Eupelmus annulatus Nees, 1834

Comment. Eupelmus annulatus , in common with other species of Eupelmus , is polyphagous, but its host range is uncertain because taxonomic confusion renders many published host records unreliable. Gibson (2011), in a revision of North American Eupelmus , cites an association with Elachistidae Agonoxeninae, Tortricidae and Erebidae Lymantriinae in Lepidoptera , Curculionidae and possibly Scolytinae in Coleoptera , and Diprionidae and Cynipidae (rarely, Europe) in Hymenoptera , parasitism of these phytophagous species being either primary or secondary through Braconidae and Ichneumonidae . European material of E. annulatus , using Gibson’s interpretation of the morphospecies, has been reared from Psychidae (Lepidoptera) in Italy ( Apterona sp.) and England ( Dahlica triquetrella (Hübner, 1813)) . It is also quite frequently obtained from dead or dying wood ( Corylus in England, Malus in Poland, Ulmus in France and Poland) in company with Scolytinae and other beetles, and from Crataegus bark with Tortricidae ( England) . Gibson & Fusu (2016) provided a list of hosts based on the material examined which basically includes those quoted by Gibson (2011).

A female E. annulatus , the only specimen found during the present study, emerged after overwintering from a dry fruit of A. albus albus which was still attached to a flower spike when collected on 3.x. 2007 in France (Vienne, Châtellerault) (in RAPC).
