Summary:Transmission of dengue type 1 was demonstrated for 3 strains of Aedes triseriatus mosquitoes after oral infection. Rates of infection were similar to those observed in a control strain of Aedes aegypti. Three additional species belonging to the subgenus Protomacleaya (Aedes brelandi, Aedes hendersoni, and Aedes zoosophus) were also susceptible to oral infection with dengue type 1 virus but transmission could not be demonstrated although virus was detected in the salivary glands of infected mosquitoes. Virus transmission was demonstrated for Ae. hendersoni following parenteral infection. The results of this study support the view that non-Stegomyia mosquitoes may become involved in the transmission of dengue virus to humans.
