A thick wash of soft soap applied to the stems in June will deter the beetles from laying their eggs upon them. There are other borers that injure other trees. It is in search of these that the woodpeckers work so systematically around the stems The woodpeckers are among the fruit-grower's allies, and should not be molested. The borer of the currant stems is the larv^a of a pretty little clear-win £ moth, JSgeria tipuli/ormis Linnaeus (Fig. 17). Late in the fall all un- healthy-looking stems in the red, white and black currant-bushes should be cut out and burned. The moths appear in June, and consort for safety with the small black wasps of the genera Odynerus and Gorytes, which they somewhat resemble. A child can soon learn to distinguish them from these, and can spend a few bright midday hours profitably in capturing the moths with a butterfly net. The capture of one female will save many currant stems from damage. We have, then, glanced at some of the worst of the insect pests that frequent the farmer's garden. The study of them in their native haunts will be found full of interest and a knowledge of their proceedings and the various methods of counteracting them' will prove of great value, and ought not by any to be lightly Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Entomological Society of Ontario; Ontario.
