The mosquito is a highly effective and deadly vector for human disease agents. The tiny insect has played a powerful role in spreading viruses such as West Nile, St. Louis encephalitis, western equine encephalitis, dengue, and Zika.
In the Coachella Valley, we regularly detect 13 mosquito species. The species of greatest public health concern in the valley are the Culex tarsalis, Culex quinquefasciatus and the Aedes aegypti. These species are capable of transmitting micro organisms that cause disease in people.
