Technical Abstract: In recent years there has been increased interest throughout most developed countries in replacing older conventional neurotoxic insecticides used in pest management programs, including those used for stored products. Registrations for older compounds are being either withdrawn completely or altered to be applied in reduced application rates in combination with other insecticides. During the last decade in the United States, there have been several new or revised registrations for insecticides used on raw grain and in food storage facilities. Examples of these insecticides include inert dusts, insect growth regulators, bacterial pathogens, and new insecticides that affect metabolic pathways and receptors specific to insects. Research today includes not only the identification of potential new insecticides that can be used in stored-products, but also a thorough examination of the factors that can affect efficacy of these new insecticides. Physical and environmental factors, differences among target insect species, insecticidal formulations and methods of application, and the economics involved in determining effective application rates are just a few examples of these factors. In addition, some of these new insecticides can be combined for increased effectiveness, and can be specifically targeted for a particular insect species. Data from personal research studies will be used to illustrate concepts and ideas relevant to the diverse stored-product environments, from raw grain to urban storages. Topics for discussion include physical and environmental factors that affect insecticidal efficacy, methods of targeted applications, research with new insecticides, and new directions for insect pest management programs.
