The results of a nine-weeks survey in selected localities of the Republic of Nicaragua are presented as a contribution to a fund of information upon which might be based the formulation of programs for the control and eradication of arthropod-born diseases. A list is given of 124 species which are distributed among the Culicidae (38), Muscoidea (15), Tabanidae (14), Mallophaga and Anoplura (8), Acarina (5), and several other groups (44), with geographical distribution records and life history notes. The probable vectors and the transmission of prevaliling arthropod-borne diseases are discussed. Malaria, the dysenteries, typhoid, myiasis due to Dermatobia hominis, and perhaps filariasis, are common. Suitable vectors are numerous, widely distributed, and uncontrolled.
