Zika vector surveys

The Asian tiger mosquito, Aedes albopictus, was discovered at two sites in Wisconsin in 2017 by the UW-Medical Entomology Laboratory and the Center of Excellence for Vector Borne Disease at UW Madison. This mosquito can transmit Zika, Dengue and Chikungunya viruses.  The risk of transmission in Wisconsin is very low as the tiger mosquito does not survive the cold winters and has to be imported each year.

In 2018, we are surveying selected locations in Wisconsin counties, using the same ovitrap methods as in 2016-17.   This mosquito is a day-time biter and has a very distinctive white stripe on the thorax and head.  If you should capture one, please get in touch so we can follow-up.
