Trichoferus campestris

Associated with woody vegetation in both native and introduced ranges. In North America, has been detected in suburban parks and urban environments, with traps in Tilia trees capturing significantly more adults than those in Quercus. Develops in living and cut wood of various hardwood species.

Native to eastern Asia including China, North Korea, South Korea, Japan, Mongolia, and eastern Russia. Introduced and established in North America (USA and Canada, first detected 1997 in New Jersey), and multiple European countries including Germany, Austria, Belgium, France, Italy, Poland, Romania, UK, and others. Range expanding westward in Europe and within North America.

Adult activity is unimodal with peak abundance in early July in Minnesota (around 650 degree-days, base 10°C). Active during summer months in temperate regions.

Polyphagous wood-feeder. In native Asia, feeds on multiple tree species. In North America, documented hosts include Acer platanoides (Norway maple), Juglans nigra (black walnut), Malus domestica (apple), and Acer saccharum (sugar maple). Oviposition and larval development occur more readily on Juglans nigra and Malus domestica than on Acer saccharum or Pinus strobus.

• Acer platanoides - larval hostFirst confirmed host record in North America; declining tree in Mississauga, Ontario
• Juglans nigra - larval hostPreferred for oviposition and larval development in host choice experiments
• Malus domestica - larval hostPreferred for oviposition and larval development; oviposition higher on cankered than uncankered wood
• Acer saccharum - larval hostSupports oviposition and development less readily than Juglans or Malus
• Pinus strobus - larval hostSupports oviposition and development less readily than preferred hardwood hosts

Eggs laid on cut branches or woody material. Larvae develop within wood, with development benefiting from cold exposure during overwintering. Adults emerge from infested wood. Can complete development in dry wood, facilitating establishment in transported wood products.

Adults are attracted to pheromone-baited traps. Females show oviposition preference for certain host species and for cankered over uncankered apple wood. Has been observed taking over active nests of other wasps in related cerambycid species.

Wood-boring beetle that develops in hardwood trees and cut wood. Not considered a primary pest of living trees in Ontario based on feeding damage examination. Serves as host for parasitoid wasp Solenura ania (Pteromalidae).

Invasive species of phytosanitary concern. Subject to detection efforts by Canadian Food Inspection Agency through incubation of logs from declining trees at high-risk introduction sites. Intercepted in wood packaging material. Potential pest of live trees, wood furniture, and orchard trees.

• Other Trichoferus speciesGenus-level characters require examination of antennal structure and body proportions; T. campestris distinguished by specific antennal segment ratios and elytral pubescence pattern
• Other Hesperophanini cerambycidsTribe members share elongate body form and antennal characteristics; species identification requires detailed examination of genitalia and punctation patterns
