Previous studies demonstrated the ability of female Indianmeal moths, Plodia interpunctella(Hübner) (IMM), to locate oviposition sights by following airborne volatiles. An attractant was isolated and is a mixture of naturally occurring food volatiles for which a patent application has been filed and a commercial product is being sold under the name Moth Suppression®. The effectiveness of the female attractant at luring female IMMs to sticky traps was tested in a controlled laboratory study over a 7-day period in a large room in which approximately 600 adults were released. There were 10 diamond sticky traps baited with the female attractant and ten were blank controls. There were 14 ± 5 (mean ± SEM) female IMMs captured in baited traps compared to 0.6 ± 0.3 moths in the control traps. A separate field experiment was conducted in a warehouse in Winnipeg, Canada. Ten Moth Suppression® traps were baited with male and female IMM lures and placed in a small area of the warehouse that contained packaged pet treats. Monitoring of IMM with 10 Discrete® traps baited with just male IMM lures continued during the trapping with Moth Suppression® traps, as well as several months before and after the test. During the 17-week study a total of 67 females and 175 males were caught in the Moth Suppression® traps. Both studies demonstrated that the female attractant can be an effective new tool for monitoring female IMM.
