The Species Control of Anophe Lines in India

dominated life in the tropics. That hope has proved unfounded because the control of mosquitoes in general, and anophelines in particular, appeared to many to be too vast a task, and practically no use has been made of the fact that, in any one area, there is rarely more than one species of anopheline requiring control. It is only in recent years that this fact has been appreciated and made use of on a large scale in malaria control in India. The habits of one Indian species have now, however, been studied in great detail and the knowledge thus gained utilized in its control. Efficient control on biological lines has been instituted on a large proportion of the tea plantations of northern India, which had previously suffered particular loss as the result of the importation of large numbers of labourers who are not immune to malaria.
