Excerpt from Bulletins of Alabama Agricultural Experiment Station, Auburn, Vol. 17: Index, Bulletins 144-148 and 22nd Annual Report and Circular No. 3, January to December, 1909, List of Available Bulletins, June, 1910 What IS the scale - The San Jose scale is a minute, inconspicuous insect which does not, to the untrained oh server, appear to be a living creature. The body of the living insect is concealed beneath the circular, waxen scale which it forms for its protection. The largest scalesare smaller than an ordinary pin-head in diameter and are quite ¿at (see Pl. I, figs. 2 and The scales are hardly more than 1-25 inch across and many of them are smaller still. Beneath the scale the body of the insect may be found as a small, immovable, yellow body (if still alive) which if crushed seems to be filled with a rather thin, yellow, oily liquid. The young of this species are born alive and their powers of reproduction are so re markable that a tree bearing but few live scales in the Spring may become quite heavily infested by Fall and will then be liable to severe injury during the following sea son unless some method of destroying the scales is used during the winter. Close observation with the naked eye Shows that the scales are marked with rings of light and dark gray around a nearly black center. When very abundant they give a general ashy - gray appearance to the entire bark which is noticeable at some distance from the tree.
