title: Survival of arboviruses in trypanosome-infected triatomines.
abstract: The potential of triatomines to maintain arboviruses was demonstrated by the ability of Rhodinius prolixus with experimentally punctured abdomen to harbor Venezuelan equine encephalitis (VEE) virus for at least 4 months and St. Louis encephalitis virus for 1 month. At 30 days after infection VEE virus was found at low titers in Trypanosoma cruzi-infected R. prolixus and at moderate titers in T. rangeli-infected R. neglectus. Transmission of VEE virus by bite of punctured bugs was successful 2 weeks after virus ingestion; attempts at 30 days failed.
