[When Urban and Agricultural Activities Favor the Proliferation of Mosquito Nuisance and Vectors of Pathogens to Humans].

Big cities have thrived on all continents, so have domestic and industrial wastes not to mention the often irrational use of agricultural inputs (fertilizers and pesticides) detrimental to plants and animals. One hundred and eighty million tons of fertilizers and 2.4 million tons of pesticides are spread every year worldwide. Such pollutions, whether urban or rural, have a significant impact on the biology of mosquitoes. Today some urban spaces have properly become a land of plenty for mosquitoes. The combined use of fertilizer and pesticides in the country, quite paradoxically also favor their proliferation. Ironically the very reasons that account for the multitudes of mosquitoes are the exact reasons responsible for the depletion of biodiversity.
