Dr. Ferrer-Suay is a Hymenopteran taxonomist, specialized in Cynipoidea group. She performed her PhD at the University of Barcelona (Spain). Her PhD was based to solve the taxonomy of an important group of wasps, the Charipinae (Hym., Cynipoidea: Figitidae). Members of the subfamily Charipinae (Hymenoptera: Cynipoidea: Figitidae) are secondary parasitoids of aphids via Aphidiinae (Hymenoptera: Braconidae) and Aphelininae (Hymenoptera: Aphelinidae) and secondary parasitoids of psylids via Encyrtidae (Hymenoptera: Chalcidoidea). The charipines affect effectiveness of the primary parasitoids by decreasing their abundance and modifying their behavior. As a result, increase of aphid host populations can cause severe yield losses in some of the most important crops. Therefore, studies on the subfamily Charipinae have a great economical and biological importance. The knowledge about the subfamily Charipinae has been significantly increased, with special attention to the Alloxysta and Phaenoglyphis, the most abundant and widely distributed genera within this subfamily; these genera are also the most important affecting to the practices of aphid biological control. Thanks to the study of this type material, with the revision of many specimens deposited in different institutions and sent to the University of Barcelona, it has been possible to establish the interspecific limits based on morphological features, making new synonymies or breaking down groups of species when it has been necessary. Now the taxonomy of this group is completely solved, for consulting please visit: http://www.charipinaedatabase.com
Lately, she has been working improving the molecular knowledge of Charipinae subfamily, obtaining the BARCODE of most of the valid species and many advances have been made clarifying the phylogeny of this subfamily. Additionally, works related with the aphid trophic associations have been performed to include the Charipinae knowledge in aphid biological control programs.
