Repeat the application after the blossoms fall. Prevent the ascent of the wingless females by means of sticky bands or wire-screen traps. This is the pinkish caterpillar which causes a large proportion Codling-moth, of wormy apples. The eggs are laid by a small moth on the (Fig. 147) leaves and skin of the fruit. Most of the caterpillars enter the apple at the blossom end. When the petals fall the calyx is open (Fig. 148), and this is the time to spray. The calyx soon closes and keeps the poison inside ready for the young caterpillar's first meal (Fig. 149). After the calyx has closed, it is too late to spray efifectively. The caterpillars become full grown in July and August, leave the fruit, crawl down on the trunk, and there most of them spin cocoons under the loose bark. In most parts of the country there are two broods annually. Immediately after the blossoms fall spray with I lb. Paris green or 4 lbs. arsenate of lead in 100 gals, of water. Repeat the application 7 to 10 days later. For use with Bordeaux see apple scab. Use burlap bands on trunks, killing all caterpillars. Fi£ 147.
