EVALUATION OF CHLORFLUAZURON IN CONTROLLING THE SUBTERRANEAN TERMITE COPTOTERMES CURVIGNATHUS (ISOPTERA: RHINOTERMITIDAE) IN INDONESIA

We evaluated the effectiveness of a bait formula containing the active ingredient chlorfluazuron in controlling the subterranean termite Coptotermes curvignathus which infests houses in Jakarta. Two types of aggregation devices (‘stations’), namely, in-ground stations (IGS) and above-ground stations (AGS) were applied. IGS complete with timber interceptors lining the inner station wall and a wood block in the centre was installed around the perimeter of the houses to monitor the termite activity. The number of stations installed was adjusted to the space available. Stations infested by termites were then filled with the bait matrix after the wood block was removed. The AGS (with bait matrix) were installed directly on the points of termite attack found in the houses. Stations were inspected every two weeks to determine the vigour of the termite colony based on the termite population infesting stations, ratios of soldiers:workers and the amount of bait consumption. Results showed that most bait matrix was totally consumed and the ratio of soldiers:workers initially increased and finally the termite infestation ceased. Colony elimination took about six to eight weeks after baiting. Use of the AGS was considered more practical for properties with active termites. However, a combination of treatments using the two station types is recommended.
