Progress 09/15/05 to 09/14/07
Outputs
OUTPUTS: Field trials of new grain protectants and empty bin treatments for stored wheat confirmed that prevention can be achieved with low-risk insecticides. Aeration of stored wheat using computer-controlled bin fans demonstrated that grain temperatures could be effectively lowered in summer months. Heat treatments of empty grain bins were effective at killing insects in most bioassays. Further studies for effective heat treatment of concrete silos are needed. Aerosol and contact formulations of the insect growth regulator methoprene, alone or combined with pyrethrin or pyrethroid insecticides, can limit growth and development of the Indianmeal moth and storage beetles. Monitoring studies documented extensive populations of stored-product insects in and around food plants and storage facilities. Population growth patterns of insects inside and outside food plants are correlated, and such information will enable accurate timing of controls. Pheromone-based mating disruption to
suppress stored product moths was validated in commercial scale field trials. EPA registration of storage moth mating disruption was achieved, and technology transfer is proceeding via production of appropriate extension and outreach materials. A national training conference on integrated pest management in stored products was conducted in a "train-the-trainer" format in April 2007 that extended many research products from this project.
PARTICIPANTS: No changes in participants were made.
TARGET AUDIENCES: There is no new audience information
PROJECT MODIFICATIONS: No major project modifications were made.
Impacts
Pest management practices and new pest management tools studied in this project will provide low-risk, effective alternatives to traditional insecticide-based based methods for managing stored product insets in both raw grain and in value-added processed foods.

Progress 09/15/05 to 09/15/06
Outputs
The principals of sound pest management in both raw grain and value-added food products include prevention, monitoring, and effective, targeted suppression. This project focuses on specific strategies of prevention and suppression that can be adopted now or are near term in application, non-chemical in some cases, and either registered or in the registration process for use in raw grain and food processing situations. This project evaluating organophosphate alternatives for protecting stored grain and grain-based commodities focuses on two major components: protecting stored whole grain and protecting processed commodities in food processing and warehouse facilities. These approaches address the need to deal with commodity protection from farm to table. In the first objective, non-chemical alternatives for protecting farm stored grain will be assessed. Experiments are being carried out on the use of heat to disinfest residual insect populations in empty grain bins and
compare and contrast different methods for summer aeration of farm-stored wheat. In the second objective, organophosphate alternatives will be evaluated for protecting value-added food products in processing and warehouse facilities. Experiments are being done to develop and evaluate strategies for reducing insect movement into commodities or food facilities. Specific studies are determining the impact of aerosol insect growth regulator treatments on pest populations within food storage facilities and will assess the feasibility of pheromone-based mating disruption in commercial facilities to control the Indianmeal moth.
Impacts
Methods and techniques developed in this project will be aviaalbe for direct adoption by the pest management and food storage industries for effectgive pest control with limited insecticide inputs.
