The Saratoga spittlebug causes “flagging,” severe stunting, and tree mortality in pine plantations. The recommended control, 1 lb DDT/acre, has certain undesirable characteristics. This study was made to test the qualities of malathion with its shorter residual life as an effective substitute. Five replications of each of the following treatments were established in 3 infested red pine plantations: (1) Check, (2) 1 lb DDT/gal/acre, (3) 1 lb malathion/gal/acre, and (4) ½ lb malathion/gal/acre. Adult population estimates were made before and after treatment. The results showed that ½ lb malathion/gal/acre controlled adult Saratoga spittlebugs as well as did 1 lb DDT/gal/acre.
