No oophagous parasitoid was found. From larvae of A. rubi, 3 species of Hymenoptera emerged: the braconids Triaspis aciculatus (Ratz.) and Bracon immutator Nees and the pteromalid Spilomalus quadrinota (Walk.). T. aciculatus was the main limiter of this curculionid, with parasitization rates varying from 2.5 to 68.8, according to different situations. Parasitization rates of the other two species were ranging from 1.4 to 15.3 for B. immutator and from 1.0 and 28.0 for S. quadrinota. This is the first report of T. aciculatus and S. quadrinota as limiters of A. rubi.
