Plant vascular systems can transport entomopathogens from the soil into plant tissues, but it is not fully explored whether other soil dwelling entomopathogens utilize this pathway for movement. Research showed that baculoviruses, a common entomopathogen and bioinsecticide, may not be translocated through plant vascular pathways to induce lethal infection in insects.
Plant vascular systems can translocate the entomopathogen Bacillus thuringiensis from the soil into plant tissues. However, whether other soil dwelling entomopathogens utilize plant vascular tissue for movement has not yet been fully explored. We used Spodoptera frugiperda multiple nucleopolyhedrovirus (SfMNPV) to evaluate whether baculoviruses, a common entomopathogen and bioinsecticide, can be transported through the plant vascular pathways of Zea mays. We found that our treatments did not allow a sufficient virus translocation into the plant to induce a lethal infection in insects, which was confirmed by a molecular analysis. While other entomopathogens translocate, baculoviruses may not be one of them.
