Roland Quitugua delivered two damaged coconut crowns he had cut from trees in [village?] to UOG for diagnosis on 26 Feb 2008. Aubrey Moore, UOG entomologist, and George Wall, UOG plant pathologist examined the crowns agreed that the damage was caused by new Guinea sugarcane weevil, Rhabdoscelus obscurus (Boisduval). Seven adults and 2 grubs of this species were found along with numerous tunnels in the stem and petioles, and holes on leaves. On Guam, this pest is mainly a pest of ornamental palms and betelnut. However, it occasionaly causes severe damage to coconut palms.
