( Lepidoptera, Tortricidae).  Host range. This koinobiont egg-larval endophagous parasitoid feeds on various species of economically important moths, especially belonging to the family Tortricidae. Yu et al. (2012)provide a list of sixty-seven host species. In the vineyards it has been also associated to Paralobesia viteanaand Eupoecilia ambiguella.  Ecological role. As already highlighted by Bagnoli and Lucchi (2006), in Tuscany this parasitoid is usually present at low density in all the three generations of Lobesia botrana. In Veneto it has never been obtained by larvae of the first generation, but reached a maximum rate of parasitism of 4.4% in the second generation and 2.7% in the third generation. In Sardinia it was obtained only from first generation larvae of EGVM living on Daphne gnidium, with a parasitism rate of 3.7%.  Figure 3. Ascogaster quadridentataWesmael 1835.
