Abstract

The egg parasitoid Centrodora italica Ferrière is reported for the first time from sentinel eggs of two species of Tettigoniidae (Orthoptera), Pachytrachis gracilis (Brunner von Wattenwyl) and Eupholidoptera schmidti (Fieber). In Italy, only two hosts of this parasitic wasp are known, one of which is a tettigoniid species. Exposure of sentinel eggs represented a useful method to detect new host associations of this parasitoid species that can search for their host’s eggs in the ground. The parasitoids were identified by comparing our specimens with those of the type series, and the original description of C. italica.
