Overview

Excerpt from The San Jose Scale in Illinois The surface of the bark, when it is completely covered, has to the naked eye a minutely roughened, incrusted, and unhealthy look, and a dusky or dark grayish hue. If the surface be rubbed by the finger, it will have a greasy feel, due to an oily fluid from the crushed insects. Examined under a good glass, the nipple-like centers of the young scales and the circular grooves surrounding these give a very characteristic appearance to the encrusted sur face. From other common fruit scales it is very readily distin guished, especially in the winter, by its circular form, by its smaller size, and by the absence of eggs beneath it. The other common apple scales are the oyster-shell bark-louse and the scurfy scale, both of which are oblong, varying in length from a tenth to a sixth of an inch. Under each scale of these species will be found at this season a little collection of oval eggs, yellow or nearly white under the oyster-shell scale, and maroon-red under the scurfy scale. The San Jose scale, on the other hand, does not commonly lay eggs, but brings forth its young alive. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
