Species and varieties of malaria vectors in Africa and their bionomics.

Abstract: This summary is based on my book dealing with the Ethiopian Anophelini and work published subsequently. More recent information has been supplied by Mr. D. J. Lewis Sudan; Professor Millot Madagascar; the Director of Medical Services Uganda; the Director of Medical Services Mauritius; the Director of Medical Services Northern Rhodesia; Dr. Bagster Wilson; and Dr. I. Vincke. I am grateful to these gentlemen for replying to my request for information. I propose to deal only with those species which have been found infected in nature and must leave out those which have been incriminated on epidemiological and experimental grounds only. Species in which naturally occurring infections have proved to be of non-human origin are not included (e.g. Anopheles dureni). As forecast in 1947 there has been an increase in the number of anophelines found infected in nature. Many of these additions are exophilic species which bite man in the open near their breeding-places. Vincke is of the opinion that these exophiles are not important as vectors because of their short life-span as determined by him in Katanga (Belgian Congo). If climatic conditions should be favourable for an increase in longevity then these exophiles may become important. It remains of course to be proved that the infections in many of these exophilic anophelines are due to human plasmodia. An interesting example in this connexion is dureni which was formerly thought to be an exophilic vector of human malaria but in which the infections have now been proved to belong to a non-human species (Plasmodium berghei).
