Abstract: Oil palm plantations
in West Kalimantan are located in an area dominated by peat soils. This
condition makes oil palm trees vulnerable to subterranean termite attack.
Coptotermes curvignathus Holmgren currently has become one of major key pest of
oil palm. These termites attack the oil palm trunk, crown, fronds and fruits.
Current practice of Termite control in oil palm is by direct spraying chemical
pesticides, but this type of treatment proves uneconomical and hostile to the
environment. In addition, chemical sprays are ineffective due tothe termite
nest is below ground and the pesticide does not reachthe termites inside the
nest. Therefore a new paradigm, such as baiting systemwhich the objective for
termite colony elimination are needed to control termites in oilpalm
plantation. This study aimed to evaluate the effectiveness of Copton 0.5 RB
containing the active ingredient hexaflumuron 0.5% to control Coptotermes
curvignathus in oil palm plantation at mature oil palm. Four blocks of an oil
palm plantation with severe termite damage was chosen as test site. In each
block consisted of four oil palm trees and one bait was place at one tree
within each block. Monitoring was conducted every seven days for one month, and
after that bait consumption and colony elimination were analyzed. The results
showed average bait consumption value was 96.87%.The bait consumption
activities start from seven days after installation. 1st monitoring showed good
palatability that the termites consumed 13 from 16 baits. The consumption began
to decline at the end of the fourth week. It was assumed that the baits were
eliminatethe termite colony. The decline in termite attack in the oil palm
trees was first observed with drying of the termite shelter tubes and by no
termites inside the oil palm fronds. It is concluded that Copton0.5RB
(hexaflumuron 0.5%) is effective for colony elimination of
Coptotermescurvignathusin oil palm plantations.
