Abstract
WHILE chemical control is in general the most effective method of pest control known and therefore the most generally used, an increasing amount of experimental proof has accumulated during recent years showing that this method has a very serious limitation. Repeated applications of chemical control result in an unintended artificial selection of those mutants within the pest population which happen to be resistant to the poison used. The progeny of these surviving mutants develop races of the pest which are more difficult to control than the general population.
