Zika vector surveys

In 2017, we are surveying selected locations in 5 Wisconsin counties, using the same ovitrap methods as in 2016.  As of June, 2017, we have collected and reared 3 eggs of the Asian tiger mosquito (Aedes albopictus) from a location in Dane County.  Additional surveillance has been implemented to determine the extent of this infestation.  This is the first record for this species in the State of Wisconsin. 

Last summer (2016), the Wisconsin Medical Entomology Lab partnered with the Wisconsin Department of Health Services and local public health offices representing 20 counties in southern Wisconsin in order to look for potential vectors of the Zika virus.

We received over 760 submissions from 21 counties comprising over 22,000 mosquito eggs. Of the samples processed, we had a hatch success rate of 74% and identified two species of mosquito: Aedes japonicus and Ochlerotatus triseriatus; we did not find any Aedes albopictus.
