Evaluation of Datura stramonium and Nicandra physalodes as reservoirs of Tomato severe rugose virus and whiteflies
Plant Pathology 69 (3), 569-575
Abstract: Tomato severe rugose virus (ToSRV) is the most important begomovirus transmitted and spread by the whitefly Bemisia tabaci in tomato crops in Brazil. Cultural practices are being adopted, along with insecticides, for controlling this virus. However, little is known about the importance of weeds in the pathosystem, which can contribute to the failure of these practices. This work aimed to evaluate the role of Datura stramonium and Nicandra physaloides as alternative hosts of ToSRV and verify the viral influence on the biological performance of Bemisia tabaci Middle East-Asia Minor 1 (MEAM1) and Mediterranean (MED) cryptic species. N. physaloides was a better alternative host for ToSRV when combined with MEAM1 whiteflies, while D. stramonium was mostly a good host for whitefly reproduction. Viral infection improved MEAM1 performance on both host plants but affected MED performance negatively. These data suggest that both weeds can be of some importance for the pathosystem, and their control should be included in management programmes.
