Analysis of Asian longhorned ticks collected in Pennsylvania found just one—out of more than 250 tested—carrying the bacteria that causes Lyme disease. The invasive tick is unlikely to play a role in Lyme transmission, but the research underscores the importance of active tick and pathogen surveillance and collaboration among agencies at local, state, and national levels.
It's not enough to know mosquito abundance in a given area. Rather, the rate at which mosquitoes and humans actually come into contact is critical, a group of researchers say, to better understanding and modeling mosquito-borne disease transmission.
Researchers in Florida have pinpointed the local overwintering habitats of mosquitoes that host eastern equine encephalitis virus. They hope targeted control efforts can cull those mosquitoes before they transmit the virus to birds that carry it north to other parts of the country.
Biosecurity research at Kansas State University adds to the chorus of studies showing mosquitoes and other insects are not biological vectors of SARS-CoV-2, the coronavirus that causes COVID-19. Here's a look at how that research is conducted.
