. Better fruit. Fruit-culture. Page 20 ure almost one-half inch in length. The eggs are white to yellowish, elongate oval in shape. The moths of the last brood deposit eggs late in August and September in crevices and rough places in the bark. When the eggs hatch, usu- ally in about five to seven days, the young larvae dig small cavities in the bark at the base of the new wood, usually at the crotch of the limb where the winter is passed. The hibernating quarters can be found upon close exami- nation (high power lens usually re- quired), as indicated by small reddish brown mounds of chewed bark, and in some cases may be webbed together by bits of web. As spring advances the larvae begins feeding on the surround- ing tissues and reach the surface in from ten to fourteen days. The young larvae immediately attack the buds, de- stroying young fruit and burrowing down the pith' of the tender shoots, causing them to wither and die as the season advances, thus necessitating the uninjured buds below to send out an- nual growth. The same larvae will de- stroy a large number of buds each sea- son, also a number of twigs. When full grown the larvae crawl to the larger branches or the trunk, where they construct very loose cocoons con- sisting of a few threads of silk. Here the pupae period lasts from ten to BETTER FRUIT twelve days. The moths emerge and deposit eggs on the new twigs near the base of the leaves. When the eggs hatch in probably ten days the larvae feed on the tips of the young shoots and at- tack the fruit and eat out a consider- able cavity in the flesh which usually fills with gum. They sometimes eat in the seed and destroy the kernel. The second brood reaches maturity in July and August and pupate in the basin of the stem end of the fruit. The third brood moths deposit their eggs as a rule around the insertion of the stem. This brood of larvae usually feeds entirely on the fruit.
