The distribution and dispersal distances of insects outside of food processing and storage facilities potentially have an important influence on the population dynamics and spatial distribution of insects inside facilities. In this study, Trogoderma variabile Ballion and Plodia interpunctella (Hübner) sex pheromone-baited trap captures outside and inside a food processing facility were measured, the relationship between trap captures outside and inside the facility was evaluated, and the dispersal ability of the males of these species was assessed using self-mark-recapture stations. T. variabile and P. interpunctella males were captured in high numbers outside the food facility. The two species differed in their spatial distribution around the facility, with T. variabile being more closely associated with the proximity of the building, but most likely originating from sources outside the building. For marked T. variabile, the average recapture distance was 75 m (range 21-508 m) and for marked P. interpunctella the average recapture distance was 135.6 m (range 21-276 m). In an immigration/emigration experiment, three T. variabile marked outside were recaptured inside, but no T. variabile marked inside were recaptured outside and no marked P. interpunctella were recaptured in either location. The potential for outside populations to influence inside populations has implications for the effectiveness of different management and monitoring tools.
