Faba Bean Pests

  • no serious insect pests of faba bean are known to occur in western Canada
  • blister beetle, grasshopper, leafhopper and aphid can occasionally be found in faba bean, but rarely at economically damaging levels
  • lygus can cause quality losses – they move into faba bean after other crops have matured and if numbers are high enough, can cause loss in grade (pin holes in the seed coat)
  • blister beetle and grasshopper feed on faba bean shoots and buds – damage is usually localized to the area being fed on
  • leafhopper cause damage by transmitting aster yellows while feeding on faba bean
  • aphid is usually found on the stems and underside of leaves and, like leafhopper, is more of a concern because they can transmit viruses while feeding on faba bean
