Abstract

A 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.

Résumé

En vue de réprimer l’invasion des régions nordiques par le termite souterrain Reticulitermes flavipes (Kollar), un projet en collaboration entre le Laboratoire des produits forestiers des E.-U. et celui du Canada a été inauguré en 1966 pour l’étude de l’efficacité d’un appât traité à l’insecticide. Il s’agit d’une méthode employée en vue de l’éradication de foyers d’infestation relativement vastes.

Les appâts de bois dégradé par le champignon Lenzites trabea (Pers.) Fr., avec ou sans revêtement de poison (insecticide Mirex), ont été installés dans des lots expérimentaux à Oxley, Ontario. Nous avons enregistré une suppression rapide de l’activité des termites. Nous poursuivrons les observations et les travaux en vue de déterminer si le poison peut prévenir l’expansion souterraine des colonies et aussi éliminer les infestations locales par le dit termite.
