The longevities of five commercial lures and one experimental lure for apple maggot were determined in laboratory and field tests in Utah. The Pherocon AM panel exhibited a reduced fly capture efficiency when aged for 9 d before use, which correlated well with the 5-d longevity observed in laboratory tests. The apple volatile lures made by Consep Membranes and Great Lakes IPM lasted at least 40 d in laboratory and field tests. However, the Ladd Industries rubber septum was found to last only about 4 d in the same tests. The implications of lure longevity on the present confusion over trap choice for monitoring apple maggot are discussed.
