Liberata Gualtieri

My research involves the study of population genetic of some invasive exotic insects and the complex of indigenous parasitoids that have quickly adapted to them, in order to improve knowledge of the mechanisms that regulate their adaptations, for development of protection protocols eco-sustainable. This activity is organized on different lines of research: the study of fillominatore Coptodisca lucifluella (Clemens) and its indigenous parasitoid eulophidae Cirrospilus coptodiscae; morpho-bio-molecular parasitoids of Dryocosmus kuriphilus; molecular characterization of parasitoid Dinocampus coccinellae; molecular characterization of some parasitoids of invasive cerambycidae Anoplophora glabripennis. I am also doing the molecular characterization of the eulophidae Thripobius javae.
Another field of research is the study of eulophidae with parthenogenetic reproduction (Leptocybe invasa, Quadrastichus mendeli, Neochrysocharis formosa) focusing on the symbiont manipulators of host reproduction (Rickettsia spp. ) and on their possible horizontal host–parasitoid transmission.
The characterization of insects and their symbionts was carried out by genomic analysis (DNA extraction, DNA-PCR amplification, DNA electrophoresis on agarose gel), editing the genetic sequences for consecutive phylogenetic analysis.
Another activity is the study of the biology of Baryscapus silvestrii raising on the substitute host Ceratitis capitata, for its possible use in biological control plans, and of Rhagoletis completa, in order to connect its presence with the damage on drupes.
