Finally they emerge from the fruits and change to pupae on the outside of the peach, generally in or near the stem cavity. A week later, these pupae change to moths that deposit their eggs upon the peaches, and these eggs hatch into worms that also burrow into the peach fruits, finally maturing and pupating on the putside of the fruits in the same way that the second generation did. ., A week later, the third brood of moths appears, generally during the latter part, of August, and these deposit their eggs upon the bark of the trees. The larvae that hatch from this lot of eggs burrow immediately into the bark and hollow out the hibernating cells. There, is thus in the extraordinary history of this Peach- twig Moth a series of three broods of larvae, one of which is exclusively a borer of bark and twigs, the second of which is both a twig borer and a fruit worm, and the third of which, on fruiting trees, is exclusively a fruit worm. It has been found that the hibernating worms may be de- stroyed by spraying the trees in spring with a lime, salt, and sulphur wash, and the injuries may be prevented to a considerable extent by burying or covering the piles of wormy 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 Weed, Clarence Moores, 1864-1947.
