A review of insect parasitoids associated with Lobesia botrana (Denis & Schiffermüller, 1775) in Italy. 1. Diptera Tachinidae and Hymenoptera Braconidae (Lepidoptera, Tortricidae)

Abstract

Abstract

This paper is aimed to summarize the information available on the parasitoid complex of the European Grapevine Moth (EGVM), Lobesia botrana (Denis & Schiffermüller, 1775) ( Lepidoptera Tortricidae ) in Italy. The list is the result of the consultation of a vast bibliography published in Italy for almost two hundred years, from 1828 to date. This allowed the clarification and correction of misunderstandings and mistakes on the taxonomic position of each species listed.

In Italy the complex of parasitoids detected on EGVM includes approximately 90 species belonging to ten families of Hymenoptera ( Braconidae , Ichneumonidae , Chalcididae , Eulophidae , Eupelmidae , Eurytomidae , Pteromalidae , Torymidae , Trichogrammatidae , and Bethylidae ) and one family of Diptera ( Tachinidae ). This paper deals with EGVM parasitoids of the families Tachinidae ( Diptera ) and Braconidae ( Hymenoptera ). Only two species of Tachinidae are associated to EGVM larvae in Italy, Actia pilipennis (Fallen) and Phytomyptera nigrina (Meigen), whereas the record of Eurysthaea scutellaris (Robineau-Desvoidy) is doubtful. Moreover, 21 species of Braconidae are reported to live on EGVM, but, unfortunately, eight of them were identified only at generic level. Bracon mellitor Say has been incorrectly listed among the parasitoids of Lobesia botrana . Records concerning Ascogaster rufidens Wesmael, Meteorus sp., Microgaster rufipes Nees, and Microplitis tuberculifer (Wesmael) are uncertain.
