Term Noxious fauna

A group of animals considered harmful to human beings. It is an anthropocentric concept that covers those animal species that, under certain environmental conditions, can grow in population and become a plague, potential vectors of infectious contagious diseases, or cause damage to goods and activities of humans. From a biological perspective, noxious fauna does not exist because each species has a function in the ecosystem.

The mosquito that transmits the dengue virus (Aedes egypti) heads the list of noxious fauna in the Dominican Republic. In the last few years there has been a dramatic increase in epidemic dengue, not only in the country, but in the entire Caribbean and in South America, which has been attributed in great part to climatic variations produced by global warming.

Studies conducted in the country have confirmed the influence of climate change in the behavioral variations of dengue. According to estimates, an increase in future dengue cases in the Cibao and Eastern regions of the country is expected, as well as changes in the disease patterns, indicating an expansion of the vector to regions where it currently does not exist.1 These trends are already becoming apparent in the Dominican Republic; for example, the mosquito that transmits the virus has already moved to traditionally colder regions like Constanza and Jarabacoa where it had never been recorded before.
