Abstract
This paper reports the results of a study of the position of the rostralis of various stages of the California red scale, Aonodiella aurantii, when feeding in the tissue of lemon fruit. The average length of the rostralis increased appreciably with each stage of the insect and the scales of each stage fed at different levels in the rind. The path of the rostralis through the rind was irregular. The tip of the rostralis was always located within a cell of the host tissue. There was marked injury to the cells in which 2d- and 3d-stage scales were feeding.
