摘要：The authors review the experimental work that has been done since the Second World War on the use of chemical molluscicides in Southern Rhodesia and describe the development of a co-operative snail control campaign involving local landowners and various Government departments. In 1959 and 1960 efforts were concentrated on four large-scale experiments to test the methods of application of copper sulfate, sodium pentachlorophenate and Bayer 73 under a variety of climatic and physiographic conditions. From this work the authors conclude that it would appear possible and practicable to control vector snails in natural water courses and reservoirs in savannah areas of Central Africa to a degree at which it is thought that transmission of bilharziasis from man to man and of fascioliasis from animal to animal does not take place.
