 The state's Department of Agriculture has said that the apple maggot threatens "Washington's iconic apple industry, as well as many of our other fruit crops".The establishment of reproducing populations of the apple maggot within Washington would have a devastating impact on the state's apple industry resulting from the potential loss of export markets.Each year, the Washington state Department of Agriculture deploys apple maggot traps to a selection of sites in the state with between 5,500 to 8,500 traps deployed annually.
