The species is widely spread throughout Europe and Northern Russia ( Yu et al. 2012; Zwakhals and van Achterberg 2017). In 1937, 96 adults of C. borealis  were released in U.S.A. (Connecticut) from Europe, to control the European pine shoot moth, Rhyacionia buoliana  (Denis & Schiffermüller, 1775) ( Lepidoptera  Tortricidae  ), but the species has not become established ( Dowden 1962, Bartlett et al. 1978).

Host range.

Yu et al. (2012) report 19 host species associated with C. borealis  , belonging to the families Coleophoridae  (8 species), Tortricidae  (4 species, L. botrana  is not into the list), Psychidae  , Yponomeutidae  , Eriocraniidae  , Gelechiidae  , Gracillariidae  , Simaethidae  (one species each) and on the weevil Anthonomus pomorum  (Linnaeus, 1758) ( Coleoptera  Curculionidae  ).

Ecological role.

In three years of sampling on Daphne gnidium  , Nuzzaci and Triggiani (1982) obtained three specimens of this parasitoid from larvae of L. botrana  (identified by K. Horstmann). This is the only record on EGVM so far.

Taxonomic notes.

Campoplex borealis  is the species that gives its name to a " borealis  " species-group of the genus Campoplex  ( Horstmann 2012). With the name of C. borealis  were indicated at least six different species ( Horstmann 2012), morphologically very similar and mainly characterized by their host preferences. Right now, eight species are included in this species-group: C. borealis  (Zetterstedt, 1838), C. jaeckhi  (Bauer, 1936), C. psammae  (Morley, 1915), C. punctipleuris  Horstmann, 1980, C. serratellae  Horstmann, 2012, C. caloptiliae  Horstmann, 2013, C. tussilaginis  Horstmann, 2013 and Campoplex linosyridellae  Horstmann, 2016. They are mainly related to Coleophoridae  and Gelechiidae  ; one species, C. caloptiliae  , lives on Gracillariidae  , while a second species close to C. psammae  lives on Psychidae  ( Horstmann 1980, 2012, 2013, Shaw et al. 2016). Horstmann (1985) does not mention EGVM among the hosts of C. borealis  , despite a male and a female collected by Nuzzaci and Triggiani are in his collection in ZSM.
