Abstract
A number of the bait experiments of previous seasons for Laspeyresia molesta were repeated and in most cases the results obtained were duplicated. Enameled stewpans and wide mouth, glass, quart jars proved to be the most satisfactory containers. Some 250 aromatic chemicals tested. Terpineol and several essential oils (fennel, Bergamot, star anise, anise seed and Pinus sylvestris) were somewhat attractive to moths. If one compares attractiveness of anyone of these products with that of several fermenting sugar-possessing it is much less. Fermenting fruits (dried fruit in water), particularly prunes, pears and apricots, attract a goodly of moths. Baits made of cheap black-strap molasses (5 to 20 per cent dilutions) are fairly attractive but they usually produce considerable their period attractiveness is not very long. Honey, corn syrups, refiner's syrups and brown sugar (5 or 10per cent solutions) are much more attractive than black-strap molasses. These products an(1othels of a similar nature produce little or no scum when fermentation occurs and their period of attractiveness is of considerable length (several weeks). Fermentation or some change occurs in all baits made of sugar-possessing commercial products before they become very attractive to the oriental peach moth. Several of the common disinfectants delay but do not permanently prohibit fermentation when added to the sugar-possessing products used in the experiments.
