Jim Campbell is a Research Entomologist with the USDA ARS Grain Marketing and Production Research Center in Manhattan, KS. He received B.S. and M.S. degrees from Rutgers University and a Ph.D. in Entomology from the University of California-Davis. His research interests include the behavior of stored product insects and their natural enemies and how the use of behavioral information can improve the management of insect pests.

Tribolium castaneum behavior near pheromone traps

The use of spatial information from pheromone monitoring programs for making pest management decisions in food facilities is complicated by environmental influences on trap capture and need to be taken into account when implementing and interpreting pheromone monitoring programs.

An Agent-Based Model for Simulating Red Flour Beetle Movement and Population Dynamics

Red flour beetle (Tribolium castaneum) is a common insect pest infesting flour mills. Over the last 80 years, dozens of mathematical models have been developed to simulate its population dynamics. However, while these models predict general population trends, they are not able to simulate individual behavior and movement, and most don’t include a spatial dimension. We built an agent-based model to explicitly represent individual beetles, fragmented landscapes, and the interactions between beetles as well as the interactions between beetles and their environment. Our model can be easily adjusted to different flour landscapes and different scales. The population dynamics, age structure, spatial distribution and movement behaviors are investigated in this agent-based model.

Beetle Immigration into Foundation Seed Warehouses

Understanding and eliminating routes of insect immigration into grain storage and processing facilities will provide new opportunities for targeted pest management. Stored-product Coleoptera were captured on unbaited rodent glue boards positioned on the floor, along the sides, and above overhead doors in Foundation Seed Warehouses located in Kansas and Nebraska. Traps were examined and replaced weekly from May through October 2004. To examine the effects of exclusion in paired tests, exterior rubber door gaskets were installed on one side of a door in Kansas and both doors in Nebraska. Species captured included the lesser grain borer, foreign grain beetle, rusty grain beetle, hairy fungus beetle, rice weevil and red flour beetle. When rubber gaskets were installed at the Kansas location, insect captures were concentrated at or near ground level suggesting that pest management efforts, such as residual spray applications, should be focused in these areas.

Detection of Stored-Grain Insect Infestation in Wheat Transported in Railroad Hopper-Cars

The specific objectives of this study were to determine (1) if IDK counts are indicative of insect infestation levels; (2) the age structure of the insect population in the infested railcars; and (3) the spatial distribution of insects and IDK in the grain mass.

Efficacy of Aerosols for Managing the Red Flour Beetle

Pest management professionals commonly utilize aerosolized liquid applications, also known as fogging, for management of stored-product insects including the red flour beetle. These applications are part of a potential methyl bromide replacement technology because they may increase the time interval between structural fumigations or heat treatments. The objectives of this study were to examine influence of flour accumulation, exposure location , life stage, and insecticide on the efficacy of aerosol applications. Data show that aerosolized insecticide applications in dishes without food residues placed in the open produced the highest red flour beetle mortality. Conversely, mortality significantly decreased with food and exposure under pallets.

Flight Activity of the Lesser Grain Borer Near Certified Seed Facilities

Rhyzopertha dominica (F.), lesser grain borer (LGB), is a serious pest of stored grain and grain processing facilities throughout temperate regions of the US. Foundation-certified seed stock facilities currently rely on application of chlorpyrifos-methyl directly to seed, applications of contact insecticides around the warehouse perimeter, and annual warehouse fumigation to manage this pest. The most common formulation of chlorpyrifos-methyl labeled for use on stored grain will no longer be available starting in 2005. To develop an IPM program for these facilities, LGB flight activity in and around a Kansas warehouse and the primary routes of insect immigration were studied. Results are broadly applicable to any grain storage or processing facility.

Fumigation Impact on Stored Product Insects in a Grain Processing Facility

Stored product insect pests reduce the quality of stored grain and processed grain products around the world. Losses to processed grain products are difficult to quantify but are undoubtedly greater because these products are more valuable yet have a lower pest tolerance than raw commodities. Insect management is important not only to maintain consumer confidence, but also because federal laws regulate insect presence in processing facilities and insect fragments in processed goods. Fumigation is the primary tool used to manage these insect infestations.

Patch utilization by the red flour beetle ( Tribolium castaneum)

The red flour beetle, Tribolium castaneum, is a major pest of flour mills and other food processing and storage facilities. The landscape of food processing and storage structures is a patchwork of unfavorable habitats and favorable habitats of varying quality and persistence. Understanding patch use behavior will help improve the management of pest populations in food processing and storage facilities.

Spatial and Temporal Patterns of Stored-Product Insect Flight Activity in a Kansas Landscape

Immigration of stored-product insects into food processing and storage facilities can be an important source of infestation. Although large numbers of stored-product insects can be captured outside food facilities, the sources of these insects and seasonal patterns to their flight activity are not well understood. In this study, seasonal patterns of outside flight activity were evaluated in a variety of habitat types in Kansas using pheromone traps. Temporal and spatial patterns of trap capture were determined for different pest species and habitat types. This information can be used to develop hypotheses about important source populations and recommendations about periods of time when facilities are susceptible to pest immigration.

Stored product insects in a flour mill: population dynamics, spatial distribution, dispersal behavior and implications for pest management

Methyl bromide is still widely used in food processing and storage facilities for the suppression of stored-product insect pests, but its use is scheduled to be phased out as part of the Montreal Protocol. Development of alternative tactics has been hampered by limited information available about pest population dynamics and spatial distribution at food facilities, fumigation efficacy, mechanisms by which populations rebound, and even how best to monitor pest populations. It is likely that many stored-product insect populations are made up of sub-populations interconnected by dispersal, therefore an important factor in evaluating management programs is to determine over what spatial scale these sub-populations are interacting. Pheromone trapping holds a great deal of promise as a monitoring tool, but because it captures dispersing individuals the relationship between pheromone trap capture and source populations needs to be established.
