Laboratory and field evaluation for the resistance of commonly used woods against Coptotermes heimi (Wasmann).

The current study was conducted to evaluate the resistance of four wood species (Azadirachta indica, Pinus roxberghii, Dalbergia sissoo and Populus deltoides) against subterranean termite species Coptotermes heimi by choice and no choice field and laboratory trials. Of these four wood species P. roxberghii and D. sissoo proved to be most resistant to termite attack. Taken together these results we can conclude that D. sissoo is the least preferred and P. deltoides is the most preferred wood by the C. heimi. The data obtained from the field choice and no-choice the woods are arranged in order of preference DS>PR>AI>PD whereas in laboratory choice and no-choice trials the order of preference was PD>AI>PR>DS.
