Anthropogenic impacts on mosquito populations in North America over the past century

By Ilia Rochlin, et al.

Exploding mosquito populations in North America are due in large part to urbanization and the ban on the use of DDT.

While many have argued the recent emergence and spread of tropical viruses including Zika, Chikungunya, and Dengue fever is due to human caused climate change making new areas habitable to their host, mosquito’s, in fact, this study shows urbanization and the ban on the use of DDT were the strongest drivers of changes in mosquito populations over the last eight decades in areas on both coasts of North America. The explosion of mosquito populations and mosquito borne viruses do not correlate to temperature changes.
