Abstract

, and sp. trapped alive in Pleiku, Vietnam, were combed for fleas during 1966–68. Only were collected from all mammals, and 94% of the fleas were on . Montly flea indices showed an inverse correlation with rainfall in Pleiku. Published data on flea indices and reported cases of plague indicated that these were inversely proportional to rainfall in Pleiku, Nha-Trang, and Saigon/Cholon. When the index is 1, 73% of the rats have no fleas. This may be the reason for outbreaks of plague of limited scope, duration, and intensity in the Central Highlands, where flea indices are suppressed by considerable rainfall. During the dry season. the index increases threefold monthly.
