A newly developed female attractant marketed as Moth Suppression® was developed at Oklahoma State University’s Stored Product Insect Research Laboratory as another tool for monitoring and suppressing stored product moths. The effectiveness of the female moth attractant was tested on four species of stored product moths: Indian meal moth (IMM), Plodia interpunctella (Hübner); almond moth (AM), Cadra cautella (Walker); Mediterranean flour moth (MFM), Ephestia kuehniella (Zeller) and the rice moth (RM), Corcyra cephalonica (Stainton). After preliminary studies demonstrated that this attractant was effective in catching female Indian meal moths, it was tested on three other stored product moths. Each species was tested in a separate controlled trapping experiment over a 7 day period using 20 traps: 10 were baited with Moth Suppression® and ten were blank controls. A mean of 14.2 (±4.9) IMMs were captured in baited traps compared to a mean of 0.6 (±0.3) moths in the control traps. In the almond moth test, 3.7 (±1.2) moths were caught in baited traps while only 0.3 (±0.2) moths were captured in blank trap. For the Mediterranean flour moth, a mean of 1.9 (±0.5) moths were captured compared to 0.3 (±0.2) moths in control traps. The rice moth showed no significant response to the attractant. The lower trap catches of AM and MFM compared to IMM were possibly due to fewer moths released during the test. This study showed that three of the four stored product moths tested responded significantly to the female attractant.
