Abstract
Lures containing different amounts of (E)-10-dodecen-1-yl acetate and (E,E)-8, 10-dodecadien-1-yl acetate were formulated in natural rubber stoppers or polyethylene vials and tested in traps in the field to establish relative attractiveness to males of the pea moth,Cydia nigricana (F.), dose-response relationships, and the effects of weathering. Initially, both formulations of (E,E)-8,10-dodecadien-1-yl acetate were much more attractive than those of (E)-10-dodecen-1-yl acetate, but their activity diminished considerably after only 5 days in the field because an inhibitor was formed, and polyethylene formulations were not attractive after one week. However, lures containing (E)-10-dodecen-1-yl acetate, with or without antioxidants, in both rubber and polyethylene were still attractive after three months' exposure in the field and are therefore suitable for practical monitoring of pea moth populations.
