Short communication: Amitraz treatments do not increase the frequency of mutations in the β2-adrenergic octopamine receptor in Varroa destructor: a field study in Central Spain.

Abstract excerpt

The ectoparasitic mite Varroa destructor is a major threat to Apis mellifera colonies. Beekeepers use acaricides such as amitraz for control, but resistance has been reported, possibly linked to mutations in the Octβ2R gene. This study examined the frequency of these mutations in Varroa populations from two management systems: organic (oxalic acid treatment) and conventional (amitraz treatment). DNA was extracted...
