An unequivocal observation on the damage caused by the grubs of Grey weevil; Myllocerus discolor (nr.) Boheman, to the roots of Teak seedlings in Maharashtra has been reported. The infested seedlings succumbed to the injury and died. Period and pattern of infestation, incidence level and description of grub, pupa, and adult with their possible control measures have been discussed. This is the first evidence of curculionid, M. discolor grubs infesting on forest tree host.
