- Direct exposure of Philaenus to Metarhizium brunneum reduces its survivorship.
- M. brunneum successfully colonises the host plant and reduces survival of Philaenus.
- Philaenus reaches the xylem faster on M. brunneum-colonised plants.
- Xylem sap ingestion by Philaenus is similar on non-colonised and colonised plants.
- Contact with M. brunneum does not alter the egestion pattern of Philaenus.
