It was found at Letaba that red scale (Aonidiella aurantii Mask.) was kept under adequate commercial control by its natural enemies in certain plots which adjoined some of the most heavily scale-infested plots. These ""natural control"" plots had not been treated with red scale insecticides for a number of years, and they only differed from the scaly plots with their pure or almost pure populations of either Pheidole megacephala F. or Anoplolepis custodiens Smith, in having mixed populations of several species of ants.
