Abstract

Standardized laboratory testing of wood and wood-based products against subterranean termites in Indonesia (SNI 01.7207-2006) (SNI) has no requirement for the inclusion of a comparative reference species of wood (reference control). This is considered a weakness of the Indonesian standard. Consequently, a study was undertaken to identify a suitable Indonesian species of community wood that could be used as a reference control. Four candidate species of community woods: Acacia mangium, Hevea brasiliensis, Paraserianthes falcataria and Pinus merkusii were selected for testing their susceptibility to feeding by Coptotermes formosanus. Two testing methods (SNI and the Japanese standard method JIS K 1571-2004) were used to compare the susceptibility of each species of wood. Included in the study was Cryptomeria japonica, the reference control specified in the Japanese standard. The results of the study indicated that P. merkusii is a suitable reference species of wood for inclusion in laboratory tests against subterranean termites, conducted in accordance with the Indonesian standard (SNI 01.7207-2006).

Highlights

Indonesia has extensive community forests which produce a diverse range of wood species
In these forests, four species of wood are abundant in both quantity and future supply: Acacia mangium, Paraserianthes falcataria, Hevea brasiliensis and Pinus merkusii
The Indonesian standard SNI 01.7207-2006 does not specify the use of a selected reference control that will enable comparison of data obtained by different researchers

Summary

Introduction

Indonesia has extensive community forests which produce a diverse range of wood species. It is important that the experimental design of such laboratory tests include a suitable reference material (control). This enables the researcher to compare the performance of the candidate material/s under test with that of a known reference control. The inclusion of a suitable reference control in the laboratory test can be used to compare mortality of termites with those that are exposed to the candidate materials. The choice of an appropriate wood species to serve as a reference control is most important for the conduct of comparative laboratory tests on the termite-resistance of both untreated and preservative-treated woods
