That will change, however, as Purdue University entomologists lead the effort to modernize the world’s knowledge on arthropod parasites using a three-year, $4.3 million National Science Foundation grant. The Terrestrial Parasite Tracker project will mobilize more than 1.3 million arthropod specimens representing species such as ticks, which spread Lyme disease, and mosquitoes that carry West Nile virus, malaria and other diseases.
