Surprising though it seems, the world faces almost as great a
threat today from arthropod-borne diseases as it did in the heady
days of the 1950s when global eradication of such diseases by
eliminating their vectors with synthetic insecticides, particularly
DDT, seemed a real possibility. Malaria, for example, still causes
tremendous morbidity and mortality throughout the world, especially
in Africa. Knowledge of the biology of insect and arachnid disease
vectors is arguably more important now than it has ever been.
Biological research directed at the development of better methods
of control becomes even more important in the light of the partial
failure of many control schemes that are based on insecticide-
although not all is gloom, since basic biological studies have
contributed enormously to the outstanding success of international
control programmes such as the vast Onchocerciasis Control
Programme in West Africa. It is a sine qua non for proper
understanding of the epidemiology and successful vector control of
any human disease transmitted by an arthropod that all concerned
with the problem - medical entomologist, parasitologist, field
technician - have a good basic understanding of the arthropod's
biology. Knowledge will be needed not only of its direct
relationship to any parasite or pathogen that it transmits but also
of its structure, its life history and its behaviour - in short,
its natural history. Above all, it will be necessary to be sure
that it is correctly identified.
