EXPLANATION OF PLATES. 



PLATE L 



Figtire i. — The adult codling moth enlarged (after M. V. Slin- 

 gerland, Cornell Agricultural Experiment Station). 



Figure 2. — The adult codling moth natural size (after M. V. 

 Slingerland, Cornell Agricultural Experiment Station). 



Figure 3. — Side view of full grown larva of the codling moth 

 (photograph by Professor Slingerland halftone used by Simpson in 

 "The Codling Moth," Bulletin Bureau of Entomology, U. S. De- 

 partment of Agriculture. 



PLATE IL 



Figure i. — Cocoons of the codling moth showing pupae (after 

 M. V. Slingerland, Cornell Agricultural Experiment Station). 



Figure 2. — Unbroken cocoon of the codling moth showing the 

 empty pupa case protruding just as the moth left it in emerging. 



PLATE IIL 



The trunk of the tree in this photograph shows a bad scar 

 •caused by the breaking of a limb which affords numerous places 

 for the larvae to hibernate in. The bands are placed on the trunk 

 and limbs to catch them before they reach the scar. In the back- 

 ground the fence, door and rubbish afford the caterpillars excellent 

 places for hiding. 



PLATE IV. 



Orchard owned by Senator W. J. Brennan of Flathead Co. 

 This photograph is to be contrasted with Plate III. The ground 

 is kept so free of weeds and all foreign matter that excellent results 

 in fighting the codling moth might be secured. This insect has not 

 yet reached Mr. Brennen's Orchard.
