ResumoTwenty-two Phlebotomus fever group arboviruses were inoculated intrathoracically into male and female Aedes albopictus and Culex fatigans . Eight of the viruses (Itaporanga, Arumowot, Bujaru, Karimabad, Salehabad, Pacui, Chilibre and BeAn 100049) multiplied in 1 or both mosquito species maintained at 32°C for 10 days. Icoaraci virus was detected in mosquitoes after the 10-day incubation period but did not increase in titer. The remaining 13 agents tested did not survive following inoculation. Results of these experiments indicate that the mosquito inoculation technique is less effective for propagation of Phlebotomus fever group viruses than culture in Vero cells or newborn mice. Attempts to demonstrate vertical transmission of Itaporanga and Arumowot viruses by infected A. albopictus and C. fatigans were unsuccessful.
