Entomological activities during the yellow fever epidemic in Trinidad 1978-1980



Entomological activities during the yellow fever epidemic in Trinidad 1978-1980



Bulletin of the Society for Vector Ecology, 151: 41-47



An epidemic of sylvan yellow fever occurred in Trinidad during the period 1978 to 1980. Entomological activities were initiated at various localities where monkey (Alouatta spp.) mortalities were reported. A total of 5,468 Haemagogus janthinomys was colleced and tested which resulted in the isolation of 17 strains of yellow fever virus. Two strains of the virus were isolated from a total of 49 Haemagogus leucocelaenus and these constituted the first isolations of yellow fever virus from this species of mosquito from Trinidad. Attempts to demonstrate transovarial transmission of yellow fever virus from adults reared from eggs and larvae collected in the field were unsuccessful. However, from two locations virus isolations were made at the end of the rainy season (January) and at the beginning of the successful rainy season (June).
