The species of organisms that enter new habitats that are unusual for them, causing an economic, environmental and / or dangerous impact on human or animal health are called "invasive".
In Italy since the late 1990s there has been a progressive increase in the spread of invasive mosquitoes
starting with the infamous tiger mosquito, Aedes albopictus, which rapidly expanded its distribution to become the most widespread mosquito in Europe at least in the urban context.
Subsequently other Aedes species were introduced in Europe including, more recently introduced in Italy, Aedes koreicus and Aedes japonicus.
Environmental and climatic changes are leading to an increase in imported exotic mosquito species as evidenced by the recent entry of these two new invasive species whose potential to transmit pathogens is still largely to be defined.
The success of these mosquito species in terms of reproduction and dissemination is given by the ability of these to adapt to the temperate climate and the ability to survive the winter in quiescence.
Aedes koreicus is a species of Asian origin naturally present in South Korea, Japan, China and eastern Russia. This species was first detected in 2011 in Italy in the province of Belluno from where it spread to Lombardia and Liguria. Although many ecological aspects of this species are still to be explored, we know that it performs the winter diapause, adapts well to the peridomestic environment, bites humans during the day and shows greater tolerance to low temperatures than the tiger mosquito. The ability to transmit pathogens in this species is still under study; however, it appears to be a vector of the Japanese encephalitis virus and the nematode Dirofilaria immitis; it has recently been recognized as an ineffective vector of the Chikungunya virus while studies are currently underway for the competence towards the dengue virus.
Aedes japonicus is a species native to Japan, southern China, Korea, Taiwan, and southern Russia. It is one of the most invasive mosquito species in the world and has spread throughout North America and Europe in recent years. In Italy for now it is present in Veneto and Friuli Venezia Giulia. The species, when present in high densities, is a good vector of the West Nile virus. This mosquito is a species that can tolerate low temperatures; in fact, the expansion towards the south in our country seems to be limited by the higher average temperature which instead favors high densities of Ae. albopictus with which it competes for the use of larval habitats in the plains. In areas where it is present in Italy, the adult is already active in early spring and remains so until autumn, anticipating the appearance of the tiger mosquito and disappearing shortly after this.
To solve the age-old problem of the presence of mosquitoes, it is essential to rely on a company specialized in the field of pest control that carries out targeted interventions and applies the various control strategies aimed at containing the infestations.
Gallura Disinfestazioni is specialized in the execution of pest control interventions in public areas, schools, hospitals, institutions, libraries and parks, but also in private civil or industrial areas, villas, apartments, hotels, campsites, condominiums, gyms, swimming pools, bars. , restaurants, supermarkets, industrial warehouses and means of transport such as ships and airplanes.
We operate throughout Northern Sardinia and specifically in the areas of Olbia, Porto Rotondo, Porto Cervo, Palau, Cannigione, Santa Teresa di Gallura, Arzachena, Golfo Aranci, Loiri Porto San Paolo, San Teodoro, Budoni, Siniscola and Nuoro.
