During the last 12 years, his scientific work has revolved on the application of several techniques of molecular biology, mainly related to agricultural insect pests and insect vectors of plant diseases belonging principally to Homoptera. In particular, he has focused on the study of taxonomic and phylogenetic of species belonging to suborder Sternorrhyncha. Moreover, he did extended research on phytopathogens within several species belonging to suborders Auchenorrhyncha and Sternorrhyncha and in the development of molecular techniques for the diagnosis of plant disease agents within their insect vectors.
From 2003 to 2008, he has been involved in different studies: distribution and identification of biotypes of whithefly Bemisia tabaci in Sicily; search potential insect vectors of phytoplasmas in vineyards of southern Italy; phylogenic relationship between different aphids belonging to genus Brachycaudus using mitochondrial and nuclear molecular markers; new molecular protocol to distinguish the mealybug species Planococcus ficus and Planococcus citri.
From 2009 to 2010, he carried out a research in the “Dipartimento di Valorizzazione e Protezione delle Risorse Agroforestali (Di.Va.PRA)” at the University of Turin, with the objectives to: identify the species of mealybugs on grapevine in Piedmont and Liguria; deepen knowledge of the transmission of viruses GLRaV-3, GLRaV-1 and GVA by these insect vectors; test the infectivity of natural populations of mealybugs in the vineyard.
From April to December 2011, he has been involved in a study on the role of the Italian populations of Bemisia tabaci and Trialeurodes vaporariorum in transmission of the tomato viruses TICV and ToCV in collaboration with University of Catania and the Plant Pathology Research Centre (CRA-PAV) in Rome.
From July 2012 to February 2014, he carried out a research on the correlation between different biotypesof Aphis gossypii and the CTV virus, agent of the disease known as “tristeza” of citrus at the University of Catania.
From March 2015 to date, at the IPSP-CNR of Bari, he has been involved in the study of meadow spittlebug Philaenus spumarius vector of Xylella fastidiosa in Apulian olive orchards, in particularly: deepen knowledge of the biology, transmission ability of the bacterium and pest control.
