“…While T. castaneum adults are long lived (up to 3 years), L. serricorne adults are very short lived [27] and a lack of reproduction combined with short lived adults likely explains capture differences between these two species in winter. Temperature was a very strong covariate of trap captures, which is consistent with other findings, as insect activity is decreased in cold climates [16,28,29]. Neither T. stercorea nor Carpophilus spp.…”

Insect populations were studied within two commercial peanut shelling facilities located in the southeastern United States. Commercially available pheromone/kairomone-baited dome traps and pheromone-baited flight traps were deployed throughout processing and shipping portions of the shelling plants and serviced weekly over one year. Lasioderma serricorne, Tribolium castaneum, Typhaea stercorea, Carpophilus spp., Plodia interpunctella and Cadra cautella were the most common captures across locations. Lasioderma serricorne made up 87% and 88% of all captures in dome traps in plants one and two, respectively. While L. serricorne was not captured during the winter months in flight traps, it was captured with near 100% frequency in dome traps, suggesting that populations persisted throughout the year inside the facilities. Tribolium castaneum populations were active year round. Across insect species and trap type, temperature was a significant covariate for explaining variation in insect counts. After accounting for the effect of temperature, there were always more insects captured in the processing portions of the facilities compared to the shipping areas. A negative linear relationship was observed between captures of L. serricorne and T. castaneum and trap distance from in-shell peanuts entering the shelling facilities. Conversely, fungivores were more evenly distributed throughout all parts of the shelling plants. These data suggest that management efforts should be focused where in-shell peanuts enter to reduce breeding and harborage sites for grain feeding insects.

Stored-product entomologists have a variety of new monitoring, decision-making, biological, chemical, and physical pest management tools available to them. Two types of stored-product insect populations are of interest: insects of immediate economic importance infesting commodities, and insects that live in food residues in equipment and facilities. The sampling and control methods change as grain and grain products move from field to consumer. There are also some changes in the major insect pest species to take into consideration. In this review, we list the primary insect pests at each point of the marketing system, and indicate which sampling methods and control strategies are most appropriate. Economic thresholds for insect infestation levels developed for raw commodity storage, processing plants, and retail business allow sampling-based pest management to be done before insect infestations cause economic injury. Taking enough samples to have a representative sample (20-30 samples) will generally provide enough information to classify a population as above or below an economic threshold.

“…One such approach is that at all facilities it is helpful to assess insect activity both indoors and outdoors, since patterns in insect captures helps us understand where there are significant insect reservoirs and potential for migrant insects to recolonize indoor areas following treatment. For example, at one food facility insect captures inside and outside of the building were correlated for Trogoderma variabile Ballion, but not for Plodia interpunctella (Hübner), and more T. variabile were captured overall than P. interpunctella [9], but at another location, indoor and outdoor captures of P. interpunctella were correlated [11,12]. Some patterns that have been found to be consistent at several different facilities include less insects outside of food patches, greater numbers on the outside or edges of food bulk, and higher captures near doors, windows and loading docks when outside activity is high [8,13,14].…”

“…There have been many monitoring studies in food facilities and several have investigated factors such as the number of traps needed for monitoring insect pests as well as the economic cost to employing these traps, but they have tended to focus on only a few years of data or monitoring only part of a facility [9,11,15,16]. Together, these studies suggest a large amount of variation in insect capture among different species [14] and locations [8,15,17], highlighting the importance of targeted integrated pest management (IPM) plans based on specific conditions at a facility [9,10,18,19].…”

“…Common features in a food facility such as doors, loading docks, and windows, can be used to connect interior and exterior sub-populations [8,10,14,25,26]. Spatial analysis and contour mapping based on insect captures and then superimposed onto floorplans allows researchers to identify patterns in distribution and correlate features of the facility with locations of high numbers of insects [10,11,20,22,27]. However, relationships between correlated environmental or landscape features at a trap location with consistently high or low insect captures are generally weak, which calls into question if these patterns can be meaningfully applied across facilities.…”

Using Long-term Capture Data to Predict Trogoderma variabile Ballion and Plodia interpunctella (Hübner) Population Patterns

Insects can infest facilities that house and process post-harvest grains and grain-based products. Integrated pest management tactics rely on tracking insect populations and using this information to select and target management tactics. Our ability to predict when and where to best focus treatment relies on an understanding of long-term trends, but often any available monitoring data are limited in its duration. Here we present data collected over a 10-year period at a flour mill in the central part of the United States. Using traps placed both inside and outside a flour mill and baited with pheromone-lures for Plodia interpunctella (Hübner), Indianmeal moth, and Trogoderma variabile Ballion, warehouse beetle, we examine environmental and spatial variability in insect captures. We find that both species, inside and outside the mill, are highly influenced by seasonal patterns, with peaks of insect captures during the warm season (April through September). There is also consistency across time and space in trap capture for P. interpunctella with traps in an open location consistently capturing high numbers of insects. In contrast, T. variabile lacked consistency in trap capture but were most often not found in the same trap locations as P. interpunctella. Fumigations conducted within the facility appeared to have little impact on insect captures inside, with dynamics appearing to be driven more by broader seasonal patterns in activity. These data and analyses suggest that there is a larger population of these insects that are readily moving in and out of the structures, while fumigation treatments are only impacting a small portion of the overall population and tactics targeting immigration may be an important addition to the pest management program.
