Tests with Bait and Light to Trap Codling Moth

Abstract
A cheaper trap of effectiveness equal to the electrocuting type was sought from 1934 to 1936, through a duplicate, rotating setup of 6 trap types in an unsprayed apple orchard. Molasses-water bait, 1-10, in 12-inch diam. pans, trapped 6 times as many $ moths when lighted with a 75-watt bulb as when unlighted, and more than twice as many as the electrocuting traps. Patented insect-trapping glass globes, when darkened so that light was emitted only through the trapping slots, caught 9/10 as many 2 moths as the electrocuting traps, without the use of an attra-hent. Anethol, added to bait traps, increased the catch of 2 moths more than 5 times.
