Insecticides effected important changes in the structure and physiology of the Brassica oleracea L. (Cruciferae) community. The number of species in some insecticide-treated communities were reduced to one-half, relative to the control community. Insecticides severely reduced the numbers of many species populations, but with some insect populations the insecticides caused density increases and in a few cases the populations increased 10-fold. The significant increase in pest populations resulted in most instances from insecticide destruction of natural enemies. Insect control without the usual complications of outbreaks, resistance, and residues is possible if the ecology of populations and communities is thoroughly understood and then insecticides are selectively applied.
