ling moth larvae, and they have 8 pairs of prolegs on the abdomen, 

 while codling moth larvae have only 5 pairs of prolegs. Addition- 

 ally, the damage caused by sawfly larvae occurs earlier in the 

 spring than codling moth damage. By late June the sawfly larvae 

 are fully grown and leave the fruit to spin their cocoon in the 

 soil where they remain until the following spring when they emerge 

 as adults. 



Control Measures 



The European apple sawfly should be controlled at the petal 

 fall stage as soon as three-fourths of the petals have fallen. It 

 is important to get some of the spray material into the calyx cup 

 before it closes, which means an application as soon as the petals 

 fall. Guthion*, Gardona*, parathion and dieldrin are all effective; 

 however, the effectiveness of Imidan* and Zolone* are not fully 

 known .
