Amitraz Resistance in French Varroa Mites: Not Related to a Single Mutation
The findings revealed regional occurrences of amitraz resistance, with a less severe decrease in treatment efficacy compared to other pesticides. Notably, the genetic analysis showed that the previously identified mutation at position 260 may not directly cause amitraz resistance, questioning the role of this genetic marker and suggesting a more complex resistance mechanism. The study can be viewed in its entirety at this…
