Discovery ofTrichoferus campestris(Coleoptera: Cerambycidae) in Ontario, Canada and first host record in North America

Abstract

Introductions of some forest invasive alien species result in important economic, environmental, and ecological impacts. One approach used by the Canadian Food Inspection Agency to improve the detection of these species is to collect logs from trees in declining health at high risk sites of introduction and to incubate them to obtain insects, if present. Trichoferus campestris (Faldermann) (Coleoptera: Cerambycidae) adults emerged, and live larvae were extracted, from one of two logs taken from a dying Norway maple, Acer platanoides Linnaeus (Sapindaceae), in Mississauga, Ontario, Canada. In its native range, eastern Asia, this beetle is polyphagous, however, in North America there is no host record despite numerous interceptions of larvae in wood packaging material and captures of adults at various post-entry sites. An examination of the feeding damage caused by T. campestris in that maple suggests this insect is not a primary pest of trees in Ontario.

Survey tools and demographic parameters of SlovakianAgrilusassociated with beech and poplar

“…The introduction and establishment of alien wood-boring insects pose a systemic risk to the health and long-term sustainability of forest and urban trees (Haack, 2006). Surveillance tools to detect non-indigenous wood-boring insects include semiochemical-baited traps, rearing insects from logs collected from high-risk areas, and visual inspection of trees (Douglas et al, 2013;Bullas-Appleton et al, 2014. There is much need to develop survey tools for the detection of Agrilus species because of the the high invasiveness risk in this taxon and the cryptic nature of infestation.…”

Attraction of ambrosia beetles to ethanol baited traps in a Slovakian oak forest

“…Ethanol baited funnel traps are utilized in the USA and Canada to monitor various bark and ambrosia beetles (Coyle et al 2005;Humble et al 2010;Noseworthy et al 2012;Bullas-Appleton et al 2014). Conversely, ethanol baited traps are not used to detect or monitor ambrosia beetles in Slovakia or many other European countries.…”

“…In contrast, ethanol baited traps are commonly used to assess temporal and spatial patterns of ambrosia beetles, for monitoring ambrosia beetles in ornamental nurseries, and they are used in various detection programs in the USA and Canada (Humble 2001;Sweeney et al 2007;Miller & Rabaglia 2009;Reding et al 2010;Ranger et al 2011;Noseworthy et al 2012;Bullas-Appleton et al 2014).…”

Citizen monitoring of invasive species: wing morphometry as a tool for detection of alien Tetropium species

“…The Canadian Food Inspection Agency also incubates and rears insects from sections of trunks cut from trees that show signs of stress or insect infestation at sites at high risk of exotic wood borers, for example near ports or industrial parks in larger cities (Bullas‐Appleton et al. ). These trapping surveys generate large numbers of captured specimens that need to be sorted and identified by taxonomists.…”

“…Most national programmes for survey and detection of invasive bark and wood borers use traps baited with pheromones, for example New Zealand (Brockerhoff et al 2006b), the United States (Rabaglia et al 2008;USDA-APHIS 2011) and Canada (CFIA 2013). The Canadian Food Inspection Agency also incubates and rears insects from sections of trunks cut from trees that show signs of stress or insect infestation at sites at high risk of exotic wood borers, for example near ports or industrial parks in larger cities (Bullas-Appleton et al 2014). These trapping surveys generate large numbers of captured specimens that need to be sorted and identified by taxonomists.…”
