Examples
-
These flies carry a microscopic organism called a trypanosome which is communicated to cattle causing a deadly disease called "nagana"; certain species of the fly carry a special variety of trypanosome which produces "sleeping sickness" in man.
-
Currently, the mainstay of the control of tsetse flies, vectors of trypanosomiasis (causing sleeping sickness in humans and nagana in cattle) is the use of traps (slide J. 7).
