Agricultural development and arthropod-borne diseases: a review

Abstract

A review is presented of the interrelationships between arthropod vectors, the diseases they transmit and agricultural development. Particular attention is given to the effects of deforestation, livestock development and irrigation on the abundance of vectors and changing patterns of diseases such as malaria, trypanosomiasis, leishmaniasis, Chagas' and some arboviral infections. The question as whether keeping livestock diverts biting away from people and reduces diseases such as malaria--that is zooprophylaxis, or whether the presence of cattle actually increases biting populations is discussed.
