Agrilus sulcicollis

Lacordaire in Boisduval & Lacordaire, 1835

European oak borer

Agrilus sulcicollis, commonly known as the European oak borer, is a metallic wood-boring in the . to Europe and Northern Asia, it has been to North America, with confirmed records in southern Ontario, Canada, and the northeastern United States. The is associated with oak trees and is one of nine non-native Agrilus species established in North America.

Identification

Agrilus sulcicollis can be diagnosed among North Agrilus by morphological characters detailed in taxonomic literature. It is illustrated in Jendek & Grebennikov (2009) to facilitate recognition. The species belongs to a group of Agrilus associated with oak , though specific distinguishing features from North American oak-associated species require examination of detailed morphological characters.

Habitat

Oak woodlands and forests. Associated with oak trees (Quercus spp.) as larval .

Distribution

to Europe (widespread across most countries), Northern Asia (excluding China), and parts of North Africa (Algeria, Morocco, Tunisia). to North America with confirmed records in southern Ontario, Canada, and Michigan and New York, USA.

Host Associations

Quercus spp. - larval Primary ; implied by 'European oak borer'
Carpinus betulus - larval Hornbeam; secondary
Castanea spp. - larval Chestnut; secondary

Ecological Role

Wood-boring whose tunnel in living or recently dead woody plants. As an in North America, it represents a potential forest pest, though its impact relative to other Agrilus species (such as A. planipennis, the emerald ash borer) appears limited based on current records.

Human Relevance

Agrilus sulcicollis is one of nine non- Agrilus established in North America. While it has been detected in North America, it has not achieved the notoriety of A. planipennis (emerald ash borer) as a major forest pest. and accurate identification are important for tracking its spread and potential impact on oak-dominated forests.

Similar Taxa

Agrilus planipennisBoth are Agrilus in North America, but A. planipennis attacks ash (Fraxinus) rather than oak and has caused far more extensive damage
Other North American native Agrilus speciesMany Agrilus occur on oak; accurate identification requires examination of morphological details and reference to diagnostic literature
Agrilus cuprescens, A. cyanescens, A. derasofasciatus, A. hyperici, A. pilosovittatus, A. sinuatus, A. subrobustusThese are the other eight non- Agrilus established in North America, all of which require careful morphological examination to distinguish from A. sulcicollis

More Details

Taxonomic note

Agrilus sulcicollis was described by Lacordaire in 1835. The Agrilus is one of the largest genera in the animal with nearly 4,000 described .

Invasion history

First reported in North America from southern Ontario, Canada. The has since been recorded in Michigan and New York, USA. Its introduction and date are not well documented in the available literature.
