FIELD: biotechnology.
SUBSTANCE: described is a group of inventions involving a method of reducing a viral load in a Varroa destructor mite, a method of suppressing viral replication in a mite Varroa destructor and a method for reducing the susceptibility of a bee to a disease caused by a bee virus. Said methods include providing a Varroa destructor mite containing an effective amount of at least one double-stranded RNA (dsRNA), containing a nucleic acid sequence identical or complementary to a sequence of at least 21 adjacent nucleotides of the bee virus gene. In one embodiment, said composition contains a dsRNA mixture consisting of 2, 3, 4, 5, 6, 7, 8, 9 or 10 different dsRNAs.
EFFECT: invention extends the range of agents for reducing viral load in Varroa destructor mite.
