Abstract
E∶Z blends of (E)-11-tetradecenal were field tested (three experiments) for their attractiveness to male spruce budworm,Choristoneura fumiferana (Clemens), moths in northern Maine. Blends of 92.5–99%E isomer caught the most moths (three experiments); blend 95%E had the highest cumulative catch throughout two experiments. Rates of catch per hour for the four most attractive blends (92.5–99%E) showed highly variable responses among experiments; however, similarities were noted for rates of catch within the same experiment. For all experiments and observation hours, blend 95%E had the highest mean rate of catch.
