THE CODLING MOTH. 



"The Codling Moth is now one of the permanent in- 

 stitutions of the State, and fruit growing, or at least apple 

 and pear growing, have been rendered very unsatisfactory 

 and uncertain." Sacramento Record- Union. 



To THE FRUIT GROWERS OF CALIFORNIA AND ALL 

 WHOM IT MAY CONCERN : It is unnecessary for our pur- 

 pose to detail the amount of damage done the apple, 

 pear and quince crop of central California since 1874, by 

 the insect pest known as the Codling or Apple Mo*h, as 

 unfortunately it is too well known. 



In June, 1877, we commenced our investigations to 

 obtain reliable information of the natural history and 

 habits of this pest of the orchard, and respectfully submit 

 the result. 



The moth belongs to the famil^Tortrices, the worm 

 the larva of the Carpocapsa Pomonella (the Codling or 

 Apple Moth). The moth passes the Winter in the larva 

 state, and, in some instances, in the chrysalis form. The 

 larva can be found under the loose bark, in the crotches 

 or indents or cracks in the bark of trees affected the 

 previous year. The larva found in apples, pears and 

 quinces are the same species,
