| dc.description.abstract | Best results were obtained with syrup baits when diluted 1 part syrup to 20 parts of water. Tin traps were most satisfactory when painted inside and out with aluminum paint. A syrup bait was effective for an average of 5 weeks without change when water was added after the first two weeks. The cost of baiting does not prohibit the use of bait traps, but it should not exceed $5.00 per acre. Terpinyl acetate to which 2 percent of sour milk had been added was the most effective bait for the oriental fruit moth. Goulac 1 part, brown sugar 1 part, and water 40 parts was a very effective codling moth bait. Quart oil cans when not painted lasted only one season. Less than 50 percent of the eggs had been deposited when the female moths were captured. Data obtained support the conclusion that the moth population can be greatly reduced in an orchard by the use of bait traps. The value of bait traps in reducing the percentage of wormy peaches was obscured by the very light infestation of the fruit both in orchards where traps were used and in orchards where they were not used. Biological control of the oriental fruit moth was important in 1934. | en |
