299 First Infestation by lncisitermes minor of a Canadian Building (lsoptera: Kalotermitidae) by J. K. Grace, 1 G. M. Cutten,2 R. H. Scheffrahn,3 and D. K. McE. Kevan4 ABSTRACT An extensive infestation of /ncisitermes minor (Hagen) Kalo- termitidae) was discovered in the interior wood framing of a home in Toronto, Ontario, Canada, In the fall of 1989. Alate flights had occurred in October 1989, and probably the preceding year, indicat- ing that the termites had been active in the structure for several years. This is the first known infestation by /. minor of a building in Canada, and the first established drywood termite infestation reported in eastern Canada. INTRODUCTION Wood-inhabiting beetles and termites are easily transported in infested wood products. In a mobile society, introductions of such exotic species are difficult to prevent. Between 1935 and 1938, the eastern subterranean termite, Reticulitermesflavipes (Kol- lar) (lsoptera: Rhinotermitidae) was introduced by ship to Toronto (Urquhart 1953) and has since become well established throughout southern Ontario. In a dramatic extension of its range, a well established R. flavlpes infestation was discovered in Winnipeg in 1987 (Anonymous 1987a, 1987b, 1989; Grace 1989, Kevan 1990) • Although climatic constraints may limit the natural distribu- tion of such species, the domiciliary environment is conducive to their survival, once introduced. 1Department of Entomology, University of Hawaii, 3050 Maile Way, Honolulu, HI 96822, USA 2Hazardous Contaminants Coordination Branch, Ministry of the Envir- onment, 135 St. Clair Avenue West, Toronto, Ontario M4V 1P5, Canada 3Ft.
