Specimens were sorted by biological condition; those obviously engorged were designated as (E), females with swollen abdomens not conspicuously blooded were considered gravid (G), and those with normal or shrunken abdomens were considered neither blooded nor gravid (U).

A total of 12 mosquitoes were found to be HBAg positive out of 1,658 individuals tested. These were: 9 , 1 (E), 5 (G), 3 (U); 2 , 1 (E), 1 (U); and , 1 (U).
