The damage to the interior of the fruits is very dilTei-ent from 

 that of the Codling IMoth. The sawfly larva? eat out large cavities 

 in the centre of the ajiple, and tliere is always a circular opening to 

 the exterior even when the larv;r are quite small. The damage in 

 the young fruit checks the growth and il soon falls, the larva' 

 entering fresh fruitlets ; when more mature fruit is attacked the 

 whole of the interior is eaten out (Fig. '.I8) and a large black wet 

 cavity is formed. ( )ne oi- more lar\'a' may be found in the same
