From page 11... ...
Some individuals in a pest population may be able to survive initial applications of a chemical designed to kill them, and this survival may be due to genetic differences rather than to escape from full exposure. The breeding population that survives initial applications of pesticide is made up of an ever-increasing proportion of individuals that are able to resist the compound and to pass this characteristic on to their offspring.

From page 12... ...
When pest organisms are resistant to one class of pesticide compounds, they may evolve resistance more rapidly to new groups of chemicals having either similar modes of action or similar metabolic pathways for detoxication. There is particular concern that the pyrethroids may have a short useful life against many pest species because of a gene identified as kdr.

While it is unrealistic to expect biotechnology to eliminate the problem of pesticide resistance, emerging science does indeed offer great hope in helping reduce the impact of resistance episodes while keeping down the economic and environmental costs of pest control. For a more detailed discussion of an optimistic view of the future and data showing falling pesticide prices to farmers, see Miranowski and Carlson (this volume)
