Part II. holoendemic malaria—the entomological picture

The main vector of the Maprik area is A. punctulatus which maintains a high population density throughout most of the year. The natural daily survival rates of this and the related A. farauti and A. koliensis are higher than formerly estimated, and this in turn permits the development of high sporozoite rates. All members of the A. punctulatus group spend at least part of the night indoors, and the actual length of time may depend on their respective peak biting times. In Part III of this series the data accumulated so far will be analysed and interpreted in relation to the possibilities of malaria control. References will be given at the conclusion of Part III.
