Abstract
SEVERAL recent papers have compared the effectiveness of bait and light traps as means of estimating changes in adult codling moth populations and of timing the application of sprays1–3. The comparison of these trapping devices was based, in each instance, on the total number of moths caught over periods considered to have been critical for the subsequent infestation of the crop. In these investigations no attention was paid to the quality of the respective catches beyond noting the difference in the relative frequency of females attracted to each type of trap.
