Abstract
Oriental peach moths are attracted to fermenting molasses baits from the middle of April until the middle of October. Some or many males and females may be found in the bait containers every day during the entire season. This year, 1925, at Riverton, New Jersey, the largest number of adults were captured during the emergence period of the first brood moths. Later broods were reduced by parasitism. The graphs show that more moths came to the same sort of bait located in peach orchards than in apple or quince orchards. An enameled stewpan has proved to be the most satisfactory container for baits. So far as known bait containers should be well filled in order to catch the maximum number of adults. Containers placed high in the tree catch more moths than those placed low. Cheap stock-feeding molasses seems to be the most satisfactory grade of molasses for baits. Dilutions of 1–10 and 1–20 are more satisfactory than weaker or greater strengths. Yeast is unnecessary. Under most conditions natural fermentation makes a better bait than where yeast is added. Corn syrup, particularly the colorless grade, diluted 1–20 with water, attracted large numbers of moths.
