SUBTERRANEAN TERMITE STUDIES IN SOUTHERN ONTARIO

Abstract

AbstractA cooperative project between Forest Products Laboratories in the United States and Canada, initiated in 1966 to study the control effectiveness of an insecticide-treated termite attractant, is reported. It represents a bait method of control being developed to eradicate relatively large pockets of infestation.Wooden bait blocks decayed by Lenzites trabea (Pers.) Fr., which attracts termites, with and without poison coating (Mirex insecticide) were installed in experimental plots at Oxley, Ont. An abrupt suppression of termite foraging occurred in plots where insecticide was used. Observations will be continued and work extended to determine whether the poison will prevent subterranean expansion of colonies and to assess its degree of effectiveness in eliminating localized pockets of infestation.
