Under laboratory conditions, rangeland plants can harbor vesicular stomatitis virus (VSV) and pass the virus to grazing grasshoppers.
Scientists selected 14 rangeland plant species that grasshoppers eat and exposed the plants to VSV in a laboratory setting. In the lab, several species harbored viable virus for up to 24 hours. The scientists then exposed two plant species to VSV and fed them to grasshoppers 24 hours later. The grasshoppers became infected. These results support the hypothesis that grasshopper-cattle-grasshopper transmission of VSV is possible.
