Reservoir Weed Hosts of Tomato Spotted Wilt Virus

Abstract

Surveys were made in Hawaii''s major vegetable production areas including Waianae on Oahu, Kula Maui, and Waimea on Hawaii to determine important reservoir plants of tomato spotted wilt virus (TSWV). More than 9,000 plant samples were collected and analyzed for TSWV by enzyme-linked immunosorbent assay. Forty-four plant species representing 16 families were found infected with TSWV. Twenty-five species are considered important reservoirs of the virus. Twenty-four new TSWV host recordings are identified.
