Abstract

Damages of building construction due to termite attacks have caused high economic losses and therefore, efforts are continuously developed to overcome the serious problem. Baiting system is one way to control termite attacks as it consists of acceptable termite food sources, combined with a slow-acting substance lethal to termites. This study was conducted to produce termite bait materials from organic waste mixtures and evaluate its effectiveness against termite attacks in the field. The termite baits were produced by mixing paper, cardboard, and degraded pine wood, combined with leaves of Melaleuca leucadendron Linn assumed to be toxic to termites. Tapioca starch was used as glue and added to the organic materials mixture before pressed at room temperature with the target density of 1.0 g/cm3. The produced baits were placed in the field with signs of heavy attacks of termites, Coptotermes sp., and observed every three days for the termite elimination. Results showed that the bait formulation enables to significantly eliminate the termite attacks with high attractant properties. However, its effectiveness was still lower than the commercial bait due to its high capacity of water absorption, indicating the importance of further research on its mixture and glue formulation.

Abstract

Information about colony fragments survival of the termite species Coptotermes curvignathus Holmgren in the laboratory is very limited. This study was conducted to determine colony fragments survival of the subterranean termite C. curvignathus Holmgren in laboratory maintenance. The test media used the Termitarium PSIH-IPB: 1999 as a glass vessel containing 4 kg of a mixture of sand and clay with 4 proportions and 4 different pH determined as treatments that would be studied for their effects on termite survival. The results showed that the proportion of the sand:clay mixture affected the survival and feeding preferences of the subterranean termite C. curvignathus Holmgren. The highest percentage of termites that survived was found in the termitarium containing a mixture of sand:clay 50:50. The highest percentage of bait wood weight loss occurred in the test media containing a mixture of sand: clay 50:50. The weight loss of bait wood is directly proportional to the termites survival.

Abstract

Wood-destroying termites are quite influential in Indonesia, and the subterranean termite Schedorhinotermes javanicus is one of them. This study was conducted to determine the feeding preferences of subterranean termites S. javanicus on tusam (Pinus merkusii) wood and the influence of their environment. The bait woods made of tusam boards were installed at the experimental site. The weight loss and consumption of bait woods were studied with three test times (one, two, three) months of burial. The subterranean termite specimens attacking the bait woods, soil characteristics, and weather at the experimental field were also identified. The results demonstrated that the average air temperature at the experimental site was 25.4 ± 0.4°C, the average air humidity reached 88.8 ± 2.4%, and the light intensity at the experimental site ranged from 175.67 lux to 3889.7 lux. The results showed that S. javanicus quite actively attacked the bait wood. This can be seen from the high weight loss (35.03%) and the wood consumption (38.78 g). The weight loss after three exposure times in the experimental field was up to 13.54%, 16.38%, and 35.03%, respectively. The wood consumption during the same experimental period reached 14.9 g, 18.25 g, and 38.78 g, sequentially. The high weight loss and the consumption of bait wood indicate the high feeding preference of the subterranean termites S. javanicus on tusam wood.

Abstract

Fast-growing species are chemically and thermally modified to improve quality. These changes affect wood’s chemical composition and surface characteristics. This study aims to analyze the durability of fast-growing teak wood that has been chemically and thermally modified. Chemical modification was carried out by impregnation using citric acid and polyethylene glycol (PEG) 400, while heat modification carried out at 150 °C. The wettability of wood was tested by measuring the contact angle with six types of liquid, aquades, toluene, glycerin, methanol, alkyd, and acrylic paint. The results showed that chemical modification treatment significantly improved the wettability of wood compared to control and heat treatment. Wood treated with citric acid and PEG 400 exhibits a lower contact angle, indicating increased liquid absorbency. Conversely, heat treatment increased the contact angle value making the wood more hydrophobic. Alkyd showed better wettability than acrylic paints, possibly due to their lower viscosity values. This suggests that chemical modification more effectively improves wood coating adhesion.
