never seen over five per cent of the apples from an unsprayed 

 orchard infested with codhng moth, while in the sprayed or- 

 chards we often get only one wormy apple in five thousand; 

 at the same time, in Queens county, where there are some large 

 orchards and practically none of them sprayed, the codling 

 moth will often infest 30, 40 or even 50 per cent of the crop. 

 1 his shows us conclusively that when we spray we control a 

 lot of codling moth for our neighbors who do not spray, and 

 conversely, they breed a lot of codling moth to fly into our 

 orchards and reduce the efficiency of our sprays. 



Bud-moth. 



This insect, Mr. Yeaton tells me, has done you more damage 

 (hiring the past season than all of your other insects combined 

 and therefore merits very serious consideration. 



The life history is as follows : The adult, a very small, ashy 

 gray moth, flies during July and deposits its small silvery scale- 

 like eggs, singly, on the under surface of the leaf. In about 

 two weeks the young larvae emerge and crawl to the midrib 

 on the nearest large vein and there eat their way into the tissue 

 of the leaf, feeding up to the top row of cells, leaving only a 

 tissue on the upper side of the leaf ; while on the under side it 

 spins a silken web, incorporating into this the downy hairs of 

 the under surface. If two leaves touch each other the young 

 larvae will tie the two together and feed off the surface of each 

 or, if the leaf touches an apple, the bud-moth will tie the leaf 

 to the apple and feed off the surface of both the leaf and 

 the apple, eating through the skin and spoiling the keeping 

 qualities even more than black spot. As a rule, from one to 

 three apples are injured in this way in the fall for every ten 

 per cent of the buds infested with bud-moth the previous 

 spring. 



About the time the first killing frosts occur, the young bud- 

 moth larvae, for the most part now in the third stage, crawl 

 back the petiole and select crevices in the fruit spurs, often 

 under old budscales, and there form cocoons in which to pass 

 the winter. When the buds swell in the spring the young bud- 

 moth larvae emerge from their winter cocoons and bore into the 

 tips of the open buds. As the bud opens and the leaves unfold
