High school science students around Arizona are participating in the second year of an effort to map mosquito activity.
Public health officials say students participating in the so-called "Great Arizona Mosquito Hunt" that kicked off this week set up traps to attract mosquitoes between late August and mid-September.
That time period is the peak season for mosquito activity in Arizona.
The hunt was first conducted in 2015. It helps teach students about mosquito biology and mosquito-borne diseases such as dengue and Zika.
According to health officials, mapping results will indicate where certain types of mosquitoes are found and help agencies to prepare and protect communities against possible introductions of emerging mosquito-borne diseases,
Dozens of schools from almost every county participated in the hunt last year.
