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.
