Abstract
Five commercial pheromone trap designs were tested simultaneously in a warehouse to determine the most effective design for capturing Plodia interpunctella (Hübner) (the Indian meal moth). About 72% of the males released were recaptured. The most effective trap was the wing trap (Pherocon 1c), which significantly exceeded the expected value. The remaining trap designs in order of effectiveness were the diamond trap (Pherocon II), Multipher, Delta and Unitrap. Of these four traps, only the diamond trap equalled or slightly surpassed the expected catch number. The location of the traps affected the catch, with traps located near the walls of the warehouse capturing the most insects. Unbaited traps caught few insects, and the necessity of using unbaited traps in tests is discussed.
