The pheromone system of the eastern tent caterpillar, M. americanum, has been identified as a mixture of (E,Z)-5,7-dodecadienal and the corresponding alcohol. Field data on the attractiveness of the aldehyde alone were not consistent, but mixtures of aldehyde and alcohol in varying proportions were attractive to males. Addition of small amounts of E,Z acetate to E,Z aldehyde had no effect on male response, but larger amounts reduced trap catch. Traps baited with Z,E,E,E, or Z,Z aldehydes were not more attractive than blank traps. Pherocon 1C traps fortified with extra adhesive and baited with lures consisting of 500 micrograms (E,Z)-5,7-dodecadienal with either 250 or 100 micrograms of the corresponding alcohol trapped as many as 100 males/trap/night with means of 15-20. Lures prepared from purified (94% E,Z) aldehyde and alcohol were more attractive than those prepared from unpurified (58% E,Z) materials.
