Home Nature-Study Course'. this door some tiirie before it is ready to leave the apple and plugs it with a mas^ of debris fastened together with the silk. As it leaves the apple the remnants of this plug may be seen streaming out of the opening. Often also there is a mass of waste pellets pushed out by the young larva from its burrow as it enters the apple. Thus it injures the looks of the apple from the outside at both entrance and exit. If the apple has not received infection by lying next to another rotting apple it almost always first begins to rot around the burrow of the worm, especially near the place of exit. The larva injures the fruit in the following ways: the apples are likely to be stunted and fall early; the apples rot about the injured places and thus cannot be stored successfully; the apples thus injured look unattractive and, therefore, their market value is lessened; wormy apples packed in barrels with others will rot and contaminate all the neighboring apples. The codling moth also attacks pears and sometimes peaches. It has been carefully estimated that every year the codling moth does three million dollars worth of injury to the apple and pear crops in New York State. Think of paying three million dollars a year for the sake of having wormy apples! The larvae usually leave the apples before winter. If the apples have fallen they crawl up to the tree and there make their cocoons beneath the loose bark; but if they leave the apples while they are on the trees they spin a thread and swing down. If carried into the storeroom or placed in barrels they seek quarters in protected crevices. In fact, while the)?- particularly like the loose bark of the apple trees, they are likely to build their cocoons on nea
