Insect resistance to a variety of insecticides has been know since the early years of our present century. It was observed in 1908 and 1914 in Washington D. C. when the San Jose scale, an "insect" resisted the effect of lime-sulphur (Broan, 1957). Broan adequately summarized the widespread resistance of various insects to newer synthetic insecticides in his monograph (1958b) and in his paper on insecticide resistance and Darwinism (1957).
