Male and female Indian meal moths, Plodia interpunctella (Hübner), were captured in a commercial flour mill located in central Kansas; a Kansas State University (KSU) pilot flour mill and feed mill in Manhattan, KS; and in two retail pet food stores. Males and females of P. interpunctella were trapped using Pherocon II (Trécé, Adair, OK) sticky traps baited with a sex pheromone for males, whereas females were trapped using a commercial food lure from Insects Limited Inc. (Indianapolis, IN). Male and female traps were paired (spaced 19 cm apart) and arranged in a linear transect with a single unbaited Pherocon II trap separating both trap types. Traps were arranged uniformly across facility floors and were evenly distributed outside the perimeter of each facility. Indian meal moth self-marking stations were only used for the commercial flour mill to study the movement of wild Indian meal moth populations inside and outside the milling facility. For the KSU pilot flour and feed mills, the movement of Indian meal moths inside the facilities was studied by releasing marked pupae outdoors. Trapping in the two retail pet food stores was conducted to provide further evidence of the effectiveness of the commercial female lure. Preliminary studies have indicated that few female moths are being captured in the female traps. This result may be attributed to the actual abundance of female moths in this area, reduced attractiveness due to air movements, or the close proximity to the male traps.
