Two new host records for Centrodoraitalica Ferrière (Hymenoptera, Aphelinidae) from eggs of Tettigoniidae (Orthoptera, Ensifera) in northeastern Italy.

The egg parasitoid Centrodoraitalica Ferrière is reported for the first time from sentinel eggs of two species of Tettigoniidae (Orthoptera), Pachytrachisgracilis (Brunner von Wattenwyl) and Eupholidopteraschmidti (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 .
