A total of 11,598 wild-caught female of Culex vomerifer and 229 specimens of other species of Culex (Melanoconion) mosquitoes captured in Almirante, Panama, were allowed to feed on 54 laboratory-bred hamsters. Of the C. vomerifer given access to hamsters, 3987 were observed to engorge on blood. A total of 18 transmissions of arboviruses were demonstrated in hamsters bitten by C. vomerifer mosquitoes, and one strain of Ossa virus was obtained from a hamster fed on by C. taeniopus. Nine of the transmissions by C. vomerifer, 5 of Ossa virus, and 4 of Madrid virus, were identified by isolation of the agents from the tissues of hamsters bitten by these mosquitoes. The other 9 transmissions, five of Guama, and one each of Ossa, Madrid, Patois, and Mayaro viruses, were demonstrated and identified by subjecting the serum of surviving hamsters to HI [hemagglutination inhibition] and CF [complement fixation] tests against antigens of 27 different arboviruses. All 5 viruses transmitted were previously known to occur in the Almirante area, and 4 of them are commonly encountered there. C. vomerifer is a proved vector of Ossa, Madrid, and Guama viruses in Almirante, the first 2 of which are important pathogens to human beings. It is not an efficient vector of VEE [Venezulian equine encephalitis] in the study area even though it is frequently found harboring this viral agent. The species C. taeniopus may be a vector of Ossa and perhaps of other arboviruses when high population peaks are attained.
