RESISTANCE OF DAMPWOOD TERMITES TO PRESERVATIVE-TREATED WOOD

The effects of three wood preservatives on dampwood termites (Zootermo psis augusticollis Hagen) and their gut protozoa were studied. Chromat ed copper arsenate and ammoniacal copper zinc arsenate were associated with absence of termite feeding and higher termite and protozoa morta lity; low levels of polyborate affected termites more slowly. Dampwood termites were generally more sensitive to preservatives than were sub terranean termites examined in previous studies, which suggests that d ampwood termite damage can easily be avoided through the use of preser vative-treated wood.
