Abstract
Subterranean termites, Coptotermes curvignathus (Holmgren) is the most important termite which caused economic losses is very high in Indonesia and other tropical regions. In this studies, the feeding preferences of the subterranean termite, C . curvignathus for decayed wood by some wood rotting fungus were examined to determine whether the presence of wood rotting fungus could alter the relative preference of termites for these decayed wood. The study is expected to find phagostimulant compounds for the development of termite control by baiting techniques. The results showed that, the decayed wood process by the P. o streotus fungi higher rate of decay compared with other fungus (10.86 + 2.21%), S. commune (10.29 + 1.86%), P. c hrysosporium (6.19 + 1.56%) and Dacriopinac sp (5.02 + 0.95%). Meanwhile, the lowest rate of decay by the T. v ersicolor fungi (4.25 + 0.93%). Based on the results of this stuies the feeding preference of C. curvigntahus on decayed wood by the P. ostreatus fungi and S. c ommune fungi is higher than the decayed wood by other wood rotting fungus.
Highlights
Subterranean termites an economically important insect for causing huge economic losses
The results showed that weight loss due to decay by the fungus S. commune, Dacriopinac sp, P. ostreotus, T. versicolor and P. chrysosporium in a row is 10.29 ± 1.86%, 5.02 ± 0.95%, 10.86 ± 2.21%, 4.25 ± 0.93% and 6.19 ± 1.56%, respectively
Weight loss rate is low due to decaying of wood by fungi and fungal of Dacriopinac sp and T. versicolor presumably due to low tolerance compared to other fungal species of wood ekstratif substances in test samples
Summary
Subterranean termites an economically important insect for causing huge economic losses. Subterranean termites, especially those from the subfamily Rhinotermitinae (Coptotermes spp) are found to be attacking buildings in urban area [1] and buildings in rural or suburban areas [1, 2]. According several of studies [3,4,5,6] that, subterranean termite Coptotermes sp was the most dominant pest species found infesting about 70% attacking on building. It cause economic loss million US dollars every year. In Indonesia, according Kuswanto et al [10] economic loss due to termite attack is estimated to reach more than 1.6 billion US dollars per year
