In this paper we investigate a few examples of potential interest to those concerned with problems regarding the technoscientific scientific exchange between North and South from the social studies of science and technology perspective. We present a review of the state of the art of those subjects we discuss, namely: science, technology and development theories; the Green Revolutions; and technoscience and Cold War in the South. We argue that, in order to understand the role of technoscience, both in the South and the North, it is essential to study the dynamics of the technoscientific exchanges between the Third World and the industrialized countries.
