Mosquitoes such as Aedes aegypti carry and transmit viral pathogens such as dengue, West Nile, and Zika. A team of researchers in Australia has developed modifications to common mosquito traps that will allow the collection of mosquito excreta, or liquid waste, from which signs of viral infection can be detected—a method the researchers say promises to be faster and more efficient than other existing methods for detecting disease pathogens in wild mosquito populations.
