Identification Symptoms

  • The grubs damage the stem or crown by feeding on soft tissues
  • In case of severe infestation, the inner portion of trunk is completely eaten and full of rotting fibres.
  • The holes are seen on the stem with chewed up fibres protruding out.
  • Reddish brown liquid can be seen oozing out from the hole.
  • In case of young palms the top withers, while in older palms the top portion of trunk bends and ultimately breaks at the bend (wilting).
  • The gnawing sound produced by feeding grubs will be audible.
  • In the advanced stage yellowing of the inner whorl of leaves occur.
  • The crowns fall down or dry up later when palm is dead.
