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
