in self defence. Rather, at the outset he should keep the advantage 

 he already has. 



NATURAL HISTORY OF THE CODLING MOTH. 



Contrary to the opinion of many fruit growers, they themselves 

 should be famaliar with the details of the story of the life of the 

 codling moth. Seasons vary in forwardness and with the season 

 \aries the proper time to spray for best results. The fruit grower 

 like the entomologist, to secure the best results, should be so con- 

 versant with the facts of the life-history of this pest that have a 

 bearing on the manner of treatment, that he can safely draw his own 

 conclusions from time to time as the season develops. Thus, he 

 will know when to spray and how often to spray. The following 

 summary of the life history is presented with a view of furnishing 

 a summary of the general information. It is hoped that with these 

 basic facts in the mind of the orchard owner he will make a study 

 of the question as it affects his own mterests. 



THE EGG. 



The freshly laid egg of the codling moth as seen with the naked 

 e3'e appears as a milk white speck somewhat oval in shape one 

 twenty-fifth of an inch across by a very little more in length. Its 

 manner of reflecting the light is characteristic and materially aids 

 in locating it. A profile view shows the egg to be nearly hemispher- 

 ical in its central portion w^ith the oval shaped edge greatly flat- 

 tened out. As the embryo develops the color may become chang- 

 ed to a yellow-reddish tinge due to a ring of reddish color marking 

 the position of the curled caterpillar inside. In a previous report 

 we have called attention to a superficial similarity between the 

 eggs of the codling moth and the bud moth. This discussion oc- 

 curs on page 205 of the ist Annual Report of the State Entomolo- 

 gist. In the Second Report, on page 146, further observations, made 

 by an assistant, Mr. Burle J. Jones, are recorded. The bud moth 

 eggs are laid apparently with less care as to location than are those 

 of the codling moth, those of the former being placed on both up- 

 per and lower surfaces of the leaf, those in the latter position being 

 less abundant..
