Abstract: Excerpt from the report: The use of high-frequency radio waves for killing insects is not new, but information on their effects on stored-grain insects is meager. To explore the possibilities in this field, cooperative studies of the effects of high-frequency electric fields on stored-product insects were conducted by the Stored-Product Insects Branch, Manhattan, Kans., and the Farm Electrification Research Branch, Agricultural Engineering Research Division, Agricultural Research Service, Lincoln, Nebr., during the period from September 1956 to June 1957. In these investigations different species and stages of stored-grain insects were exposed in a medium of wheat or wheat shorts to high-frequency electrical treatments of different frequencies and field intensities. Studies of mortality, injury, and insect reproduction after treatment were conducted to establish relationships between treatment variables and effects on the insects. Experimental results have also been examined for revelation of fundamental ideas concerning effects of high-frequency fields on the insects.
