Abstract
There is little doubt that the insecticides parathion, malathion, and TEPP prevented a widespread devastation of California's alfalfa industry following the 1954 appearance of the spotted alfalfa aphid—Therioaphis maculata (Buckton) but the materials also proved to be toxic to insect enemies of the aphid.
