptor with resistance to amitraz in Spanish populations of V. destructor. Determining the frequency of mutant mites in apiaries may be important for predicting the efficacy of amitraz treatment in the field and would help design appropriate resistance management. © 2024 The Author(s).
