Abstract
The apple sawfly (Hoplocampa testudinea (Klug)) is a pest of apple in many parts of Britain. Injury is caused by the caterpillars burrowing in the fruit and is sometimes mistaken for that caused by caterpillars of the codling moth (see page 109). All the fruit infested with sawfly falls during June and early July, and some of the remaining fruit is reduced in value by scars caused by young caterpillars that failed to establish themselves (Figs 17.1 and 17.2). Because of its thinning action sawfly attack is less important in years when fruit set is heavy.
