Chemical Control

Abstract

Man has to compete with insects for many of his fundamental needs, and for this reason battle lines have been drawn out since prehistoric days. There is evidence that humans have been engaged in war with pests for more than 4000 years (Conway, 1976). Astonishingly, although the conflict is old, its dynamics and the behaviour of its main participants are still not well understood. Even the objectives, at least of man, are poorly defined. Only in recent decades have people begun to ask fundamental questions, and to search for sophisticated methods which would respect both nature, and human needs.
