Each little apple is held up with its ealvX lobes spread; the poison settles in the cavity at the blossom end, and here nefst of the young larva.; take their first meal. As the calyx 11Wes close soon after the blossoms fall, the poison is kept waiting for the larva. A week or ten (lays later a second spraying is usually given to catch belated larv{e. lint the first is the critical and all-important spraying. It is estimated that it will save at least seventy-five per cent of the apples that would he wormy if the tree were not sprayed.
The _MO-moth lives over winter as a half-grown larva in a small silken case fastened to a twig. It comes forth in spring to feed upon the tender green of swelling buds. The mutilated leaves, drawn together by threads, form a shelter for the larva, and in this retreat the cocoon is spun. Emerging in June or July the moth lays its eggs, which hatch in it short time, and the by feeding on the leaves, attain a considerable size before they go into hibernation. A thorough spraying with Paris green as the buds are swelling, and a second one just before the blossoms open, are fairly effectual in ridding trees of the bud-moth.
Canker-worms are the smooth-bodied measuring-worms that infest apple and other fruit trees. They are striped with yellow and brown, and when mature are about an inch 'They feed upon the leaves in spring, and when full grown let themselves down by threads and pupate in the ground. When the adults emerge, the wingless females trawl up the trunks and lay their eggs on the branches. The old method of cont bating this insect was to wrap the trunk with cotton or tarred paper to prevent the females from ascending to lay their eggs. The simpler way is to drench the tree with Paris green mixture just after the blos soms fall, so as to catch the young caterpillars just as they begin to attack the leaves.
