Efficiency and Longevity of Two Commercial Sex Pheromone Lures for Indianmeal Moth and Almond Moth (Lepidoptera: Pyralidae)

Two commercially available sex pheromone lures, a rubber septum and a controlled release membrane, that were impregnated with (Z,E)-9-12-tetradecadien-1-yl-acetate, were tested for efficiency and longevity in capturing released Indianmeal moths, Plodia interpunctella (Hübner), and almond moths, Cadra cautella (Walker), in a large warehouse. When both species were released simultaneously, traps baited with both types of lures captured 19–20% of the Indiandmeal moths but captured less than 1% of the almond moths. The lures remained attractive for over 40 wks.
