The Codling Moth is probably the most notorious of all 

 apple pests and is to be found in almost every country in 

 which apples are grown. The damage is caused by the larva 

 which burrows into the fruit and so produces the worm-eaten 

 or maggoty apple which must be familiar to everybody. 



It must be noted, however, that there is a further pest, the 

 Apple Sawfly (Hoploc&mpa testudinea), the larvae of which 

 damage the apples in much the same way as those of the 

 Codling Moth, and it is very necessary to distinguish between 

 the two, since the methods of control in the case of the Codling 

 Moth are quite useless when employed against the Sawfly. 

 An account of the Sawfly will be found in Leaflet No. 205. 

 but the chief distinguishing features are also given below in 

 the sections " Description and Life History of Insect " and 

 ' ' Nature of Damage. ' ' 



Description and Life History of Insect.. The Codling 

 Moth measures from ^-f inch in spread of wings and ^ inch 

 from head to tail (tip of abdomen). The fore-wings are dark 

 grey with numerous waved brown lines giving the appearance 

 of watered silk. Near the end (outer margin) of the wings 

 is a brown patch which in certain lights has a coppery 

 metallic lustre, the most characteristic feature of the moth. 

 The hind wings are greyish brown often with a coppery tinge.
