Faszly Rahim and A. B. Idris and A. S. Sajap and K. Norman and W. Mohd. Basri (2003) The pattern of infestation by subterranean termite Coptotermes curvignathus holmgren (lsoptera:Rhinotermitidae) on young oil palm peat. [Proceedings Paper]
Abstract
External and internal symptoms of damage by the subterranean termite, Coptotermes curvignathus (Rhinotermitidae: Coptotermitinae) on palms aged 3-6 years in an ex¬felled jungle were studied. Five levels were categorized: (]) Palms with tunnelling traces and patched excavations near the meristemic region. Crown still green and spear erect. Period: 1-3 weeks after full encapsulation of trunk with peat mudwork (2) Excavations of the meristemic region occurred. Spear yellowing or broken at the base. Period: 4-6 weeks (3) Excavation developed where tunnelling from root base was also seen. Foliage started yellowing where breakages of the second to fifth fronds also occur. Secondary infection hastened death especially to immature palms. Palms were considered unrecoverable. Period: 2-4 months. (4) Excavations might advance in mature palms where the two excavated regions fused. Internal centre of the palms were hollowed. Palms dried up sequentially from leaflet tips towards rachises and from top and lower fronds towards the middle. Period: 5-10 months. (5) Palms were completely hollow, fronds and crown collapsed. Period: 12 months and later. Hence, the termite attack is serious and some control suggestions are discussed.
