Abstract

Electroantennogram responses to isomers of dodecenyl, tetradecenyl, and hexadecenyl acetates and alcohols followed by field screening tests indicated that (E)-9-tetradecenyl acetate (E9-14:Ac) is attractive to male Zeiraphera Canadensis Mutuura and Freeman. Traps baited with dosages of either 1 or 10 μg of E9-14:Ac on rubber septa were the most attractive. Traps hung in white spruce trees caught significantly more males than those hung on poles between trees. Vertical location of traps within the tree crown was important; mean catches were greatest in the upper third of the crown. No consistent differences in the numbers of males caught were obtained in a comparison of two nonsaturating traps (Multi-Pher and Uni-trap), and one sticky trap (Pherocon ICP).
