Abstract:Experiments were carried out to investigate whether Potato spindle tuber viroid (PSTVd) can be transmitted intra- and inter-species from infected Solanum jasminoides to non-infected S. jasminoides and S. esculentum and from infected Brugmansia sp. to S. esculentum by Frankliniella occidentalis and Thrips tabaci by leaf sucking. The F. occidentalis experiments also included feeding on pollen prior to feeding on PSTVd-infected leaf. No thrips-mediated transmission of PSTVd was recorded. The possibility of PSTVd transmission by Apis mellifera and Bombus terrestris during their feeding/pollinating activities within ornamentals and from ornamentals to S. esculentum was included, and no bee-mediated transmission was recorded.
