Abstract

For many years entomologists have agreed that the codling moth, Carpocapsa Pomonella L., is not attracted to lights. A test, in 1926, with light in a closed storage room, in which codling moths were emerging, however, showed that they were readily attracted to a small light. A test in an orchard subsequently showed them only slightly attracted to a light trap in a tree top. Another test, in 1927, which was much more comprehensive. showed them readily attracted in large numbers to varying intensities of light in light traps operated under normal orchard conditions.
