Tests of various syrup baits and aromatic esters with respect to their attractiveness to Codling moth (Carpocapsa pomonella) are reported for the period of 1928-31, inclusive. As previously reported, Brer Rabbit syrup diluted with water at the rate of 1 to 10 proved to be the most attractive of all baits tested in New Mexico. The addition of 2 per cent sodium benzoate increases its attractiveness through retarding and lengthening fermentation. This is not as noticeable during the spring months as in summer when temperatures are higher. Malt syrup when used without yeast is moderately attractive. Of thirty-five esters tested, Ethyl oxyhydrate, Iso butyl phenyl acetate and Diphenyl oxide were the most attractive. They did not, however, exceed Brer Rabbit syrup bait in attractiveness, nor did they add materially to the attractiveness of this bait when placed in it, directly or in Peterson Evaporation cups. Commercially prepared extracts of the aroma of apple blossoms and apple fruit, or apple fruit flavors, were not attractive to the Codling moth. Esters of malic acid were only slightly attractive and esters of valerianic acid were not at all so.
