A well-known idiom dictates that “prevention is better than cure”. There are limited vaccines and no therapeutic treatments available for many arthropod-borne diseases. The only proven and consistent method of preventing transmission of the pathogens that cause these diseases is to act on the vectors by suppressing their contact to humans. My research agenda is guided by the above-mentioned idiom and aims at reducing the negative impact of insects on human health by studying aspects of insect biology that could be leveraged to develop innovative strategies of insect control.
Briefly, my main research interests are as follows:
Co-evolution between arthropod vectors and arboviruses.
Emerging or resurging infectious diseases include several caused by arthropod-borne viruses (arboviruses). An example is dengue, with 100 million people infected annually. Despite having different replication strategies, all arboviruses are maintained in a natural cycle involving transmission by the bite of an infected hematophagous arthropod (vector) to a vertebrate host. Once infected with an arbovirus, the vector becomes persistently infected for life. Mosquito competence for arboviruses is a complex and evolving phenotype because it depends on the interaction of genetic factors from both mutation-prone RNA viruses and mosquito vectors with environmental variables. Understanding the genetic components of vector competence and how these genetic elements are distributed in natural populations and interact with environmental factors is essential for predicting the risk of arboviral diseases and for developing new transmission-blocking strategies. I use the tools from a number of scientific disciplines to probe the complicated biology of vector-mediated pathogen transmission, with a current focus on mosquito genomics and immunity pathways.

Insecticide resistance in vectors.
Insecticide resistance is recognized as one of the main obstacles in the malaria elimination/eradication agenda. Understanding the molecular mechanisms of insecticide resistance will provide the tools to derive markers to predict resistance and possibly identify targets for novel insecticide formulations. I applied transcriptomics and molecular ecology approaches to study insecticide resistance mechanisms and the emergence of resistance in malaria and arboviral vectors.

Project Title:
Mosquito microbiota and virome: a focus on Italy
Arboviral diseases are caused by viruses, like Dengue, Chikungunya and Zika, which are spread to people by the bite of infected arthropods, primarily Aedes spp. mosquitoes. Traditionally considered only a minor contributor to global mortality, arboviral diseases have seen an unprecedented resurgence in the past five decades. At the moment, there are no specific arboviral drugs, and licensed vaccines are either available for a limited number of arboviruses, for instance there is not a vaccine for Chikungunya and Zika viruses and only one commercial vaccine is available for Dengue, but it may be accessible for few people at risk of infection, mainly due to its cost. Given this situation, prevention of transmission is critical and the only effective method currently available to reduce the risk of transmission is to act on mosquitoes. Besides being carriers of arboviruses, mosquitoes can be infected with insect-specific viruses (ISVs). ISVs are phylogenetically-related to arboviruses but are not able to replicate in vertebrate cells and infect humans and other vertebrates. Vertical transmission has been demonstrated for ISVs and it is likely the major mechanism ensuring their persistence in nature. Cell-fusing Agent (CSA) was the first ISV isolated from mosquitoes in 1975. More than two decades passed before a second ISV, Kamiti River Virus, was described. This temporal gap was caused by the absence of appropriate tools for a global virome analyses, but also the lack of interest in the scientific community for the study of ISVs, probably due to their not-pathogenic nature in vertebrates. However, this absence of pathogenicity, is what makes them perfect candidates for the control of infection and replication of pathogenic arbovirus in the mosquito vector. Several ISVs, including the Palm Creek virus and Eilat virus, have already been tested for their capacity to interfere with arbovirus growth with promising results.
There are no studies yet on the widespread of ISVs or the use of ISVs for the control of arboviral infections in Ae. albopictus. As a first step to the potential application of ISVs as biological agents for the control of arboviruses in Italian mosquitoes, this project aims to characterise the virome of Italian mosquitoes.

Project Title:
The impact of temperature on Aedes albopictus immunity.
Establishment of the arboviral vector Aedes albopictus in temperate regions of the world fostered the re-emergence or the new introduction of arboviruses. For instance, Chikungunya outbreaks occurred in Italy in 2007 and 2017; France and Croatia suffered from autochthonous cases of Dengue and Chikungunya in several occasions since 2010.
Europe is characterized by a temperate climate with a clear seasonality that translates into a seasonal emergence and activity of mosquitoes. When mosquito emerge in late spring (May-June), temperature averages between 16-18ºC in Italy, while in summer temperature averages 24-25 ºC, with picks above 30ºC. Temperatures at the time of mosquito emergence and during the pick of summer have already been proven to be thermal stressor linked to modulation in immunity gene expression and susceptibility to viral infection. However, there is not a clear understanding of the molecular mechanisms underpinning this adaptation process. This project will combine transcriptional and physiological analyses to understand the impact of temperature on mosquito immunity.
