Blacklegged Tick and Yellowfever Mosquito (IMAGE) Entomological Society of America Caption Between 2004 and 2016, reported human disease cases in the U.S. resulting from bites from arthropods -- primarily ticks and mosquitoes -- tripled, according to the US Centers for Disease Control and Prevention (CDC). Under the stewardship of the Entomological Society of America, 18 scientific and medical societies, professional associations, and advocacy groups have formed the Vector-Borne Disease Network, a new coalition that will stand ready to advise and support federal policymakers in confronting the challenge of diseases spread by insects and related arthropods.
