| Abstract:
Wild or feral populations of Vaccinium are commonly found adjacent to commercial fields. These native populations can act as a source of pest pressure, since most of the disease organisms that invade cultivated Vaccinium also attack wild species. We have been studying the spread of two virus diseases, blueberry shoestring (BBSSV) and blueberry leaf mottle (BBLMV). BBSSV is found in many wild populations of V. angustifolium and V. corymbosum in Michigan and at a few other locations in the eastern US and Canada. Disease spread between the wild and cultivated populations may be common, because the aphid vector of BBSSV, Illinoia pepperi, invades both cultivated and native plants. BBLMV is also present in wild populations of V. corymbosum, V. angustifolium and V. myrtilloides in Michigan. Spread of BBLMV is likely between wild and cultivated Vaccinium, as leaf mottle disease is pollen transmitted and bees move readily between native and domesticated fields. | |
