Role of pesticides in the integrated control of disease vectors.

An enormous challenge for the entomologists and public health specialists of the next 30 years, is the development of integrated control programs to complete the conquest of the important vector-borne diseases of man: African and American trypanosomiases, filariasis, onchocerciasis, scrub typhus, trachoma, and encephalitides. New insecticides will play an important role in these programs. However, we must learn to use these chemicals in ways which will maximize effectiveness to vectors, minimize side-effects to man and the environment, and permit their use at costs which can be met by developing countries. This will require an immense amount of research directed at full understanding of the ecology of the vector species and their interrelationships with man and animal reservoirs of the disease.
