Summary Not Available – First paragraph follows:
Precise measurement of insecticide toxicity against house flies from various poultry ranches, dairies and cattle feed lots provided evidence of the presence of resistance roughly in proportion to the extent of insecticide use in each situation. The data indicate where changes to new insecticides are advisable, and illustrate how heavy reliance on insecticides over several years for fly control leads to gradual depletion of available insecticide resources.
