Distribution.

The species is present in Europe and North Africa; in Asia it is recorded up to Japan (for more details see: Yu 1997-2012 and Cabi 2016a). Ascogaster quadridentata was introduced in North America and New Zealand for the biological control of Cydia pomonella L. ( 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 viteana and 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%.
