RNA interference (RNAi), an innovative molecular technology already used against viruses (e.g. DWV), could also be useful for varroa control.
A new study from the University of Wellington, New Zealand, reported effective mite control using varroa-specific RNAi (vadescana), administered through feeding at two different doses. Both doses reduced mite populations compared to the untreated control, with levels comparable to those achieved using synthetic miticides. The survival rate of the treated colonies was also significantly higher than that of the control group (45% versus 7.5%).
RNAi confirms its effectiveness against Varroa, opening up a new strategy for mite control.
